Jetson Orin Nano: QSPI Update Issues and Model Confusion

Issue Overview

Users of the Jetson Orin Nano DevKit B01 have reported difficulties when attempting to update the QSPI (Quad Serial Peripheral Interface) firmware. Specifically, an error occurs during the installation of the nvidia-l4t-jetson-orin-nano-qspi-updater package, stating that it is only applicable for DevKits labeled as 0005. This issue arises despite the user’s device being identified as a 0003 model (JON 8GB), leading to concerns about reduced functionality and compatibility. The problem manifests during setup, particularly when users try to utilize the SDK Manager for flashing or updating the device, which fails to recognize the board correctly. Users have noted that this issue significantly hampers their ability to utilize the board effectively, particularly for development purposes.

Possible Causes

1. Model Confusion: The discrepancy between model numbers (0003 vs. 0005) suggests that users may be using a module that lacks certain capabilities present in the intended DevKit configuration.
2. Hardware Limitations: The Jetson Orin Nano models differ in hardware specifications, specifically regarding eMMC and QSPI usage, which could explain the update failure.
3. Software Bugs: The SDK Manager may have bugs or compatibility issues with certain versions of Ubuntu or JetPack, leading to detection failures.
4. Configuration Errors: Incorrect configurations during initial setup or flashing processes could prevent successful updates.
5. Driver Issues: Outdated or incompatible drivers may hinder software recognition of hardware components.
6. User Misconfiguration: Users may not be following the correct procedures for entering recovery mode or flashing updates.

Troubleshooting Steps, Solutions & Fixes

1. Verify Model Number:

   • Check your device’s model number using jtop or similar tools to confirm if it is indeed a 0003 model.

2. Use Correct Software Version:

   • If you are using JetPack 6.x, consider reverting to JetPack 5.x as it is more stable and recommended for initial setups.

3. Enter Recovery Mode:

   • To place your Jetson Orin Nano into recovery mode:
     • Short pins 9 and 10 on the module while powering on.
     • Ensure you follow correct pin mapping; consult documentation if unsure.

4. Flashing Procedure:

   • Use the following command to flash the QSPI target:

     sudo ./flash.sh jetson-orin-nano-devkit-qspi mmcblk1p1
     

   • Ensure you have connected your device correctly to your host machine.

5. SDK Manager Usage:

   • Launch SDK Manager and ensure it recognizes your device in recovery mode.
   • If it fails to detect, try different USB ports or cables.
   • Export logs from SDK Manager if errors occur during flashing.

6. Driver Updates:

   • Ensure all drivers are up-to-date by checking NVIDIA’s official site for any necessary updates related to your model.

7. Consult Documentation:

   • Refer to NVIDIA’s developer documentation for specific instructions related to your model and firmware updates.

8. Community Support:

   • Engage with community forums for additional insights or similar experiences from other users.

9. Best Practices for Future Prevention:

   • Regularly check for updates on both software and hardware compatibility before performing installations.
   • Maintain a backup of configurations before making significant changes.

10. Unresolved Aspects:

    • Users have noted ongoing confusion regarding the differences in functionality between models 0003 and 0005, indicating a need for clearer documentation from NVIDIA regarding these distinctions.

By following these troubleshooting steps, users can better diagnose and potentially resolve issues related to their Jetson Orin Nano DevKit while also gaining a clearer understanding of their specific hardware capabilities and limitations.
