At first...I want to write GPIO number to /sys/class/gpio/export. So, I try command "sudo echo 38 > /sys/class/gpio/export".
But I get error "Permission denied". Why? And what should I do for outputing to GPIO pins? I cannot understand why super user can't write export file... -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
