Jetson Orin Nano Ubuntu 20.04 Upload Error

Issue Overview

Users are experiencing issues while attempting to install Ubuntu 20.04 on the Jetson Orin Nano Developer Kit. The main symptoms include failure to load the user interface after installation attempts, with the system getting stuck at the boot menu displaying an error labeled "startup.nsh." The problem arises during the setup phase when users try to flash the OS using either the Nvidia SDK or an SD card method. The board is reportedly not detected by the SDK, and the boot process halts, leading to frustration and hindering development activities, especially for those working with ROS codes that require this specific OS version. This issue appears to be consistent among multiple users, significantly impacting their ability to utilize the device effectively.

Possible Causes

• Hardware Incompatibilities or Defects: The Jetson Orin Nano may have compatibility issues with certain hardware configurations or defects in the board itself.
• Software Bugs or Conflicts: There might be unresolved bugs in the JetPack version being used, particularly if using a developer preview version.
• Configuration Errors: Incorrect settings during the flashing process, such as failing to put the board into recovery mode, can lead to installation failures.
• Driver Issues: Outdated or incorrect drivers may prevent proper communication between the SDK and the hardware.
• Environmental Factors: Power supply issues or overheating could disrupt normal operation during flashing.
• User Errors or Misconfigurations: Improperly following installation steps or using incorrect commands can lead to failures.

Troubleshooting Steps, Solutions & Fixes

1. Verify Board Connection:

   • Ensure that all connections are secure and that you are using a compatible power supply.

2. Force Recovery Mode:

   • To put the board in recovery mode, connect pins 9 and 10 (located under the module, not on the 40-pin header) before powering on the device.

3. Using SDK Manager:

   • Launch Nvidia SDK Manager and select "Manual Setup" when prompted.
   • If the board is not detected, ensure it is in recovery mode and try reconnecting it.
   • If errors occur during flashing, use the "EXPORT LOGS" feature to gather diagnostic information.

4. Re-flash SD Card:

   • Use a reliable image of JetPack 5.x instead of JetPack 6 if experiencing issues with developer previews.
   • Follow instructions carefully for flashing an SD card as this method is not officially supported for Jetson devices.

5. Check for Software Updates:

   • Ensure you are using the latest version of JetPack compatible with your board. Consider downgrading if issues persist with newer versions.

6. Testing Different Configurations:

   • Try different SD cards or USB drives for flashing.
   • Test with another computer to rule out host-related issues.

7. Seek Community Support:

   • Engage in forums like NVIDIA Developer Forums for additional troubleshooting tips from other users who may have faced similar issues.

8. Best Practices for Future Installations:

   • Always back up your configuration before making changes.
   • Keep your development environment updated and check compatibility before upgrading software.

9. Documentation & Resources:

   • Refer to NVIDIA’s official documentation for detailed instructions on flashing and setup procedures.
   • Ensure you have access to all necessary drivers and updates before starting installation.

10. Unresolved Issues:

    • If problems persist after following all troubleshooting steps, consider reaching out directly to NVIDIA support for further assistance.

By following these steps, users should be able to identify and rectify issues related to installing Ubuntu 20.04 on their Jetson Orin Nano Developer Kit effectively.
