Need UART connections for BCF_RXD/BCF_TXD
Created by: jadonk
The last revision worked, but the latest revision has the pins connected to only a PRU UART. That cannot work. They need to be on a main or wakeup UART.
Please prefer connections specified by https://elinux.org/Beagleboard:BeagleBone_cape_interface_spec#UART.
