Hi,
i am working on a project on the Nvidia Jetson Orin Nano Dev Kit and suddenly the GPIOs stopped working. I created a C Program that used libgpiod to toggle the GPIOs embedded in the CSI Connector and everything worked fine. Then I wanted to change the GPIO and use Pin 7 of the 40 Pin Header. When probing the pin, i saw no changes. Then I tried Pin 12 and this also did not worked. Then I switched back to the first GPIO that i was using successfully, only to notice that its now also not working.
I also tried to use Jetson.GPIO in Python to see if i could get the GPIOs to toggle from there but this also wasnt working.
When I start my Program and use the gpioinfo command, i can see that the correct GPIO is being used by my program.
Thats why I think it isnt a software problem. I am not 100% sure, but maybe when I was probing the 40 Pin Header i shorted some pins on accident with my probe. I am also not 100% sure if i smelled something burned, but i could be the case. Apart from the GPIOs, everything on the Jetson works fine.
Could someone maybe point me in a direction, how i could solve this problem or maybe tell me, which parts/ics/… i could have accidently destroyed by probing
Best regards,
Tim
