How to read EEPROM data from NVIDIA Jetson Platforms

Keywords: Orin Nano, Orin NX, 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.

NVIDIA Jetson SoM models and part number

Use this table to cross-reference the module part number obtained from the EEPROM dump.

What is EEPROM?

EEPROM stand for electrically erasable programmable read-only memory. Is a non-volatile memory chip used to store important information, such as the module's part number, used for identifying and validating the System-on-Module (SoM).

Reading the EEPROM information

In this tutorial I will be using an Orin NX 16GB SoM part number p3767-0000.

1. Identify the I2C bus where the EEPROM device is. It should be located at address 0x50 of the bus for the SoM. For example for I2C bus 0:

 
sudo i2cdetect -y -r 0

Returns:

 
nvidia@tegra-ubuntu:~$ sudo i2cdetect -y -r 0
     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: -- -- -- -- -- -- -- --

At address 0x50, the UU references the EEPROM.

2. Read EEPROM contents:

 
sudo i2cdump -f -y 0 0x50

Returns:

 
nico@tegra-ubuntu:~$ 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
