Exception: Could not determine Jetson model

Installation of adafruit’s adafruit-blinka has a Jetson.GPIO dependency which was downloaded and installed using pip3.

Error returns ‘Could not determine Jetson model’ from gpio_pin_data.py.

My /proc/device-tree/compatible looks like: raspberrypi,3-model-b-plus^@brcm,bcm2837^@

Question: Does jetson-gpio not support raspberry pi hardware? Can I manually modify my compatible file to include a compatible board, and if so which one? Thanks

I walked through the trace and it was just odd that the init.py in RPi/GPIO was importing Jetson.GPIO. I double checked the source and there wasn’t a match despite my system telling me that the RPi.GPIO version was the same as the source. So uninstalled RPi.GPIO and reinstalled and it works!

Thanks for the tip regarding different platform supports!

Now for some motor tinkering >_>

I used that Ubiquity image on a Pi 3B+ and still don’t see Jetson.GPIO being installed automatically when adafruit-blinka is installed using pip. I’ve run out of things to try to reproduce your issue.
