Custom Platform: Pointing Files to board.conf for Nvidia Jetson Orin Nano

Issue Overview

Users are experiencing difficulties in configuring their Nvidia Jetson Orin Nano development board, specifically in pointing certain files to the board.conf file. This issue appears to be related to the setup process, particularly when using a custom board configuration. The problem impacts the ability to properly configure the board, which is crucial for its functionality and performance.

Possible Causes

1. Incorrect Board Configuration: Users may be attempting to use an inappropriate configuration file for their specific Jetson Orin Nano setup.

2. Custom Board Usage: The issue might arise when users are working with a custom board instead of the standard devkit, requiring different configuration steps.

3. Jetpack Version Incompatibility: The version of Jetpack in use might not be compatible with the current board configuration or setup process.

4. Lack of Understanding: Users may not be familiar with the correct procedure for modifying the board configuration files, leading to confusion in the setup process.

Troubleshooting Steps, Solutions & Fixes

1. Identify Board Type and Jetpack Version:

   • Determine whether you are using the devkit or a custom board for Orin Nano.
   • Check your current Jetpack version.

2. Locate Correct Configuration File:

   • If using the devkit, navigate to the <Linux_for_Tegra> directory.
   • Use the jetson-orin-nano-devkit.conf file as your board config.

3. Modify Configuration File:

   • Open the jetson-orin-nano-devkit.conf file in a text editor.
   • Locate the following lines:

     PINMUX_CONFIG="tegra234-mb1-bct-pinmux-p3767-dp-a03.dtsi";
     PMC_CONFIG="tegra234-mb1-bct-padvoltage-p3767-dp-a03.dtsi";
     

   • Replace these lines with your newly generated dtsi files.

4. Custom Board Configuration:

   • If using a custom board, you may need to create a new configuration file based on the jetson-orin-nano-devkit.conf.
   • Modify the file to match your custom board’s specifications.

5. Verify File Paths:

   • Ensure that the paths to your new dtsi files are correct in the modified configuration file.
   • Double-check for any typos or incorrect directory structures.

6. Apply Changes:

   • Save the modified configuration file.
   • Use this file when flashing or configuring your Jetson Orin Nano board.

7. Consult Official Documentation:

   • If issues persist, refer to the official Nvidia Jetson documentation for more detailed instructions on custom board configurations.

8. Seek Community Support:

   • If the problem remains unresolved, consider posting a detailed description of your setup and the steps you’ve taken in the Nvidia Developer Forums for further assistance.
