Hello,
I try to turn a led manually on and off.
The led is connected in P9_25 that is gpio117.
So I execute the following lines in beaglebone’s terminal:
`
cd /sys/class/gpio
echo 117 > export
cd gpio117
echo out > direction
echo 1 > value
`
But the led is always on.
I measured the voltage with a digital mutimeter and it was 1.66V for both values 1 and 0.
Do you have any idea on what could be the problem?
