Hello,
I am using the python jetson-gpio library on a jetson xavier nx. Launching any of the files inside the samples folder, I got the fallowing error message

amr@moto:~/Downloads/jetson-gpio/samples$ sudo python3 test_all_pins.py
Testing pin 7 as OUTPUT; CTRL-C to test next pin
Traceback (most recent call last):
File “test_all_pins.py”, line 89, in
GPIO.setup(pin, GPIO.OUT)
File “/usr/local/lib/python3.7/dist-packages/Jetson.GPIO-2.1.3-py3.7.egg/Jetson/GPIO/gpio.py”, line 360, in setup
File “/usr/local/lib/python3.7/dist-packages/Jetson.GPIO-2.1.3-py3.7.egg/Jetson/GPIO/gpio.py”, line 155, in _do_one_channel

Exception: tegra194-gpio: No such gpio device registered

Any suggestion to solve the issue is appreciated
Thanks

Sorry for the late response.
Is this still an issue to support? Any result can be shared?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Are you uisng the devkit or custom board for Xavier NX?
What’s your Jetpack version in use?

Are you trying to configure PIN7?
