problem: why it dont work
opretion:

  1. modify Jetson_Orin_NX_and_Orin_Nano_series_Pinmux_Config_Template.xlsm，generate dtsi file

Hi gengqi_yz,

Please refer to the following steps to verify PWM on Orin Nano devkit.
Unable to generate PWM with Nvidia Jetson AGX Orin Development Kit - #6 by KevinFFF

  1. By default in simple_pwm.py, it will perform PWM signal from pwm5(PIN33)

  2. but i modify simple_pwm.py,it does not work in pwm7(pin32)

  3. If I want to change the system image, I need to modify which files to make it successful, Instead of using Python script

hi KevinFFF,

Based on the examples you give, I still have the following questions

Please configure the pwm7 through Jetson-IO. (i.e. enable pwm7 in jetson-io and reboot to apply the change)

Yes, I did this, but there is still this problem

Sorry for the late response.
Is this still an issue to support? Any result can be shared?

Hi gengqi_yz,

Do you mean that you would still hit “Channel 32 is not a PWM” issue with simple_pwm.py after you use Jetson-IO to enable it?

11

yes, i configure channnel 32 , then reboot, but it does not work

It seems not the expected result to me.
Coud you also verify with the latest Jetpack 5.1.3 (R35.5.0)?
