Finding and Mapping Jetson OS and JetPack Versions on the Nvidia Jetson

/ Christopher Paquin

Updated – 2/24/2026

Below are all the methods that I have found to either find your Jetson OS version, or your Jetpack version (which includes Jetson OS version, Ubuntu version, CUDA Version, NVIDIA drivers, and firmware).

First let’s review the matrix and see how JetsonOS Maps to JetPack version (along with Ubuntu version, CUDA version, and release date)

Note:

  • Nano: supported through JetPack 4.6.x
  • Xavier: supported through JetPack 5.1.x
  • Orin: required for JetPack 6.x and newer

Commands to Find your Jetpack/Jetson OS Version

This is not an extensive list, but its what I have used in the past

jetsonInfo.py

Git clone the repo below.

https://github.com/jetsonhacks/jetsonUtilities

and then run jetsonInfo.py.

# ./jetsonInfo.py 
NVIDIA NVIDIA Jetson Orin NX Engineering Reference Developer Kit
 L4T 36.4.3 [ JetPack UNKNOWN ]
   Ubuntu 22.04.5 LTS
   Kernel Version: 5.15.148-tegra
 CUDA NOT_INSTALLED
   CUDA Architecture: 8.7
 OpenCV version: 4.5.4
   OpenCV Cuda: NO
 CUDNN: ii libcudnn9
 TensorRT: NOT_INSTALLED
 Vision Works: NOT_INSTALLED
 VPI: NOT_INSTALLED
 Vulcan: 1.3.204

L4T 36.4.3 is part of Jetpack 6.2, looks like the repo has not been updated since 2021 which is why Jetpack 6.2 is not recognized (also missing installed TensorRT). See section below for Jetson OS to Jetpack Version mapping

Per the git-repo

  1. The hardware designator is derived from the file: ‘/proc/cpuinfo’
  2. The L4T version is derived from the file: ‘/etc/nv_tegra_release’
  3. The Ubuntu version is derived from the file: ‘/etc/os-release’
  4. The Linux kernel version is derived from the file: ‘/proc/version’

Via /etc/nv_tegra_release

Below in bold you can see the Jetson OS release and revision.
