Orin nano JetPack 5.1.1 pinmux problem

[gengqi_yz]

device: orin nano 8gb devkit
function: modify gpio07 to pwm
problem: why it dont work
opretion:

1. modify Jetson_Orin_NX_and_Orin_Nano_series_Pinmux_Config_Template.xlsm，generate dtsi file
   
   
2. modify jetson-orin-nano-devkit.conf, copy dtsi to bootloader/t186ref
   
3. modify devicetree file
   
4. flash to device
5. start device

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

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

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?

[gengqi_yz]

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

[KevinFFF]

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