Hi NVIDIA,

I’m using Jetpack: Jetpack 5.1.2
Custom carrier board.
Question about DT file modification

Questions:

1. Number of files to modify, file name, and its location (directory) for my custom pinmux
2. What file(s) that needs to be converted from dts to dtb or vice versa
3. which file should be modified DT entries for MGBE (AQR113C) to enable 10G function?

Regards,

Hi netkerl,

It seems you are using the custom carrier board for AGX Orin.
Please refer to Jetson AGX Orin Platform Adaptation and Bring-Up — Jetson Linux Developer Guide documentation (nvidia.com) for your board.

You can check the flash log to know which dtb is loaded and flashed.
Or check the board config file to know which dtb is specified.

You should download the kernel source → customize for your board → build the kernel image/dtb → replace and reflash.
To download the kernel source, please refer to Kernel Customization — Jetson Linux Developer Guide documentation (nvidia.com)
