Issue in General Purpose Output Pin MRAA 35 & MRAA 38

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.

Thanks for update regarding PC12.

Once again, I will check regarding PC18 (mraa pin no.38) and update you.
