GPIO of NOAH V2 Motherboard

(1/1)

toto_toto:
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 ?
