Flash in unsecure factory floor problem

Issue Overview

Users are experiencing difficulties when attempting to flash the QSPI memory of the Nvidia Jetson Orin Nano Dev board in an unsecure factory environment. The specific issue occurs when using the massflash package generated for factory flashing. When executing the flashing command, users encounter a timeout error in USB communication, preventing successful flashing of the device.

Possible Causes

1. Incorrect memory configuration: The massflash package may be using the wrong memory configuration for the Orin Nano 8GB model.

2. USB communication issues: The timeout error suggests problems with the USB connection between the host computer and the Jetson device.

3. Improper device state: The Jetson device may not be in the correct recovery mode when attempting to flash.

4. Incompatible flashing method: The chosen flashing method may not be suitable for the specific requirements of flashing only the QSPI memory.

Troubleshooting Steps, Solutions & Fixes

1. Verify device recovery mode:
   Ensure the Jetson Orin Nano is properly set to recovery mode before initiating the flashing process.

2. Generate the massflash package:
   Navigate to the Linux_for_Tegra directory and run the following command to create the massflash package:

   sudo ./tools/kernel_flash/l4t_initrd_flash.sh -p "--no-systemimg -c bootloader/t186ref/cfg/flash_t234_qspi.xml" --network usb0 --massflash 1 --no-flash jetson-orin-nano-devkit nvme0n1p1
   

   This will generate the "mfi_jetson-orin-nano-devkit.tar.gz" file.

3. Prepare the factory computer:
   Extract the "mfi_jetson-orin-nano-devkit.tar.gz" file on the factory computer where flashing will be performed.

4. Flash the device:
   In the extracted directory, run the following command to flash the Jetson Orin Nano:

   sudo ./tools/kernel_flash/l4t_initrd_flash.sh --massflash 1 --network usb0 --flash-only
   

   This command should properly flash the QSPI memory.

5. Monitor serial console:
   If issues persist, connect a serial console to the Jetson device to monitor the boot process and identify any specific errors or hang-ups during flashing.

6. Check USB connection:
   Ensure a stable USB connection between the host computer and the Jetson device. Try using a different USB cable or port if issues continue.

7. Verify massflash package integrity:
   Double-check that the massflash package was generated correctly and includes all necessary files for flashing the QSPI memory.

8. Consider alternative flashing method:
   If problems persist with the massflash approach, consider using the standard flashing method directly from the Linux_for_Tegra directory:

   sudo ./flash.sh --no-systemimg -c bootloader/t186ref/cfg/flash_t234_qspi.xml jetson-orin-nano-devkit internal
   

   This method may be more reliable for flashing only the QSPI memory.

9. Update Jetpack and flashing tools:
   Ensure you are using the latest version of Jetpack and the flashing tools to avoid any known issues or incompatibilities[1].

10. Seek support:
    If none of the above steps resolve the issue, consider reaching out to Nvidia developer support or community forums for further assistance with your specific setup and requirements[1].
