Keywords: NVIDIA Jetson, validation, verification,system-on-module, EEPROM

Description

This page explains how to validate and verify your NVIDIA Jetson System-on-Module (SoM) by identifying its hardware part number and related information. It includes steps for reading module data over I²C, interpreting the results, and using additional system commands to confirm the exact Jetson module installed on your carrier board.

Identifying your Jetson SoM

The most reliable and authoritative approach is reading the module’s EEPROM over I²C, which contains the official part number and hardware information programmed by NVIDIA. Additional commands are included to cross-check the module type using the device tree, system interfaces, and other board-level data. For this wiki, an NVIDIA Jetson OrinNX 16GB is used as reference.

Reading the EEPROM

The EEPROM address on NVIDIA Jetson Platforms is usually on I²C bus 0 address 0x50. Follow below steps to read the EEPROM from your SoM:

1. Detect EEPROM:

 
sudo i2cdetect -y -r 0

You should see a UU on address 0x50 which represent the EEPROM.

 
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:                         -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: UU -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- 67 -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --

2. Dump EEPROM content:

 
sudo i2cdump -f -y 0 0x50

Take for example the output for a Jetson OrinNX 16GB module:

 
sudo i2cdump -f -y 0 0x50 
No size specified (using byte-data access)
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f    0123456789abcdef

3. From this output we can see the module part number here:

 
699-13767-0000-301

From the table on section NVIDIA Jetson SoM models and part number, it is confirmed the NVIDIA Jetson module is an OrinNX 16GB.

Additional Commands for Module Verification

These commands provide supplementary ways to check your Jetson SoM and board information. Unlike reading the EEPROM, these methods are not authoritative and can be modified by software. Use these commands only for cross-checking or convenience.

1. Run the following command to check your board’s model:

cat /sys/firmware/devicetree/base/model

Should return something like:

nvidia,p3768-0000+p3767-0000nvidia,p3767-0000nvidia,tegra234

2. Check the SoM with:

cat /proc/device-tree/compatible
