Issue with PWM Pins on Jetson Orin Nano GPIO – Pins 33 and 32 Not Functioning

Hello Everyone,
I’m currently facing an issue with my Jetson Orin Nano GPIO, specifically related to PWM pins. I have installed the latest Jetson.GPIO library and verified the configuration in the gpio_pin_data.py file, following the instructions provided in the GitHub repository [update pwm pin by anhmiuhv · Pull Request #88 · NVIDIA/jetson-gpio · GitHub].

However, I am unable to utilize PWM functionality on pins 33 and 32. Strangely, pins 15 are working correctly.

Here are the steps I’ve taken so far:

  1. Installed the latest Jetson.GPIO library.
  2. Checked the gpio_pin_data.py file for correct configuration.

Despite these steps, I am still facing the issue. Pins 33 and 32 do not seem to be functioning as expected.

Has anyone encountered a similar problem or have insights into how to resolve this issue? I would greatly appreciate any guidance or suggestions.

Thanks!

Hi,
Have you tried this solution? Jetson.GPIO lib - PWM not working on Orin Nano Dev Kit. They propose a patch for gpio_pin_data.py

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

What do you mean with not working? Then are you able to use them in sysfs?
What does debugfs show for these two pins?
