Problem with upgrading jetpack 6.0 to jetpack 6.1

Issue Overview

Users have reported significant issues after upgrading their Nvidia Jetson Orin Nano Dev board from JetPack 6.0 to JetPack 6.1. The primary symptoms include:

• JetPack Not Installed: After the upgrade, the jtop utility indicates that while libraries have been upgraded, it also states that JetPack is not installed.

• Crashes in Nsight Compute: The new version of Nsight Compute (2024.3.1) consistently crashes when running CUDA examples that previously worked fine with the older version (2023.2.2). Recompiled CUDA examples run without issue, but Nsight Compute fails at the end of execution.

• Rollback Concerns: Users are seeking methods to revert to the previous JetPack version due to these issues, but have encountered limitations in doing so.

The problems occur during the use of the Jetson board for educational purposes, affecting teaching and practical demonstrations.

Possible Causes

Several potential causes for these issues have been identified:

• Software Bugs: The upgrade to JetPack 6.1 may contain unresolved bugs that affect compatibility with existing applications and tools like Nsight Compute.

• Driver Issues: Incompatibilities between the updated libraries and existing drivers could lead to crashes and misreported installations.

• Configuration Errors: Incorrect configurations during or after the upgrade process may result in software not recognizing the installed JetPack version.

• Environmental Factors: External factors such as power supply inconsistencies or thermal issues could exacerbate software stability problems.

• User Errors: Missteps in the upgrade process or commands issued may lead to incomplete installations or corrupt configurations.

Troubleshooting Steps, Solutions & Fixes

To address the issues experienced after upgrading to JetPack 6.1, users can follow these troubleshooting steps and potential solutions:

1. Verify Installation:

   • Run the following command to check the current JetPack version:

     cat /etc/nv_tegra_release
     

   • Ensure that the output matches expected values for JetPack 6.1.

2. Reinstall JetPack:

   • If JetPack is not recognized, attempt to reinstall it using:

     sudo apt update
     sudo apt install nvidia-jetpack
     

3. Check for Compatibility Issues:

   • Review release notes for both JetPack 6.0 and 6.1, focusing on any changes that might affect Nsight Compute or CUDA applications.

4. Run Nsight Compute with Debugging Options:

   • Use debugging flags when running Nsight Compute to capture more detailed logs about crashes:

     nsight-compute --debug
     

5. Consider Flashing Previous Release:

   • While rolling back directly is not supported, reflashing the board might restore functionality:
     • Follow instructions from Nvidia’s documentation on flashing previous releases, ensuring all necessary backups are made prior.

6. Monitor System Resources:

   • Use jtop or similar tools to monitor system resources during execution to identify any resource constraints leading to crashes.

7. Engage with Community Support:

   • Post detailed logs and error messages on forums or Nvidia support channels for community assistance.

8. Best Practices for Future Upgrades:

   • Always back up critical data and configurations before performing upgrades.
   • Test upgrades in a controlled environment if possible before deploying in production or educational settings.

9. Documentation and Updates:

   • Regularly check Nvidia’s official documentation for updates regarding known issues and fixes related to JetPack versions.

By following these steps, users can diagnose and potentially resolve issues stemming from the upgrade process while minimizing disruptions in their work or teaching environments.
