Orin nano JetPack 5.1.1 pinmux problem

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

  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


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
