I have tried to enable the GPIO pins for my system through the Kernel but I am not able to get them to work. When I try this:
echo 1 > /sys/class/gpio/export
The terminal window just closes. When using a different number such as 30, the terminal just hangs and I cannot ctrl-C it. According to everything I read, if GPIO is enabled through the kernel correctly, you should be able to export a GPIO port in sysfs and then you will see each GPIO port in /sys/class/gpio. Example /sys/class/gpio/gpio0 and then you should be able to send it values. I am using Debian 3.11.4.
