Hi everyone, I'm using BBxM Rev C2 board and trying to read GPIO_159 that is in expansion header. I successfully used it as output(Turn On LED and TURN OFF LED). But I can't read anything on this port.
I used this steps; cd /sys/class/gpio/ echo 159 > export cd /sys/class/gpio/gpio159 echo "in" > direction cat value // this always response me "0" zero. I'm normally using pull up button so that it has high level when it's not pressed. But I always take "0" value when I write "cat value" command on terminal. Has anybody idea?
