Flashing a Jetson Orin Nano 4G NVMe with a Custom Image File

Issue Overview

Users are experiencing difficulties when attempting to flash a Jetson Orin Nano Developer Kit with a custom image file, specifically a .img file derived from another Jetson Orin Nano. The issue arises during the flashing process, where users report that the operation consistently fails when using the NVIDIA SDK Manager. The context of the problem typically involves users who are new to the Jetson platform and may not be familiar with the necessary steps or terminology required for successful flashing. The hardware in question is the Jetson Orin Nano 4G model, and the host system is running Ubuntu 20.04.6 LTS. The frequency of this issue appears to be common among new users, significantly impacting their ability to utilize the device effectively.

Possible Causes

1. Hardware Incompatibilities or Defects: If there are issues with the hardware itself, such as faulty NVMe connections or power supply problems, this could lead to flashing failures.
2. Software Bugs or Conflicts: The SDK Manager or other software components may have bugs that affect the flashing process.
3. Configuration Errors: Incorrect settings during the flashing setup can prevent successful completion.
4. Driver Issues: Outdated or incompatible drivers may hinder communication between the host PC and the Jetson board.
5. Environmental Factors: Power supply inconsistencies or overheating could disrupt the flashing process.
6. User Errors or Misconfigurations: New users may not follow the correct steps for flashing or may misinterpret instructions.

Troubleshooting Steps, Solutions & Fixes

1. Verify Hardware Setup:

   • Ensure that all connections are secure and that the Jetson Orin Nano is powered correctly.
   • Check that the NVMe drive is properly installed and recognized by the system.

2. Use Correct Flashing Method:

   • Follow these steps to flash using SDK Manager:
     • Connect your Jetson Orin Nano to your host PC via a USB Type-C cable.
     • Put the board into Recovery Mode by shorting pins 9 and 10 on the button header while powering on.
     • Launch SDK Manager and select "Jetson Orin Nano Developer Kit" as your target hardware.

3. Flashing Process:

   • In SDK Manager, select only "Jetson OS" under Target Components for a clean installation.
   • Review and accept all license agreements before proceeding.

4. Check for Logs:

   • If flashing fails, use the "EXPORT LOGS" feature in SDK Manager to gather diagnostic information.
   • Analyze logs for specific error messages that could indicate what went wrong.

5. Alternative Flashing Method:

   • As an alternative to SDK Manager, consider using command-line tools for flashing if you are comfortable with terminal commands:

     sudo ./flash.sh jetson-orin-nano mmcblk0p1
     

   • Ensure you replace mmcblk0p1 with your actual target device.

6. Firmware Update:

   • Make sure your Jetson Orin Nano has the latest firmware installed. If not, follow instructions in the user guide to update it.

7. Consult Documentation:

   • Refer to NVIDIA’s official documentation for detailed guidance on flashing procedures and troubleshooting tips:
     • Jetson Orin Nano Developer Kit User Guide
     • NVIDIA SDK Manager Documentation

8. Best Practices:

   • Always use a reliable power source rated for your device (9-19V for Orin Nano).
   • Avoid using developer preview versions of JetPack unless you are experienced, as they may contain unresolved bugs.

9. Community Support:

   • Engage with NVIDIA forums or community discussions for additional support and shared experiences from other users who faced similar issues.

If these steps do not resolve the issue, further investigation into specific error messages or behaviors during the flashing process may be necessary.
