How to Enable GPIO7 and GPIO14 as PWM8 and PWM7 on Xavier-Nx module

Hi sgamu,
Can you please give this experiment results to check if pin is actually toggling when it is GPIO:

  1. Do not use pin as PWM, keep it gpio
  2. short Pin 31 and 32 on 40-pin header
  3. echo 424 > /sys/class/gpio/export
  4. echo 416 > /sys/class/gpio/export
  5. echo out > /sys/class/gpio/gpio416/direction
  6. echo in > /sys/class/gpio/gpio424/direction
  7. echo 1 > /sys/class/gpio/gpio416/value
  8. cat /sys/class/gpio/gpio424/value
    ##measure voltage at pin 32, it should be 3.3V
  9. echo 0 > /sys/class/gpio/gpio416/value
  10. cat /sys/class/gpio/gpio424/value
    ##check voltage at pin 32, it should be 0V
    Repeat from step 7 for 3-4 times.
    Let me know the results.
