Well, thats pretty recursive, I guess.
pi@raspberrypi:~ $ cat /sys/class/gpio/gpiochip0/device/gpio/gpiochip0/device/gpio/gpiochip0/device/gpio/gpiochip0/device/gpio/gpiochip0/
base device/ label ngpio power/ subsystem/ uevent
And you can go on, and on, and on like that.
What's wrong with you RaspberryPi?
It's a fresh raspbian installierbar, with the only Addition of 1wire and snmp.
I'd expect /sys/class/gpio/gpio<pinnumber>/value there.
@alsternerd I'm not sure what you are trying to do, but did you call "echo «pinnumber» > /sys/class/gpio/export" beforehand?
And maybe you need to change /sys/class/gpio/gpio0/direction to "in" or "out", too.
The package "sysfsutils" can help to make this permanent and assign user permissions, if needed.
