There is a gpio group (at least on the Jetson Nano) that appears to have no purpose.
I have my “nano” user added to that group yet still, I have to sudo to access anything in sysfs (specifically the gpio).
nano@nano-desktop:~$ cat /sys/kernel/debug/gpio cat: /sys/kernel/debug/gpio: Permission denied
Does anyone know how to fix this?
Update: okay, I CAN write/read to /sys/class/gpio/ and below. I just cannot access /sys/kernel/debug/gpio
