Issues with enabling GPIO Pins in Jetson Orin

Currently I am using Jetson AGX Orin and I am trying to enable a pwm pin in the Jetson 40pin header however, I am having a bit of trouble with configuring and enabling pins. When i try to configure my jetson
$ sudo /opt/nvidia/jetson-io/jetson-io.py

I get

jetson_tool
jetson_tool623×876 11.6 KB

And also when i check my
$ sudo /opt/nvidia/jetson-io/config-by-function.py

I realise my pwm pin is not enabled, is that normal?

Hi rvgroshan22,

Are you using the devkit or custom board for AGX Orin?
What’s your Jetpack version in use?

Jetson-IO is used to enable the functions like PWM, SPI, I2C, CAN…etc on the devkit.
If you want to use the pin as GPIO, please just configure it in pinmux spreadsheet and use gpiod or python script(Jetson.GPIO) to control it.

I am using a NVIDIA® Jetson AGX Orin 32GB H01 Kit from Seeed Studio
My Jetpack Version is nvidia-jetpack 5.0.2-b231
Currently Im using a custom overlay dts file

It seems a custom carrier board from Seeed Studio.

Please request your vendor for the custom BSP package of later Jetpack release like 5.1.3 or 5.1.4.

Which pin do you want to control?

Hi @rvgroshan22 ,

Have you modified the pinmux already? Can you share a couple of logs over your host device in order to get more information about your current state?

ls -lt Linux_for_Tegra/bootloader/t186ref/BCT
ls -lt *.conf Linux_for_Tegra
