Hi all. I can not get work gpio.
In my case this is not working, I do not see any change on the physical GPIO pin
echo 47 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio47/direction
echo 1 > /sys/class/gpio/gpio47/value
Some additional details below. What can be wrong?
Thanks for the Link.
I found problem, The Controll Mux register for specific pins had incorrect values.
The pins was set for peripheral purpose instead of gpio purpose (MUX_MODE)
