Hi, I have trouble getting PWM output on Pin 32 on the Xavier NX dev kit. I configured the Pin 32 and Pin 33 with /opt/nvidia/jetson-io/jetson-io.py Pin 33 works as expected using the jetson-gpio library. But Pin 32 seems half on and sometimes on in an erractic pattern. Also when checking the je…

hello robo_chris82, you may check the board configuration files, could you please share the results of pinmux.0x0243d030=. BTW, according to Topic 121192 , PWM is works by updated pinmux table on Xavier NX.

PWM works on pin 33 but not pin 32 on Dev Kit

hello robo_chris82,

please refer to Jetson Xavier NX GPIO Header J12 PINOUT.
you should also check pinmux spreadsheets, pin-32 is by default configure as GPIO pin, please also refer to pinmux changes to configure pin32 as PWM pin,
thanks
