Checking Jetpack Version on Jetson Nano

Autonomous Machines Jetson & Embedded Systems Jetson Nano

Hi, I have bought a Jetson Nano recently.
I have flashed OS Image on a SD Card and then booted my Nano from SD card.

I also have Jetson TX2 and flashed jetpack many times using usual approach of downloading jetpack on a ubuntu host machine, run jetpack on host machine and flash TX2.

My problem is that :

  1. I want to know which jetpack version has been installed on my Nano?
  2. And why Argus libraries and samples are not present on my Nano ?

Hi shivkumar4680, you can check the L4T version (which corresponds to JetPack version) by running the following:

$ dpkg-query --show nvidia-l4t-core
nvidia-l4t-core 32.3.1-20191209225816

For example, L4T 32.3.1 corresponds to JetPack 4.3.

Have you checked under /usr/src/jetson_multimedia_api for the samples/headers? And the libraries should be at /usr/lib/aarch64-linux-gnu/tegra
