Cannot Use initrd Flash with Orin Nano

Issue Overview

Users have reported difficulties when attempting to flash the Nvidia Jetson Orin Nano development board with Jetson Linux version 36.2, specifically when enabling the root filesystem (rootfs) A/B configuration. The primary symptom is an error message displayed on the monitor connected to the development board, stating:

“The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again.”

This issue occurs during the flashing process, particularly when following instructions from the official Nvidia documentation for flashing with rootfs A/B enabled. In contrast, users have noted that flashing without this configuration (the default case) is successful.

The hardware setup includes a Jetson Orin Nano development board equipped with a 128GB SSD, which is confirmed to have sufficient capacity for the installation. The frequency of this issue appears to be inconsistent among users, with some successfully flashing while others encounter errors.

The impact of this problem significantly affects user experience as it prevents successful installation and may lead to frustration and delays in project development.

Possible Causes

• Hardware Incompatibilities or Defects: While the SSD capacity is adequate, other hardware components may not be fully compatible or could be defective, leading to installation failures.

• Software Bugs or Conflicts: There may be bugs in the Jetson Linux version 36.2 that affect the flashing process, particularly when enabling rootfs A/B configuration.

• Configuration Errors: Users might be misconfiguring settings related to the flashing process, leading to errors during installation.

• Driver Issues: Outdated or incompatible drivers could prevent proper communication between the development board and the flashing tools.

• Environmental Factors: Power supply issues or overheating could potentially disrupt the flashing process.

• User Errors or Misconfigurations: Incorrect command execution or misunderstanding of the documentation could lead to errors during installation.

Troubleshooting Steps, Solutions & Fixes

1. Verify Command Syntax:

   • Ensure that you are using the correct command as specified in the Nvidia documentation for enabling rootfs A/B configuration.
   • Example command:

     $ sudo tools/l4t_create_default_user.sh -u test -p test
     

2. Skip OEM Configuration:

   • As suggested by other users, try skipping OEM configuration before attempting to flash again. This can sometimes resolve issues related to hanging during setup.
   • Follow instructions from this link: Skipping OEM Configuration.

3. Check System Logs:

   • After encountering the error message, check system logs for more detailed error messages that can provide insight into what went wrong.
   • Use commands like:

     $ dmesg | less
     $ journalctl -xe
     

4. Test Different Flashing Methods:

   • If you continue to face issues, consider trying different methods of flashing, such as using a different USB port or cable, or even a different host machine if available.

5. Update Drivers and Firmware:

   • Ensure that all necessary drivers and firmware are up-to-date before attempting another flash.
   • Check Nvidia’s official site for any updates related to Jetson Linux and relevant tools.

6. Perform Clean Installation:

   • If previous attempts have failed, consider performing a clean installation by formatting the SSD and starting from scratch.

7. Consult Community Forums:

   • Engage with community forums for additional support and shared experiences from other users who may have faced similar issues.

8. Document Findings:

   • Keep track of any changes made during troubleshooting and their outcomes to help identify patterns or successful solutions.

If multiple users report success with a particular solution (e.g., skipping OEM configuration), it should be highlighted as a recommended approach for others facing similar issues. Further investigation may be required if problems persist despite following these steps, particularly regarding hardware compatibility or deeper software bugs.
