How to Check BOARDREV for Jetson Orin Nano Multi-Flashing

Issue Overview

Users are experiencing difficulty in determining the correct BOARDREV value when performing multi-flashing on the Nvidia Jetson Orin Nano Developer Kit. This information is crucial for properly configuring the flashing process using the l4t_initrd_flash.sh script. The issue arises during the setup phase, specifically when preparing the command for flashing multiple devices simultaneously.

Possible Causes

1. Lack of Documentation: Users may not be aware of where to find the necessary board information for the Jetson Orin Nano.

2. Confusion with Board Models: There might be confusion between different Jetson board models, leading to the use of incorrect configuration files or flashing commands.

3. Misinterpretation of Configuration Files: Users may have difficulty interpreting the information in configuration files like /etc/nv_boot_control.conf to extract the required BOARDREV value.

Troubleshooting Steps, Solutions & Fixes

1. Identify Board Information Pattern:
   The board information follows a specific pattern:

   <BOARDID>-<FAB>-<BOARDSKU>-<BOARDREV>
   

   This pattern can be used to extract the necessary values for flashing.

2. Extract Board Information:
   For the Jetson Orin Nano, based on the provided configuration:

   • BOARDID = 3767
   • FAB = 300
   • BOARDSKU = 0003
   • BOARDREV = M.2

3. Correct Flashing Command:
   Use the extracted information to construct the correct flashing command:

   sudo BOARDID=3767 FAB=300 BOARDSKU=0003 BOARDREV=M.2 ./tools/kernel_flash/l4t_initrd_flash.sh --no-flash --network usb0 --massflash 5 jetson-orin-nano-devkit-emmc mmcblk0p1
   

   Make sure to replace jetson-xavier-nx-devkit-emmc with jetson-orin-nano-devkit-emmc as it’s specific to the Orin Nano.

4. Verify Board Configuration:
   Double-check the board configuration by examining the /etc/nv_boot_control.conf file:

   cat /etc/nv_boot_control.conf
   

   Look for the TNSPEC line, which should contain the board information in the correct format.

5. Use Correct Board Configuration:
   Ensure you are using the correct board configuration for the Jetson Orin Nano. Avoid using configurations meant for other models like the Xavier NX.

6. Consult Official Documentation:
   Refer to the official Nvidia Jetson documentation for the most up-to-date and accurate information on flashing procedures and board configurations for the Orin Nano.

7. Seek Community Support:
   If issues persist, consider seeking help from the Nvidia Developer Forums or other community resources dedicated to Jetson development.

By following these steps and using the correct board information, users should be able to successfully perform multi-flashing on their Jetson Orin Nano Developer Kit.
