We have been having issues with GPIO ever since we upgraded to the latest version of JetPack. Originally the error was that it couldn’t detect the board so I added an environment variable JETSON_MODEL_NAME=JETSON_ORIN_NANO which stopped the bugs, but now the Jetson.GPIO library in python does nothing. The only pin I got working is reading input from pin 40 by wiring it to either 5V/GND on the board. The gpio output doesn’t seem to work on that pin however, as a simple led blink script doesn’t seem to do anything. Best I could do is just connect the led to 5V to get it to turn on. Nothing else seems to work as far as I can tell.
Someone else on our team linked to this post, which seems to describe our problem very well. I will get back after going through the steps described in that problem. Hopefully, it ends up being helpful.
Hi sovereignshahid,
Are you using the devkit or custom board for Orin Nano?
What’s the Jetpack version in use?
Have you configured the pinmux before use the pin?
Please apply the patch from 40hdr - SPI1 gpio padctl register bit[10] effect by gpiod tools in JP6 - #20 by KevinFFF if you want to control GPIO with JP6.x.
