Jetpack version check


I typed the following command to check the Jetpack version.
$ sudo apt show nvidia-jetpack -a

Two versions of Jetpack are output. (4.6.2-b5 and 4.6.1-b110)
Which Jetpack is my Jetson using now?

hello Heartful-echo,

please refer to JetPack Archive | NVIDIA Developer,
you may mapping the $ cat /etc/nv_tegra_release with JetPack version,
so, # R32 (release), REVISION: 7.2, it is JetPack 4.6.2.

Hi, JerryChang

Thank you.

I know how to read the version of L4T that supports JetPack.
What I want to know is that I looked up the JetPack version of Jetson AGX. Why are the two versions output?

I remember flashing JetPack 4.6.1 using the JetPack SDK Manager.
Because I was initially using JetPack 4.6.2, but I flashed to JetPack 4.6.1.

hello Heartful-echo,

those packages were fetch from… /etc/apt/sources.list
it checks via APT’s package cache (through ethernet) instead your locally installed package.

Hi JerryChang

Thank you.
I understand!
I will now use “cat / etc / nv_tegra_release” to find out the Jetpack version.
