You may try using that with a suitable cable before buying any standalone power source for your board. Please ensure the expected output voltage
and current capabilities are listed on your power supply before attempting to power your board.
If you plan to use capes or add your own circuitry, higher amperage may be required.
Make sure that you have a grounded connection. This can be the USB cable or the HDMI cable.
If you plan to use capes or add your own circuitry, a power supply capable of higher current may be required.
.. note::
USB-C supplies will auto-negotiate the highest power mode that both power supply and BeagleBoard support. In most cases, this will be
5V @ 3A. It is OK to use a higher Wattage USB-C PD supply with a board, but it is recommended to use supplies from well-known manufacturers to
avoid supplies that may break the USB-C PD specification.

Introduction
###############
BeagleBone AI-64 like its predecessor :ref:`bbai-home`, is designed to address the
open-source community, early adopters, and anyone interested in a low cost 64-bit
Dual Arm® Cortex®-A72 processor based Single Board Computer (SBC). It also offers
access to many of the interfaces and allows for the use of add-on boards called
capes, to add many different combinations of features. A user may also develop
their own board or add their own circuitry.
.. note::
AI-64 has been equipped with a minimum set of features to allow the user to experience the power
of the processor and is not intended as a full development platform as many of the features and
interfaces supplied by the processor are not accessible from BeagleBone AI-64 via onboard support
of some interfaces. It is not a complete product designed to do any particular function. It is a
foundation for experimentation and learning how to program the processor and to access the
peripherals by the creation of your own software and hardware.

Methods of operation
*********************
1. Tethered to a PC
2. Standalone development platform in a PC configuration using external peripherals
.. _main-connection-scenarios:
Main Connection Scenarios
============================
This section describes how to connect and power the board and serves as a slightly more detailed
description of the Quick Start Guide included in the box. The board can be configured in several
different ways, but we will discuss the two most common scenarios.
* Tethered to a PC via the USB cable
* ``Board is accessed as a storage drive and virtual Ethernet connection.``
* Standalone Desktop
* ``Display``
* ``Keyboard and Mouse``
* ``External 5V > 3A power supply``
Each of these configurations is discussed in general terms in the following sections.
.. tab-set::
.. tab-item:: Tethered To A PC
In this configuration, the board is powered by the PC via a single USB cable. The board is accessed either as a USB storage drive or via the browser on the connected PC. You need to use either Firefox or Chrome on the PC, Internet Explorer will not work properly.
.. figure:: images/ch03/usb-tethering.*
:width: 740px
:align: center
Tethered Configuration
At least 5V @ 3A is required to power the board, In most cases the PC may not be able to supply
sufficient power for the board unless the connection is made over a Type-C to Type-C cable. You
should always use an external 5V > 3A DC power supply connected to the barrel jack if you are
unsure that the system can provide the required power or are otherwise using a USB-A to Type-C
cable which will always require power from the DC barrel jack.
**Connect the Cable to the Board**
1. Connect the type C USB cable to the board as shown in the figure below. The connector is on the top side of the board near barrel jack.
.. figure:: images/ch03/usb-c-connection.*
:width: 740px
:align: center
USB Connection to the Board
2. Connect the USB-A end of the cable to your PC or laptop USB port as shown in the figure below.
.. figure:: images/ch03/usb-a-connection.*
:width: 740px

USB Connection to the PC/Laptop
3. The board will power on and the power LED will be on as shown in the figure below.
.. figure:: images/ch03/power-led.*
:width: 740px
:align: center
Board Power LED
4. When the board starts to the booting process started by the process of applying power, the LEDs will come on in sequence as shown in the figure below. It will take a few seconds for the status LEDs to come on, so be patient. The LEDs will be flashing in an erratic manner as it begins to boot the Linux kernel.
.. figure:: images/ch03/led-pattern.*
:width: 740px
:align: center
Board Boot Status
**Accessing the Board as a Storage Drive**
The board will appear around a USB Storage drive on your PC after thekernel has booted, which will take a round 10 seconds. The kernel on the board needs to boot before the port gets enumerated. Once the board appears as a storage drive, do the following:
1. Open the USB Drive folder.
2. Click on the file named **start.htm**
3. The file will be opened by your browser on the PC and you should get a display showing the Quick Start Guide.
4. Your board is now operational! Follow the instructions on your PC screen.
.. tab-item:: Standalone w/Display and Keyboard/Mouse
In this configuration, the board works more like a PC, totally free from any connection to a PC as shown in the figure below. It allows you to create your code to make the board do whatever you need it to do. It will however require certain common PC accessories. These accessories and instructions are described in the following section.
.. figure:: images/ch03/desktop-configuration.*
:width: 740px
:align: center
Desktop Configuration
Ethernet cable and M.2 WiFi + Bluetooth card are optional. They can be used if network access required.
**Required Accessories**
In order to use the board in this configuration, you will need the following accessories:
* :ref:`5V > 3A power supply <accessories-power-supplies>`.
* :ref:`Display Port or HDMI monitor <accessories-displays>`.
* :ref:`miniDP-DP or active miniDP-HDMI cable <accessories-cables_minidp_hdmi>`.
* :ref:`USB wired/wireless keyboard and mouse <accessories-peripherals>`.
**Optional Accessories**
* Powered USB hub, The board has only two USB Type-A host ports, so you may need to use a powered USB Hub if you wish to add additional USB devices, such as a USB WiFi adapter.
* M.2 Bluetooth & WiFi module, For wireless connections, a USB WiFi adapter or a recommended M.2 WiFi module can provide wireless networking.
**Connecting Up the Board**
1. Connect the miniDP to DP or active miniDP to HDMI cable from your BeagleBone AI-64 to your monitor.
.. figure:: images/ch03/monitor-cable.*

1. The final step is to plug in the DC power supply to the DC power jack as shown in the figure below.
.. figure:: images/ch03/barrel-jack.*
:width: 740px
:align: center
External DC Power
1. The cable needed to connect to your display is a miniDP-DP or active miniDP-HDMI. Connect the miniDP connector end to the board at this time. The connector is on the top side of the board as shown in the figure below.
.. figure:: images/ch03/miniDP-connector.*
:width: 740px
:align: center
Connect miniDP to DP or active miniDP to HDMI Cable to the Board
The connector is fairly robust, but we suggest that you not use the cable as a leash for your Beagle. Take proper care not to put too much stress on the connector or cable.
1. Booting the Board
As soon as the power is applied to the board, it will start the booting up process. When the board starts to boot the LEDs will come on. It will take a few seconds for the status LEDs to come on, so be patient. The LEDs will be flashing in an erratic manner as it boots the Linux kernel.
.. figure:: images/ch03/leds.*

BeagleBone AI-64 LEDs
While the four user LEDS can be over written and used as desired, they do have specific
meanings in the image that is shipped with the board once the Linux kernel has booted.
* **USR0** is the heartbeat indicator from the Linux kernel.
* **USR1** turns on when the microSD card is being accessed
* **USR2** is an activity indicator. It turns on when the kernel is not in the idle loop.
* **USR3** turns on when the onboard eMMC is being accessed.
* **USR4** is an activity indicator for WiFi.
1. A Booted System
a. The board will have a mouse pointer appear on the screen as it enters the Linux boot step. You may have to move the physical mouse to get the mouse pointer to appear. The system can come up in the suspend mode with the monitor in a sleep mode.
b. After a minute or two a login screen will appear. You do not have to do anything at this point.
c. After a minute or two the desktop will appear. It should be similar to the one shown in the figure below. HOWEVER, it will change from one release to the next, so do not expect your system to look exactly like the one in the figure, but it will be very similar.
d. And at this point you are ready to go! The figure below shows the desktop after booting.

There are two boot modes:
.. _memory:
* **eMMC Boot:** This is the default boot mode and will allow for the fastest boot time and will enable the board to boot out of the box using the pre-flashed OS image without having to purchase an microSD card or an microSD card writer.
* **SD Boot:** This mode will boot from the microSD slot. This mode can be used to override what is on the eMMC device and can be used to program the eMMC when used in the manufacturing process or for field updates.
Memory
------------
.. important::
This section needs more work and references to greater detail. Other boot modes are possible.
Software to support USB and serial boot modes is not provided by beagleboard.org. Please contact TI for support of this feature.
Described in the following sections are the three memory devices found on the board.
.. _mb-ddr4l:
A switch is provided to allow switching between the modes.
4GB LPDDR4
************
* Holding the boot switch down during a removal and reapplication of power without a microSD card inserted will force the boot source to be the USB port and if nothing is detected on the USB client port, it will go to the serial port for download.
* Without holding the switch, the board will boot try to boot from the eMMC. If it is empty, then it will try booting from the microSD slot, followed by the serial port, and then the USB port.
* If you hold the boot switch down during the removal and reapplication of power to the board, and you have a microSD card inserted with a bootable image, the board will boot from the microSD card.
A single (1024M x 16bits x 2channels) LPDDR4 4Gb memory device is used. The memory used is:
.. note::
Pressing the RESET button on the board will NOT result in a change of the boot mode. You MUST remove power and reapply power to change the boot mode. The boot pins are sampled during power on reset from the PMIC to the processor.The reset button on the board is a warm reset only and will not force a boot mode change.

*********************************
Power Sources
==============
A single 16GB embedded MMC (eMMC) device is on the board. The device
connects to the MMC1 port of the processor, allowing for 8bit wide
access. Default boot mode for the board will be MMC1 with an option to
change it to MMC0, the SD card slot, for booting from the SD card as a
result of removing and reapplying the power to the board. Simply
pressing the reset button will not change the boot mode. MMC0 cannot be
used in 8Bit mode because the lower data pins are located on the pins
used by the Ethernet port. This does not interfere with SD card
operation but it does make it unsuitable for use as an eMMC port if the
8 bit feature is needed.
The board can be powered from three different sources:
* 5V > 3A power supply plugged into the barrel jack
* 5V > 3A capable device plugged into the USB Type-C connector
* The cape header pins
The power supply is not provided with the board but can be easily
obtained from numerous sources. A 5V > 3A supply is mandatory to have with
the board, but if there is a cape plugged into the board or you have a power
hungry device or hub plugged into the host port, then more current may
needed from the DC supply.

Power Management
*****************
BeagleBone AI-64 power management invludes a lot of ICs from Texas Instruments,
1. **DC/DC converter:** TPS62813 and LM5141
2. **LDO:** TPS74801
3. **PMICs:** TPS65941213 and TPS65941111
4. **Power Mux:** TPS2121
5. **Power Switch:** TPS22965
1V1 DC/DC
==========
TPS62813 is a 3-A synchronous step-down DC/DC converter with high efficiency and ease of use.
The TPS62813 family is based on a peak current mode control topology. The TPS62813
is designed for automotive applications such as infotainment and advanced driver assistance systems.
Low resistive switches allow up to 4-A continuous output current at high ambient temperature. The
switching frequency is externally adjustable from 1.8 MHz to 4 MHz and can also be synchronized to
an external clock in the same frequency range. In PWM/PFM mode, the TPS62813 automatically
enter power save mode at light loads to maintain high efficiency across the whole load range. The
TPS62813 provide 1% output voltage accuracy in PWM mode which helps design a power supply with
high output voltage accuracy. The SS/TR pin allows setting the start-up time or forming tracking of the
output voltage to an external source. This feature allows external sequencing of different supply rails
and limiting the inrush current during start-up.

1V1 & 2V5 LDO
==============
TPS74801 is a 1.5-A low-VIN (0.8 V) adjustable low-dropout (LDO) voltage regulator with power good and enable.
The TPS748 low-dropout (LDO) linear regulator provides an easy-to-use robust power management
solution for a wide variety of applications. User- programmable soft-start minimizes stress on the input
power source by reducing capacitive inrush current on start-up. The soft-start is monotonic and designed
for powering many different types of processors and ASICs. The enable input and power-good output
allow easy sequencing with external regulators. This complete flexibility allows a solution to be configured
that meets the sequencing requirements of FPGAs, DSPs, and other applications with special start-up requirements.

The LM5141 is a synchronous buck controller, intended for high voltage wide VIN step-down
converter applications. The control method is peak current mode control. Current mode control provides
inherent line feed-forward, cycle-by-cycle current limiting, and ease of loop compensation. The LM5141
features slew rate control to simplify the compliance with EMI requirements. The LM5141 has two selectable switching
frequencies: 2.2 MHz and 440 kHz. Gate Drivers with Slew Rate Control that can be adjusted to reduce EMI.
In light or no-load conditions, the LM5141 operates in skip cycle mode for improved low power efficiency.
The LM5141 has a high voltage bias regulator with automatic switch-over to an external bias to reduce
the IQ current from VIN. Additional features include frequency synchronization, cycle-by-cycle current
limit, hiccup mode fault protection for sustained overload, and power good output.

Power mux
==========
TPS2121 is a 2.7-V to 22-V, 56-mΩ, 4.5-A, power mux with seamless switchover. The TPS212x devices are Dual-Input, Single-Output
(DISO) Power Multiplexer (MUX) that are well suited for a variety of systems having multiple power
sources. The devices will Automatically Detect, Select, and Seamlessly Transition between available inputs.
Priority can be automatically given to the highest input voltage or manually assigned to a lower voltage
input to support both ORing and Source Selection operations. A priority voltage supervisor is used to
select an input source. An Ideal Diode operation is used to seamlessly transition between input sources. During switchover,
the voltage drop is controlled to block reverse current before it happens and provide uninterrupted power to
the load with minimal hold-up capacitance. Current limiting is used during startup and switchover
to protect against overcurrent events, and also protects the device during normal operation. The
output current limit can be adjusted with a single external resistor.

Load switch
============
TPS22965 is a 5.7-V, 6-A, 16-mΩ load switch with adj. rise time and optional output discharge.
The TPS22965 is a single channel load switch that provides configurable rise time to minimize inrush
current. The device contains an N-channel MOSFET that can operate over an input voltage range of 0.8 V
to 5.7 V and can support a maximum continuous current of 6 A. The switch is controlled by an on and
off input (ON), which is capable of interfacing directly with low-voltage control signals. In the TPS22965, a
225-Ω on-chip load resistor is added for quick output discharge when switch is turned off

As mentioned earlier, there are two boot modes:
MikroBus port
==============
* **eMMC Boot:** This is the default boot mode and will allow for the fastest boot time and will enable the board to boot out of the box using the pre-flashed OS image without having to purchase an microSD card or an microSD card writer.
* **SD Boot:** This mode will boot from the microSD slot. This mode can be used to override what is on the eMMC device and can be used to program the eMMC when used in the manufacturing process or for field updates.

* Without holding the switch, the board will boot try to boot from the eMMC. If it is empty, then it will try booting from the microSD slot, followed by the serial port, and then the USB port.
* If you hold the boot switch down during the removal and reapplication of power to the board, and you have a microSD card inserted with a bootable image, the board will boot from the microSD card.

provide power on/off control and up to 1.5A of current at 5V. Under USB
power, the board will not be able to supply the full 1.5A, but should
be sufficient to supply enough current for a lower power USB device
supplying power between 50 to 100mA.

The power supply is not provided with the board but can be easily
obtained from numerous sources. A 5V > 3A supply is mandatory to have with
the board, but if there is a cape plugged into the board or you have a power
hungry device or hub plugged into the host port, then more current may

A single 16GB embedded MMC (eMMC) device is on the board. The device
connects to the MMC1 port of the processor, allowing for 8bit wide
access. Default boot mode for the board will be MMC1 with an option to
change it to MMC0, the SD card slot, for booting from the SD card as a
result of removing and reapplying the power to the board. Simply
pressing the reset button will not change the boot mode. MMC0 cannot be
used in 8Bit mode because the lower data pins are located on the pins
used by the Ethernet port. This does not interfere with SD card
operation but it does make it unsuitable for use as an eMMC port if the
8 bit feature is needed.

Cape Board Support
===================
*BeagleBone AI-64* has the ability to accept up to
four EEPROM addressable expansion boards or capes stacked onto
the expansion headers. The word cape comes from the shape of the
expansion board for BeagleBone boards as it is fitted around the
Ethernet connector on the main board. For BeagleBone this notch acts as a
key to ensure proper orientation of the cape. On AI-64 you can see a clear
silkscreen marking for the cape orientation. Most of BeagleBone capes
can be used with your BeagleBone AI-64 also like shown in :ref:`bbai64-cape-placement-figure` below.

other capes that are intended to coexist with each other. Co-existence
is not a requirement and is in itself, something that is impossible to
control or administer. But, people will be able to create capes that
operate with other capes that are already available based on public
information as it pertains to what pins and features each cape uses.
This information will be able to be read from the EEPROM on each cape.
For those wanting to create their own capes this should not put limits on the creation of
capes and what they can do, but may set a few basic rules that will allow
the software to administer their operation with BeagleBone AI-64. For this
reason there is a lot of flexibility in the specification that we hope
most people will find it liberating in the spirit of Open Source
Hardware. On the other hand we are sure that there are others who would like to see tighter
control, more details, more rules and much more order to the way capes
are handled.
Over time, this specification will change and be updated, so please
refer to the `latest version of this manual <https://git.beagleboard.org/beagleboard/beaglebone-ai-64/>`_
prior to designing your own capes to get the latest information.
.. warning::
Do not apply voltage to any I/O pin when power is not supplied to the board.
It will damage the processor and void the warranty.
.. _beaglebone-ai-64-cape-compatibility:
BeagleBone AI-64 Cape Compatibility
------------------------------------
The expansion headers on BeagleBone Black and BeagleBone AI-64 provides
similar pin configuration options on P8 and P9 expansion header pins thus provide
cape compatibility to a certain extent. Which means most BeagleBone Black capes
will also be compatible with BeeagleBone AI-64.
See :ref:`beaglebone-cape-interface-spec` for compatibility information.
.. todo

.. _bbai64-eeprom:
EEPROM
--------
Each cape must have its own EEPROM containing information that will
allow the software to identify the board and to configure the expansion
headers pins during boot as needed. The one exception is proto boards intended for
prototyping. They may or may not have an EEPROM on them. An EEPROM is
required for all capes sold in order for them operate correctly when
plugged into BeagleBone AI-64.
The address of the EEPROM will be set via either jumpers or a dipswitch
on each expansion board. :ref:`expansion-board-eeprom-without-write-protect-figure`
below is the design of the EEPROM circuit.
.. _expansion-board-eeprom-without-write-protect-figure:
.. figure:: images/ch08/eeprom.*
:width: 740
:align: center
Expansion board EEPROM without write protect
The addressing of this device requires two bytes for the address which
is not used on smaller size EEPROMs, which only require only one byte.
Other compatible devices may be used as well. Make sure the device you
select supports 16 bit addressing. The part package used is at the
discretion of the cape designer.
.. _eeprom-address:
EEPROM Address
~~~~~~~~~~~~~~
In order for each cape to have a unique address, a board ID scheme is
used that sets the address to be different depending on the setting of
the dipswitch or jumpers on the capes. A two position dipswitch or
jumpers is used to set the address pins of the EEPROM.
It is the responsibility of the user to set the proper address for each
board and the position in the stack that the board occupies has nothing
to do with which board gets first choice on the usage of the expansion
bus signals. The process for making that determination and resolving
conflicts is left up to the SW and, as of this moment in time, this
method is a something of a mystery due to the new Device Tree
methodology introduced in the 3.8 kernel.
Address line A2 is always tied high. This sets the allowable address
range for the expansion cards to *0x54* to**0x57**. All other I2C
addresses can be used by the user in the design of their capes. But,
these addresses must not be used other than for the board EEPROM
information. This also allows for the inclusion of EEPROM devices on the
cape if needed without interfering with this EEPROM. It requires that A2
be grounded on the EEPROM not used for cape identification.
.. _i2c-bus:
I2C Bus
~~~~~~~~~
The EEPROMs on each expansion board are connected to I2C2 on connector
P9 pins 19 and 20. For this reason I2C2 must always be left connected
and should not be changed by SW to remove it from the expansion header
pin mux settings. If this is done, the system will be unable to detect
the capes.
The I2C signals require pullup resistors. Each board must have a 5.6K
resistor on these signals. With four capes installed this will result in
an effective resistance of 1.4K if all capes were installed and all the
resistors used were exactly 5.6K. As more capes are added the resistance
is reduced to overcome capacitance added to the signals. When no capes
are installed the internal pullup resistors must be activated inside the
processor to prevent I2C timeouts on the I2C bus.
The I2C2 bus may also be used by capes for other functions such as I/O
expansion or other I2C compatible devices that do not share the same
address as the cape EEPROM.
.. _eeprom-write-protect:
EEPROM Write Protect
~~~~~~~~~~~~~~~~~~~~~
The design in :ref:`expansion-board-eeprom-with-write-protect-figure`
has the write protect disabled. If the write
protect is not enabled, this does expose the EEPROM to being corrupted
if the I2C2 bus is used on the cape and the wrong address written to. It
is recommended that a write protection function be implemented and a
Test Point be added that when grounded, will allow the EEPROM to be
written to. To enable write operation, Pin 7 of the EEPROM must be tied
to ground.
When not grounded, the pin is HI via pullup resistor R210 and therefore
write protected. Whether or not Write Protect is provided is at the
discretion of the cape designer.

Pin Usage Consideration
------------------------
This section covers things to watch for when hooking up to certain pins
on the expansion headers.
.. _expansion-connectors-1:
Expansion Connectors
--------------------
A combination of male and female headers is used for access to the
expansion headers on the main board. There are three possible mounting
configurations for the expansion headers:
* **Single** -no board stacking but can be used on the top of the stack.
* **Stacking-up** to four boards can be stacked on top of each other.
* **Stacking with signal stealing-up** to three boards can be stacked on top of each other, but certain boards will not pass on the signals they are using to prevent signal loading or use by other cards in the stack.
The following sections describe how the connectors are to be implemented
and used for each of the different configurations.
.. _non-stacking-headers-single-cape:
Non-Stacking Headers-Single Cape
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For non-stacking capes single configurations or where the cape can be
the last board on the stack, the two 46 pin expansion headers use the
same connectors. :ref:`single-expansion-connector-figure` is a picture of
the connector. These are dual row 23 position 2.54mm x 2.54mm connectors.
.. _single-expansion-connector-figure:
.. figure:: images/ch08/single-expansion-connector.*
:width: 740
:align: center
Single expansion connector
The connector is typically mounted on the bottom side of the board as
shown in :ref:`single-cape-expansion-connector-figure` . These are very
common connectors and should be easily located. You can also use two
single row 23 pin headers for each of the dual row headers.

It is allowed to only populate the pins you need. As this is a
non-stacking configuration, there is no need for all headers to be
populated. This can also reduce the overall cost of the cape. This
decision is up to the cape designer.
For convenience listed in :ref:`single-cape-connectors-figure` are some possible
choices for part numbers on this connector. They have varying pin lengths and
some may be more suitable than others for your use. It should be noted, that the
longer the pin and the further it is inserted into BeagleBone AI-64
connector, the harder it will be to remove due to the tension on 92
pins. This can be minimized by using shorter pins or removing those pins
that are not used by your particular design. The first item in**Table
18** is on the edge and may not be the best solution. Overhang is the
amount of the pin that goes past the contact point of the connector on
BeagleBone AI-64

The G in the part number is a plating option. Other options may be used
as well as long as the contact area is gold. Other possible sources are

There are also different plating options on each of the connectors
above. Gold plating on the contacts is the minimum requirement. If you
choose to use a different part number for plating or availability
purposes, make sure you do not select the “LT” option.
Other possible sources are Sullins and Samtec but make sure you select
one that has the correct mating depth.
.. _stacked-capes-wsignal-stealing:
Stacked Capes w/Signal Stealing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
:ref:`stacked-with-signal-stealing-expansion-connector-figure` is the connector configuration for stackable capes that does
not provide all of the signals upwards for use by other boards. This is
useful if there is an expectation that other boards could interfere with
the operation of your board by exposing those signals for expansion.
This configuration consists of a combination of the stacking and
nonstacking style connectors.

.. _retention-force:
Retention Force
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The length of the pins on the expansion header has a direct relationship
to the amount of force that is used to remove a cape from BeagleBone
AI-64. The longer the pins extend into the connector the harder it is to
remove. There is no rule that says that if longer pins are used, that
the connector pins have to extend all the way into the mating connector
on BeagleBone AI-64, but this is controlled by the user and
therefore is hard to control. We have also found that if you use gold
pins, while more expensive, it makes for a smoother finish which reduces
the friction.
This section will attempt to describe the tradeoffs and things to
consider when selecting a connector and its pin length.
.. _beaglebone-ai-64-female-connectors:
BeagleBone AI-64 Female Connectors
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
:ref:`connector-pin-insertion-depth` shows the key measurements used in calculating how much the
pin extends past the contact point on the connector, what we call
overhang.
.. _connector-pin-insertion-depth:
.. figure:: images/ch08/berg-stip-insertion.*
:width: 400px
:align: center
:alt: Connector Pin Insertion Depth
Connector Pin Insertion Depth
To calculate the amount of the pin that extends past the Point of
Contact, use the following formula:
Overhang=Total Pin Length- PCB thickness (.062) - contact point (.079)
The longer the pin extends past the contact point, the more force it
will take to insert and remove the board. Removal is a greater issue
than the insertion.
.. _signal-usage:
Signal Usage
~~~~~~~~~~~~
Based on the pin muxing capabilities of the processor, each expansion
pin can be configured for different functions. When in the stacking
mode, it will be up to the user to ensure that any conflicts are
resolved between multiple stacked cards. When stacked, the first card
detected will be used to set the pin muxing of each pin. This will
prevent other modes from being supported on stacked cards and may result
in them being inoperative.
In :ref:`beaglebone-ai-64-connectors` section of this document, the
functions of the pins are defined as well as the pin muxing options.
Refer to this section for more information on what each pin is. To
simplify things, if you use the default name as the function for each
pin and use those functions, it will simplify board design
and reduce conflicts with other boards.
Interoperability is up to the board suppliers and the user. This
specification does not specify a fixed function on any pin and any pin
can be used to the full extent of the functionality of that pin as
enabled by the processor.
*DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE
BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.*

The :ref:`expansion-header-voltages-table` describes the voltages from the
main board that are available on the expansion connectors and their ratings.
All voltages are supplied by connector**P9**. The current ratings listed are per pin.

The *VSYS_IO_3V3* rail is supplied by the LDO on BeagleBone AI-64 and
is the primary power rail for expansion boards. If the power requirement
for the capes exceeds the current rating, then locally generated voltage
rail can be used. It is recommended that this rail be used to power any
buffers or level translators that may be used.
*DC_VDD_5V* is the main power supply from the DC input jack. This voltage
is not present when the board is powered via USB. The amount of current
supplied by this rail is dependent upon the amount of current available.
Based on the board design, this rail is limited to 1A per pin from the
main board.
The *VSYS_5V0* rail is the main rail for the regulators on the main board.
When powered from a DC supply or USB, this rail will be 5V. The
available current from this rail depends on the current available from
the USB and DC external supplies.
.. _expansion-board-external-power:
Expansion Board External Power
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A cape can have a jack or terminals to bring in whatever voltages may be
needed by that board. Care should be taken not to let this voltage be
fed back into any of the expansion header pins.
It is possible to provide 5V to the main board from an expansion board.
By supplying a 5V signal into the *DC_VDD_5V* rail, the main board can be
supplied. This voltage must not exceed 5V. You should not supply any
voltage into any other pin of the expansion connectors. Based on the
board design, this rail is limited to 1A per pin to BeagleBone
AI-64.
*There are several precautions that need to be taken when working with
the expansion headers to prevent damage to the board.*
1. *Do not apply any voltages to any I/O pins when the board is not powered on.*
2. *Do not drive any external signals into the I/O pins until after the VSYS_IO_3V3 rail is up.*
3. *Do not apply any voltages that are generated from external sources.*
4. *If voltages are generated from the DC_VDD_5V signal, those supplies must not become active until after the VSYS_IO_3V3 rail is up.*
5. *If you are applying signals from other boards into the expansion headers, make sure you power the board up after you power up the BeagleBone AI-64 or make the connections after power is applied on both boards.*
*Powering the processor via its I/O pins can cause damage to the processor.*

Introduction
###############
This document is the *System Reference Manual* for BeagleBone AI-64
and covers its use and design. The board will primarily be referred to
in the remainder of this document simply as the board, although it may
also be referred to as AI-64 or BeagleBone AI-64 as a reminder.
This design is subject to change without notice as we will work to keep
improving the design as the product matures based on feedback and
experience. Software updates will be frequent and will be independent of
the hardware revisions and as such not result in a change in the
revision number.
Make sure you frequently check the `BeagleBone AI-64 git repository <https://git.beagleboard.org/beagleboard/beaglebone-ai-64/>`_ for the most up to date support documents.

Methods of operation
----------------------
1. Tethered to a PC
2. Standalone development platform in a PC configuration using external peripherals
.. _whats-in-the-box:
What’s In the Box
---------------------------
In the box you will find three main items as shown in :ref:`bbai-64-pacakage`.
* BeagleBone AI-64.
* Instruction card.
A USB-C to USB-C cable is not included bot recommended for the tethered scenario and creates an out of box experience where the board can be used immediately with no other equipment needed.

.. _main-connection-scenarios:
Main Connection Scenarios
-------------------------------
This section describes how to connect and power the board and serves as a slightly more detailed description of the Quick Start Guide included in the box.
The board can be configured in several different ways, but we will discuss the two most common scenarios.
* Tethered to a PC via the USB cable
* ``Board is accessed as a storage drive and virtual Ethernet connection.``
* Standalone Desktop
* ``Display``
* ``Keyboard and Mouse``
* ``External 5V > 3A power supply``
Each of these configurations is discussed in general terms in the following sections.
.. _tethered-to-a-pc:
Tethered To A PC
-------------------------
In this configuration, the board is powered by the PC via a single USB cable. The board is accessed either as a USB storage drive or via the browser on the connected PC. You need to use either Firefox or Chrome on the PC, Internet Explorer will not work properly.
.. _tethered-figure:
.. figure:: images/ch03/usb-tethering.jpg
:width: 400px
:align: center
:alt: Tethered Configuration
Fig: Tethered Configuration
At least 5V @ 3A is required to power the board, In most cases the PC may not be able to supply sufficient power for the board unless the connection is made over a Type-C to Type-C cable. You should always use an external 5V > 3A DC power supply connected to the barrel jack if you are unsure that the system can provide the required power or are otherwise using a USB-A to Type-C cable which will always require power from the DC barrel jack.
.. _connect-the-cable-to-the-board:
Connect the Cable to the Board
*************************************
1. Connect the type C USB cable to the board as shown in :ref:`usb-c-connect-figure`. The connector is on the top side of the board near barrel jack.

.. _accessing-the-board-as-a-storage-drive:
Accessing the Board as a Storage Drive
***********************************************
The board will appear around a USB Storage drive on your PC after thekernel has booted, which will take a round 10 seconds. The kernel on the board needs to boot before the port gets enumerated. Once the board appears as a storage drive, do the following:
1. Open the USB Drive folder.
2. Click on the file named **start.htm**
3. The file will be opened by your browser on the PC and you should get a display showing the Quick Start Guide.
4. Your board is now operational! Follow the instructions on your PC screen.
.. _standalone-wdisplay-and-keyboardmouse:
Standalone w/Display and Keyboard/Mouse
-----------------------------------------------
In this configuration, the board works more like a PC, totally free from any connection to a PC as shown in :ref:`desktop-config-figure`. It allows you to create your code to make the board do whatever you need it to do. It will however require certain common PC accessories. These accessories and instructions are described in the following section.
.. _desktop-config-figure,Desktop Configuration figure:
.. figure:: images/ch03/desktop-configuration.jpg
:width: 400px
:align: center
:alt: Desktop Configuration
Fig: Desktop Configuration
Ethernet cable and M.2 WiFi + Bluetooth card are optional. They can be used if network access required.
.. _required-accessories:
Required Accessories
***************************
In order to use the board in this configuration, you will need the following accessories:
* 5V > 3A power supply.
* Display Port or HDMI monitor.
* miniDP-DP or active miniDP-HDMI cable (or a recommended **miniDP-DP or active miniDP-HDMI adapter** https://www.amazon.com/dp/B089GF8M87 has been tested and worked beautifully).
* USB wired/wireless keyboard and mouse.
* powered USB HUB (OPTIONAL). The board has only two USB Type-A host ports, so you may need to use a powered USB Hub if you wish to add additional USB devices, such as a USB WiFi adapter.
* M.2 Bluetooth & WiFi module (OPTIONAL). For wireless connections, a USB WiFi adapter or a recommended M.2 WiFi module can provide wireless networking.
.. _connecting-up-the-board:
Connecting Up the Board
******************************
1. Connect the miniDP to DP or active miniDP to HDMI cable from your BeagleBone AI-64 to your monitor.

:align: center
:alt: Keyboard and Mouse
FigKeyboard and Mouse
4. Connect the Ethernet Cable
If you decide you want to connect to your local area network, an Ethernet cable can be used. Connect the Ethernet Cable to the Ethernet port as shown in :ref:`ethernet-cable-figure`. Any standard 100M Ethernet cable should work.
.. _ethernet-cable-figure:
.. figure:: images/ch03/ethernet-cable.jpg
:width: 400px
:align: center
:alt: Ethernet Cable Connection
Fig: Ethernet Cable Connection
5. The final step is to plug in the DC power supply to the DC power jack as shown in :ref:`barrel-jack-figure` below.
.. _barrel-jack-figure,External DC Power figure:
.. figure:: images/ch03/barrel-jack.jpg
:width: 400px
:align: center
:alt: External DC Power
Fig: External DC Power
6. The cable needed to connect to your display is a miniDP-DP or active miniDP-HDMI. Connect the miniDP connector end to the board at this time. The connector is on the top side of the board as shown in :ref:`miniDP-figure` below.
.. _miniDP-figure,miniDP to DP or active miniDP to HDMI connection figure:
.. figure:: images/ch03/miniDP-connector.jpg
:width: 400px
:align: center
:alt: Connect miniDP to DP or active miniDP to HDMI Cable to the Board
Fig: Connect miniDP to DP or active miniDP to HDMI Cable to the Board
The connector is fairly robust, but we suggest that you not use the cable as a leash for your Beagle. Take proper care not to put too much stress on the connector or cable.
7. Booting the Board
As soon as the power is applied to the board, it will start the booting up process. When the board starts to boot the LEDs will come on. It will take a few seconds for the status LEDs to come on, so be patient. The LEDs will be flashing in an erratic manner as it boots the Linux kernel.
.. _LEDs-figure,BeagleBone AI-64 LEDs figure:
.. figure:: images/ch03/leds.jpg
:width: 400px
:align: center
:alt: BeagleBone AI-64 LEDs
Fig: BeagleBone AI-64 LEDs
While the four user LEDS can be over written and used as desired, they do have specific meanings in the image that is shipped with the board once the Linux kernel has booted.
* **USR0** is the heartbeat indicator from the Linux kernel.
* **USR1** turns on when the microSD card is being accessed
* **USR2** is an activity indicator. It turns on when the kernel is not in the idle loop.
* **USR3** turns on when the onboard eMMC is being accessed.
* **USR4** is an activity indicator for WiFi.
8. A Booted System
a. The board will have a mouse pointer appear on the screen as it enters the Linux boot step. You may have to move the physical mouse to get the mouse pointer to appear. The system can come up in the suspend mode with the monitor in a sleep mode.
b. After a minute or two a login screen will appear. You do not have to do anything at this point.
c. After a minute or two the desktop will appear. It should be similar to the one shown in :ref:`figure-16`. HOWEVER, it will change from one release to the next, so do not expect your system to look exactly like the one in the figure, but it will be very similar.
d. And at this point you are ready to go! :ref:`figure-16` shows the desktop after booting.

BeagleBone AI-64 Overview
###############################
BeagleBone AI-64 is the latest addition to BeagleBoard.org family and like its predecessors, is designed to address the open-source Community, early adopters, and anyone interested in a low cost 64-bit Dual Arm® Cortex®-A72 processor based Single Board Computer (SBC).
It has been equipped with a minimum set of features to allow the user to
experience the power of the processor and is not intended as a full
development platform as many of the features and interfaces supplied by
the processor are not accessible from BeagleBone AI-64 via onboard
support of some interfaces. It is not a complete product designed to do
any particular function. It is a foundation for experimentation and
learning how to program the processor and to access the peripherals by
the creation of your own software and hardware.
It also offers access to many of the interfaces and allows for the use
of add-on boards called capes, to add many different combinations of
features. A user may also develop their own board or add their own
circuitry.
BeagleBone AI-64 is manufactured and warranted by partners listed at https://beagleboard.org/logo for the benefit of the community and its supporters including the current BeagleBoard.org Foundation board members
* Jason Kridner, principal of JK Embedded Consulting an independent contractor and architect for new Beagle designs.
* Drew Fustini, independent Linux developer
* Robert Nelson, applications engineer at Digi-Key
* Mark Yoder, professor at Rose-Hulman Institute of Technology
* Kathy Giori, product engineer at ZEDEDA
See `bbb.io/about <https://beagleboard.org/about>`_
BeagleBone AI-64 has been designed by Seeed Studio (Seeed Development Limited) under guidance from BeagleBoard.org Foundation.

Cape Board Support
#######################
*BeagleBone AI-64* has the ability to accept up to
four EEPROM addressable expansion boards or capes stacked onto
the expansion headers. The word cape comes from the shape of the
expansion board for BeagleBone boards as it is fitted around the
Ethernet connector on the main board. For BeagleBone this notch acts as a
key to ensure proper orientation of the cape. On AI-64 you can see a clear
silkscreen marking for the cape orientation. Most of BeagleBone capes
can be used with your BeagleBone AI-64 also like shown in :ref:`bbai-cape-placement-figure` below.

This section describes the rules & guidelines for creating capes to ensure proper
operation with BeagleBone AI-64 and proper interoperability with
other capes that are intended to coexist with each other. Co-existence
is not a requirement and is in itself, something that is impossible to
control or administer. But, people will be able to create capes that
operate with other capes that are already available based on public
information as it pertains to what pins and features each cape uses.
This information will be able to be read from the EEPROM on each cape.
For those wanting to create their own capes this should not put limits on the creation of
capes and what they can do, but may set a few basic rules that will allow
the software to administer their operation with BeagleBone AI-64. For this
reason there is a lot of flexibility in the specification that we hope
most people will find it liberating in the spirit of Open Source
Hardware. On the other hand we are sure that there are others who would like to see tighter
control, more details, more rules and much more order to the way capes
are handled.
Over time, this specification will change and be updated, so please
refer to the `latest version of this manual <https://git.beagleboard.org/beagleboard/beaglebone-ai-64/>`_
prior to designing your own capes to get the latest information.
.. warning::
Do not apply voltage to any I/O pin when power is not supplied to the board.
It will damage the processor and void the warranty.
.. _beaglebone-ai-64-cape-compatibility:
BeagleBone AI-64 Cape Compatibility
-------------------------------------------
The expansion headers on BeagleBone Black and BeagleBone AI-64 provides
similar pin configuration options on P8 and P9 expansion header pins thus provide
cape compatibility to a certain extent. Which means most BeagleBone Black capes
will also be compatible with BeeagleBone AI-64.
.. important::
This section is still being worked on, please make sure you have the latest system reference manual (SRM).
.. todo
Add BeagleBone AI-64 LCD pins information.
Add BeagleBone AI-64 eMMC pins information.
.. _eeprom:
EEPROM
-------------------------------------------
Each cape must have its own EEPROM containing information that will
allow the software to identify the board and to configure the expansion
headers pins during boot as needed. The one exception is proto boards intended for
prototyping. They may or may not have an EEPROM on them. An EEPROM is
required for all capes sold in order for them operate correctly when
plugged into BeagleBone AI-64.
The address of the EEPROM will be set via either jumpers or a dipswitch
on each expansion board. :ref:`expansion-board-eeprom-without-write-protect-figure`
below is the design of the EEPROM circuit.
.. _expansion-board-eeprom-without-write-protect-figure:
.. figure:: images/ch08/eeprom.png
:width: 400px
:align: center
:alt: Fig-Expansion board EEPROM without write protect
Fig-Expansion board EEPROM without write protect
The addressing of this device requires two bytes for the address which
is not used on smaller size EEPROMs, which only require only one byte.
Other compatible devices may be used as well. Make sure the device you
select supports 16 bit addressing. The part package used is at the
discretion of the cape designer.
.. _eeprom-address:
EEPROM Address
***************************
In order for each cape to have a unique address, a board ID scheme is
used that sets the address to be different depending on the setting of
the dipswitch or jumpers on the capes. A two position dipswitch or
jumpers is used to set the address pins of the EEPROM.
It is the responsibility of the user to set the proper address for each
board and the position in the stack that the board occupies has nothing
to do with which board gets first choice on the usage of the expansion
bus signals. The process for making that determination and resolving
conflicts is left up to the SW and, as of this moment in time, this
method is a something of a mystery due to the new Device Tree
methodology introduced in the 3.8 kernel.
Address line A2 is always tied high. This sets the allowable address
range for the expansion cards to *0x54* to**0x57**. All other I2C
addresses can be used by the user in the design of their capes. But,
these addresses must not be used other than for the board EEPROM
information. This also allows for the inclusion of EEPROM devices on the
cape if needed without interfering with this EEPROM. It requires that A2
be grounded on the EEPROM not used for cape identification.
.. _i2c-bus:
I2C Bus
***************************
The EEPROMs on each expansion board are connected to I2C2 on connector
P9 pins 19 and 20. For this reason I2C2 must always be left connected
and should not be changed by SW to remove it from the expansion header
pin mux settings. If this is done, the system will be unable to detect
the capes.
The I2C signals require pullup resistors. Each board must have a 5.6K
resistor on these signals. With four capes installed this will result in
an effective resistance of 1.4K if all capes were installed and all the
resistors used were exactly 5.6K. As more capes are added the resistance
is reduced to overcome capacitance added to the signals. When no capes
are installed the internal pullup resistors must be activated inside the
processor to prevent I2C timeouts on the I2C bus.
The I2C2 bus may also be used by capes for other functions such as I/O
expansion or other I2C compatible devices that do not share the same
address as the cape EEPROM.
.. _eeprom-write-protect:
EEPROM Write Protect
***************************
The design in :ref:`expansion-board-eeprom-with-write-protect-figure`
has the write protect disabled. If the write
protect is not enabled, this does expose the EEPROM to being corrupted
if the I2C2 bus is used on the cape and the wrong address written to. It
is recommended that a write protection function be implemented and a
Test Point be added that when grounded, will allow the EEPROM to be
written to. To enable write operation, Pin 7 of the EEPROM must be tied
to ground.
When not grounded, the pin is HI via pullup resistor R210 and therefore
write protected. Whether or not Write Protect is provided is at the
discretion of the cape designer.

shows the format of the contents of the expansion board
EEPROM. Data is stored in Big Endian with the least significant value on
the right. All addresses read as a single byte data from the EEPROM, but
two byte addressing is used. ASCII values are intended to be easily read
by the user when the EEPROM contents are dumped.

.. _pin-usage:
Pin Usage
==========
:ref:`eeprom-pin-usage-table` shows the locations in the EEPROM to set the I/O pin usage for
the cape. It contains the value to be written to the Pad Control
Registers. Details on this can be found in section *9.2.2* of the
*TDA4VM Technical Reference Manual*, The table is left blank as a
convenience and can be printed out and used as a template for creating a
custom setting for each cape. The 16 bit integers and all 16 bit fields
are to be stored in Big Endian format.
**Bit 15 PIN USAGE** is an indicator and should be a 1 if the pin is used or 0 if it is unused.
**Bits 14-7 RESERVED** is not to be used and left as 0.
**Bit 6 SLEW CONTROL** 0=Fast 1=Slow
**Bit 5 RX Enabled** 0=Disabled 1=Enabled
**Bit 4 PU/PD** 0=Pulldown 1=Pullup.
**Bit 3 PULLUP/DN** 0=Pullup/pulldown enabled 1= Pullup/pulldown disabled
**Bit 2-0 MUX MODE SELECT** Mode 0-7. (refer to TRM)
Refer to the TRM for proper settings of the pin MUX mode based on the
signal selection to be used.
The *AIN0-6* pins do not have a pin mux setting, but they need to be set
to indicate if each of the pins is used on the cape. Only bit 15 is used
for the AIN signals.

.. _pin-usage-consideration:
Pin Usage Consideration
========================
This section covers things to watch for when hooking up to certain pins
on the expansion headers.
.. _expansion-connectors-1:
Expansion Connectors
====================
A combination of male and female headers is used for access to the
expansion headers on the main board. There are three possible mounting
configurations for the expansion headers:
* **Single** -no board stacking but can be used on the top of the stack.
* **Stacking-up** to four boards can be stacked on top of each other.
* **Stacking with signal stealing-up** to three boards can be stacked on top of each other, but certain boards will not pass on the signals they are using to prevent signal loading or use by other cards in the stack.
The following sections describe how the connectors are to be implemented
and used for each of the different configurations.
.. _non-stacking-headers-single-cape:
Non-Stacking Headers-Single Cape
=================================
For non-stacking capes single configurations or where the cape can be
the last board on the stack, the two 46 pin expansion headers use the
same connectors. :ref:`single-expansion-connector-figure` is a picture of
the connector. These are dual row 23 position 2.54mm x 2.54mm connectors.
.. _single-expansion-connector-figure:
.. figure:: images/ch08/single-expansion-connector.jpg
:width: 400px
:align: center
:alt: Fig-Single expansion connector
Fig-Single expansion connector
The connector is typically mounted on the bottom side of the board as
shown in :ref:`single-cape-expansion-connector-figure`. These are very common connectors and should be
easily located. You can also use two single row 23 pin headers for each
of the dual row headers.
.. figure:: images/ch08/proto.jpg
:width: 400px

.. _single-cape-expansion-connector-figure:
It is allowed to only populate the pins you need. As this is a
non-stacking configuration, there is no need for all headers to be
populated. This can also reduce the overall cost of the cape. This
decision is up to the cape designer.
For convenience listed in :ref:`single-cape-connectors-figure` are some possible
choices for part numbers on this connector. They have varying pin lengths and
some may be more suitable than others for your use. It should be noted, that the
longer the pin and the further it is inserted into BeagleBone AI-64
connector, the harder it will be to remove due to the tension on 92
pins. This can be minimized by using shorter pins or removing those pins
that are not used by your particular design. The first item in**Table
18** is on the edge and may not be the best solution. Overhang is the
amount of the pin that goes past the contact point of the connector on
BeagleBone AI-64

The G in the part number is a plating option. Other options may be used
as well as long as the contact area is gold. Other possible sources are
Sullins and Samtec for these connectors. You will need to ensure the
depth into the connector is sufficient
.. _main-expansion-headers-stacking:
Main Expansion Headers-Stacking
================================
For stacking configuration, the two 46 pin expansion headers use the
same connectors. :ref:`expansion-connector-figure` is a picture of the
connector. These are dual row 23 position 2.54mm x 2.54mm connectors.
.. _expansion-connector-figure:

The connector is mounted on the top side of the board with longer tails
to allow insertion into BeagleBone AI-64.
:ref:`stacked-cape-expansion-connector-figure` is the
connector configuration for the connector.

For convenience listed in *Table 18* are some possible choices for part
numbers on this connector. They have varying pin lengths and some may be
more suitable than others for your use. It should be noted, that the
longer the pin and the further it is inserted into BeagleBone AI-64
connector, the harder it will be to remove due to the tension on 92
pins. This can be minimized by using shorter pins. There are most likely
other suppliers out there that will work for this connector as well. If
anyone finds other suppliers of compatible connectors that work, let us
know and they will be added to this document. The first item in **Table
19** is on the edge and may not be the best solution. Overhang is the
amount of the pin that goes past the contact point of the connector on
BeagleBone AI-64.
The third part listed in :ref:`stacked-cape-connectors-figure` will have
insertion force issues.

There are also different plating options on each of the connectors
above. Gold plating on the contacts is the minimum requirement. If you
choose to use a different part number for plating or availability
purposes, make sure you do not select the “LT” option.
Other possible sources are Sullins and Samtec but make sure you select
one that has the correct mating depth.
.. _stacked-capes-wsignal-stealing:
Stacked Capes w/Signal Stealing
================================
:ref:`stacked-with-signal-stealing-expansion-connector-figure` is the connector configuration for stackable capes that does
not provide all of the signals upwards for use by other boards. This is
useful if there is an expectation that other boards could interfere with
the operation of your board by exposing those signals for expansion.
This configuration consists of a combination of the stacking and
nonstacking style connectors.
.. _stacked-with-signal-stealing-expansion-connector-figure:

:width: 400px
:align: center
:alt: Fig-Stacked with signal stealing expansion connector figure

.. _retention-force:
Retention Force
================
The length of the pins on the expansion header has a direct relationship
to the amount of force that is used to remove a cape from BeagleBone
AI-64. The longer the pins extend into the connector the harder it is to
remove. There is no rule that says that if longer pins are used, that
the connector pins have to extend all the way into the mating connector
on BeagleBone AI-64, but this is controlled by the user and
therefore is hard to control. We have also found that if you use gold
pins, while more expensive, it makes for a smoother finish which reduces
the friction.
This section will attempt to describe the tradeoffs and things to
consider when selecting a connector and its pin length.
.. _beaglebone-ai-64-female-connectors:
BeagleBone AI-64 Female Connectors
===================================
:ref:`connector-pin-insertion-depth` shows the key measurements used in calculating how much the
pin extends past the contact point on the connector, what we call
overhang.
.. _connector-pin-insertion-depth:
.. figure:: images/ch08/berg-stip-insertion.jpg
:width: 400px
:align: center
:alt: Fig:Connector Pin Insertion Depth
Connector Pin Insertion Depth
To calculate the amount of the pin that extends past the Point of
Contact, use the following formula:
Overhang=Total Pin Length- PCB thickness (.062) - contact point (.079)
The longer the pin extends past the contact point, the more force it
will take to insert and remove the board. Removal is a greater issue
than the insertion.
.. _signal-usage:
Signal Usage
=============
Based on the pin muxing capabilities of the processor, each expansion
pin can be configured for different functions. When in the stacking
mode, it will be up to the user to ensure that any conflicts are
resolved between multiple stacked cards. When stacked, the first card
detected will be used to set the pin muxing of each pin. This will
prevent other modes from being supported on stacked cards and may result
in them being inoperative.
In :ref:`section-7-1` of this document, the functions of the pins are defined
as well as the pin muxing options. Refer to this section for more
information on what each pin is. To simplify things, if you use the
default name as the function for each pin and use those functions, it
will simplify board design and reduce conflicts with other boards.
Interoperability is up to the board suppliers and the user. This
specification does not specify a fixed function on any pin and any pin
can be used to the full extent of the functionality of that pin as
enabled by the processor.
*DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE
BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.*
*NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.*
.. _cape-power:
Cape Power
===========
This section describes the power rails for the capes and their usage.
.. _main-board-power:
Main Board Power
=================
The :ref:`expansion-header-voltages-table` describes the voltages from the
main board that are available on the expansion connectors and their ratings.
All voltages are supplied by connector**P9**. The current ratings listed are per pin.
.. _expansion-header-voltages-table:

The *VSYS_IO_3V3* rail is supplied by the LDO on BeagleBone AI-64 and
is the primary power rail for expansion boards. If the power requirement
for the capes exceeds the current rating, then locally generated voltage
rail can be used. It is recommended that this rail be used to power any
buffers or level translators that may be used.
*DC_VDD_5V* is the main power supply from the DC input jack. This voltage
is not present when the board is powered via USB. The amount of current
supplied by this rail is dependent upon the amount of current available.
Based on the board design, this rail is limited to 1A per pin from the
main board.
The *VSYS_5V0* rail is the main rail for the regulators on the main board.
When powered from a DC supply or USB, this rail will be 5V. The
available current from this rail depends on the current available from
the USB and DC external supplies.
.. _expansion-board-external-power:
Expansion Board External Power
===============================
A cape can have a jack or terminals to bring in whatever voltages may be
needed by that board. Care should be taken not to let this voltage be
fed back into any of the expansion header pins.
It is possible to provide 5V to the main board from an expansion board.
By supplying a 5V signal into the *DC_VDD_5V* rail, the main board can be
supplied. This voltage must not exceed 5V. You should not supply any
voltage into any other pin of the expansion connectors. Based on the
board design, this rail is limited to 1A per pin to BeagleBone
AI-64.
*There are several precautions that need to be taken when working with
the expansion headers to prevent damage to the board.*
1. *Do not apply any voltages to any I/O pins when the board is not powered on.*
2. *Do not drive any external signals into the I/O pins until after the VSYS_IO_3V3 rail is up.*
3. *Do not apply any voltages that are generated from external sources.*
4. *If voltages are generated from the DC_VDD_5V signal, those supplies must not become active until after the VSYS_IO_3V3 rail is up.*
5. *If you are applying signals from other boards into the expansion headers, make sure you power the board up after you power up the BeagleBone AI-64 or make the connections after power is applied on both boards.*
*Powering the processor via its I/O pins can cause damage to the processor.*
**TODO: Add BeagleBone AI-64 cape mechanical characteristics**
.. _standard-cape-size:
Standard Cape Size
===================
:ref:`cape-board-dimensions-figure` shows the outline of the standard cape. The dimensions are in inches.
.. _cape-board-dimensions-figure:
.. figure:: images/ch08/cape-dimension.jpg
:width: 400px
:align: center
:alt: Fig: Cape board dimensions
Fig: Cape board dimensions
A notch is provided for BeagleBone Ethernet connector to stick up higher than
the cape when mounted. This also acts as a key function to ensure that
the cape is oriented correctly. Space is also provided to allow access
to the user LEDs and reset button on BeagleBone board. On BeagleBone AI-64 board
align it with the notch on the board silkscreen.
.. _extended-cape-size:
Extended Cape Size
===================
Capes larger than the standard board size are also allowed. A good
example would be the new BeagleBone AI-64 robotics cape.
There is no practical limit to the sizes of these types of boards.
The notch is also optional, but it is up to the supplier to ensure that the
cape is not plugged incorrectly on BeagleBone AI-64 such that damage would
be cause to BeagleBone AI-64. Any such damage will be the responsibility of the
supplier of such a cape to repair. As with all capes, the EEPROM is required and
compliance with the power requirements must be adhered to.
