I try to poll for gpio new data, but it does not work...
I based my code on this gpio test app:
developer.ridgerun.com/wiki/index.php/Gpio-int-test.c
details:
gl-ar150, gpio8, it is bound, so i unbind + assign it with:
echo "gpio-keys-polled" > /sys/bus/platform/drivers/gpio-keys-polled/unbind
echo 8 > /sys/class/gpio/export
echo in > /sys/class/gpio/gpio8/direction
then i can read it with:
cat /sys/class/gpio/gpio8/value
the value changes when i press the button.

when I run this test app, I get no output.
I tried some advises like read/seek before poll, no good
ideas?
