RE: UART2 and config-pin/Debug Assistance Maybe?


How would one debug why config-pin is not working on the BBGW…

I have power to a module w/ LED showing status but I think config-pin is going through a reboot as I type this message…

So, I was thinking that if someone knew of a workaround for using UART2 w/ Adafruit_BBIO.UART as UART and pyserial, someone could jump in here.


Here is the error I get which astounds me for some reason.

Or…if you are tired of, please see below:

py_setup_uart(UART2): set_pin_mode() failed for pin=P9_22Traceback (most recent call last):
  File "./", line 7, in <module>
ValueError: Set pin mode failed for uart channel.

I am basically just working w/ a GPS SIM28.


P.S. I added the BB-UART2-00A0.dtbo in /boot/uEnv.txt like recommended under its respective place.
