Hello; I was testing an Nvidia Jetson nano dev board with Fedora 33 and 34 (I have 2 boards) and I wasn't able to control gpio pins via "libgpiod"(python). Because I couldn't find a proper gpio pin "gpiochip0" and didn't even able control LED as well.I checked examples(python code ) and tried with command line tools but no luck. Any suggestions? Thank you. Regards ---------------------- Onuralp SEZER Fedora Ambassadors EMEA Member / Turkey
