I test General Purpose Outputs MRAA Pin numbers 35 to 41, 45 to 47, 52 and 53. I connect 1K resistor and LED for output testing.
I take below reference command for testing above all pins.
echo 77 > /sys/class/gpio/export
echo out > /sys/class/gpio/PC13/direction
echo 1 > /sys/class/gpio/PC13/value
echo 0 > /sys/class/gpio/PC13/value.
I faced issue in MRAA Pin number 35 and Pin number 38. Output not getting on and off for MRAA Pin number 35 and Pin number 38.
mraa pin no.35 is PC12 is connected to User switch(SW1) and mraa pin no.38 is PC18 is connected at expansion header pin no.38. Please check accordingly.
Thanks for update regarding PC12.
Once again, I will check regarding PC18 (mraa pin no.38) and update you.
