Hello everyone,
I would like to use GPIO on the motherboard in order to control them. I'm actually using a Debian on this card, and when I'm in the next folder : ls /sys/class/gpio/
I only have 2 others folders: export and unexport.
Next, when I want to export a pin like this: echo 24 >/sys/class/gpio/export (I have tested a lot of numbers)
It seems impossible to access it because I got a permission denied, by the OS, although I configured the BIOS and enable the access to all GPIO.
Do you have any solution in order to control GPIO on a Debian please ?
