How to determine Jetson Orin Nano module type and SKU

Issue Overview

Users of the Jetson Orin Nano Developer Kit are seeking a method to determine the specific module type and SKU (Stock Keeping Unit) of their device, particularly when they are unsure about the memory capacity (e.g., 32GB vs 64GB). The issue arises when users need to identify their hardware configuration without relying on external documentation or physical inspection.

Possible Causes

1. Lack of familiarity with Jetson system commands: Users may not be aware of the specific commands to retrieve hardware information.
2. Confusion between part numbers (P/N) and SKU: Users might be incorrectly focusing on P/N when SKU is more relevant for identifying module specifications.
3. Limited documentation: The method to retrieve this information may not be prominently featured in user guides or quick start documentation.

Troubleshooting Steps, Solutions & Fixes

1. Use system commands to retrieve module information:

   a. To view the TNSPEC (Technical Name Specification) and other relevant information:

   cat /etc/nv_boot_control.conf
   

   This command will display details including the TNSPEC, which contains the module’s specific configuration code.

   b. To check the Device Tree Specification (DTS) file name, which includes the module’s part number:

   sudo dmesg | grep kernel-dts
   

   This command will show the DTS file name, which typically includes the module’s part number (e.g., p3701-0005).

2. Interpret the output:

   • The TNSPEC line from nv_boot_control.conf will contain a code like "3701-RC1-0005-A.0-1-1-jetson-agx-orin-devkit-", which indicates the specific module configuration.
   • The DTS file name from the dmesg output will include a part number like "tegra234-p3701-0005-p3737-0000.dts", where p3701-0005 is the module part number.

3. Use the SKU instead of P/N:
   As mentioned in the forum, it’s more effective to focus on the SKU rather than the P/N to determine the module specifications. The SKU can be derived from the information obtained in steps 1 and 2.

4. Consult official documentation:
   For a comprehensive list of SKUs and their corresponding specifications, refer to the official NVIDIA Jetson documentation. This will allow you to match the information obtained from your system to the exact module configuration.

5. If still uncertain:

   • Visit the NVIDIA Developer website and check the Jetson FAQ section for additional information on identifying your module.
   • Use the NVIDIA Developer forums to ask for assistance, providing the output from the commands mentioned above.

By following these steps, users should be able to accurately determine their Jetson Orin Nano module type and specifications without needing to remember or physically check the hardware details.
