But on gpiod examples on python, I have to use a gpio chip parameter, but I don’t know what is that, I can’t find any documentation about this on solidrun web. How can i do this?
Due to board design changes the now mikrobus GPIO is allocated to the LEDs group which is why you are getting the error that the resource is busy. I will push patches to fix this oversight.
It is possible the Debian kernel isn’t building or loading the leds module, which would allow the GPIOs to work properly. Regardless I will fix it properly in the device-tree.
