I need to control some GPIO pins on the ATSAMA5D31 evaluation kit with a normal non-root user. Therefore I must change the file permission in for instance /sys/class/gpio.
I found in the Raspberry Pi forum http://www.raspberrypi.org/phpBB3/viewt ... =29&t=9667 how this could actually be done using udev rules like this:
SUBSYSTEM=="gpio", ACTION=="add", PROGRAM="/bin/sh -c 'chown -R pi:pi /sys%p'"
But it doesn't work here. The permissions are still root:root.
I also tried to set the correct permissions using a init script. This works, but is IMO not very elegant.
Could you please show me a way how to do this correctly e.g. via udev rules?
