Flashing Image to the SD Card is Failing

Issue Overview

Users are experiencing failures when attempting to flash images to the SD card for the Nvidia Jetson Orin Nano Developer Kit. The specific symptoms include error messages during the flashing process, such as "Error: Return value 4" and "Error: Invalid argument during seek for read on /dev/mmcblk1," indicating issues with the storage device or the flashing method used. This problem occurs both during initial setup and when trying to utilize different flashing methods as outlined in the developer guide. Users have reported that a 32GB SD card is insufficient for the flashing process, as indicated by one user needing to switch to a 64GB card for successful operation. The impact of this issue is significant, as it prevents users from utilizing their devices effectively, leading to frustration and delays in development.

Possible Causes

• Hardware Incompatibilities: Using an SD card smaller than 64GB may lead to failure during flashing, as the developer guide does not specify this requirement.
• Software Bugs or Conflicts: The flashing scripts may contain bugs or not be fully compatible with certain configurations of the Jetson Orin Nano.
• Configuration Errors: Incorrect parameters or commands in the flash scripts can result in failures.
• Driver Issues: Missing or outdated drivers related to USB or SD card interfaces may hinder the flashing process.
• Environmental Factors: Power supply issues or unstable connections (e.g., USB cables) can affect the flashing process.
• User Errors: Misconfiguration in command usage or incorrect device identification can lead to unsuccessful attempts.

Troubleshooting Steps, Solutions & Fixes

1. Check SD Card Size:

   • Ensure you are using a 64GB or larger SD card. The use of a 32GB card has been reported as problematic and not supported.

2. Use Correct Flashing Commands:

   • For initial flashing, use:

     sudo ./flash.sh jetson-orin-nano-devkit internal
     

   • If using an external device:

     sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device mmcblk1p1 -c tools/kernel_flash/flash_l4t_external.xml -p "-c bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 jetson-orin-nano-devkit internal
     

3. Verify USB Connections:

   • Ensure that your USB cable and ports are functioning properly. A faulty connection may prevent the device from being recognized.

4. Monitor Logs for Errors:

   • Use --showlogs in your flash command to capture detailed logs that can help diagnose issues.

5. Re-flash with Updated Software:

   • Consider re-flashing using the latest version of JetPack that is compatible with your device (e.g., JetPack 5.x). Ensure all dependencies are met before proceeding.

6. Check Device Status:

   • Ensure that the Jetson Orin Nano is in recovery mode before attempting to flash. You can enter recovery mode by connecting specific pins on the board.

7. Inspect XML Configuration Files:

   • Validate that your XML configuration files are correct and compatible with your device specifications.

8. Seek Community Support:

   • If problems persist, consult forums or community discussions for similar issues and potential fixes shared by other users.

9. Best Practices for Future Prevention:

   • Always verify hardware compatibility before starting any flashing procedure.
   • Keep your software and drivers updated to avoid conflicts.
   • Regularly check Nvidia’s developer forums for updates on known issues and patches.

10. Document Any Unresolved Issues:

    • Note any persistent errors or behaviors that do not align with expected outcomes for further investigation within community support channels.

By following these troubleshooting steps, users should be able to diagnose and resolve issues related to flashing images onto their Jetson Orin Nano Developer Kits effectively.
