How to get GPIO running using the new UP Squared Pro?

datachaos

Hello,

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:

uname -a:
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

dmesg|grep pinctrl:
[ 0.306554] pinctrl core: initialized pinctrl subsystem

mraa-gpio list:
Version v2.0.0 on Unknown platform

mraa-gpio list
No Pins

I've also tried to run mraa as sudo with no success.

Update: Using the tool gpiod I can retrieve following data.

gpiodetect:

gpiochip2 [INT3452:02] (47 lines)
gpiochip3 [INT3452:03] (43 lines)
gpiochip4 [Raspberry Pi compatible UP GPIO] (28 lines)
