It seems like my Jetson nano module is having issues communicating with the carrier board.
Someone (not me) carelessly plugged in an external 5V 2A power supply to a +5V gpio out pin on the jetson nano.
The system instantly crashed and powered off.
I was able to boot up again, but now the GPIO is not functioning and I am getting warning that carrier board is not recoginzed when importing Jetson.GPIO

However, my USB works, my camera works, HDMI works. It seems like only GPIO is not working.
Also worth noting, my carrier board only has one slot for MIPI camera. I noticed the picture on the website has two lots for MIPI camera. Could this be causing the issue?
Do I have an older carrier board?
