I'm having some trouble getting my GPIOs to behave as I'd like. I don't know if my overlay is causing problems, or something else (it's here: http://pastebin.com/JqE4emX3). But right now, I can't use sysfs to write a value to a GPIO:
# echo 115 > /sys/class/gpio/export # echo out > /sys/class/gpio/gpio115/direction # cat /sys/class/gpio/gpio115/value 0 # echo on > /sys/class/gpio/gpio115/value bash: echo: write error: Invalid argument This is true regardless of whether or not I load my overlay. My base dtb looks like this: http://pastebin.com/Wja7ZQRk This stuff used to work, so I may just be overlooking something, but I'm not 100% sure. -- Rick Mann [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
