I must be missing step in the documentation.
I have installed the Macarthur, it did not light the LEDS until I mounted it on the longest legs.
Now the LEDs show for 12v and 5v and it powers the RPI5
So I want to follow the steps to program GPIO 21 for shutdown.
The GPIO map shows this pin as green, and if I try to select any green pins in the GPIO config, it says 'you cannot select this gpio to do this job'
where do I tell it that the Macarthur Hat is there?
Do I have to enable the UART3 somewhere? the notes do not follow a logical steps for me.
Looks like i had enabled all the UARTS which had reserved pins, plus I got confused on the GPIO map between actual GPIO 21 on pin 40 (right one) and the mapping of GPIO 9-21. Seems ok now
