I am using a Jetson AGX Orin and trying to generate a PWM signal on physical Pin 18 (PWM5). I enabled PWM5 through Jetson-IO and rebooted the system, but I am unable to observe any PWM output on Pin 18. As a comparison, I configured physical Pin 13 (PWM8) using the same procedure, and PWM generation works correctly on that pin. Could someone help verify whether any additional configuration is required for PWM5 on Pin 18 or if there are known issues with this pin?

Hi joseph.thomas,
Are you using the devkit or custom board for AGX Orin?
What’s the Jetpack version in use?
Could you share the steps how did you generate PWM output after configuring the pinmux through jetosn-io tool?
You can also refer to Unable to generate PWM with Nvidia Jetson AGX Orin Development Kit - #6 by KevinFFF for the steps to verify PWM on AGX Orin.
