How to get GPIO running using the new UP Squared Pro?
I followed the instructions from here but without any success to get the GPIO running with mraa under Ubuntu 18.04.5 (server) including the upboard-extras.
Here some system outputs:
Linux lidarbox 5.4.0-1-generic #0~upboard2-Ubuntu SMP Sun Oct 25 14:06:23 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
[ 0.306554] pinctrl core: initialized pinctrl subsystem
Version v2.0.0 on Unknown platform
I've also tried to run mraa as sudo with no success.
