JetPack version


In order to read JetPack version I ran:
cat /etc/nv_tegra_release

and got:
# R32 (release), REVISION: 3.1 …

But according to JetPack archive, there is no such version: R32. Only 32.1
Does it make sense ?

Thank you,

No, what you are talking about does not make sense. 32.3.1 indeed a valid version.

32.1 is even older that 32.3.1…

And actually 32.x is “L4T version” not really the jetpack version

A list of L4T releases (which a given JP release is tied to):

A list of JetPack/SDK Manager releases:

Note that for the more recent releases one can use the most recent JetPack/SDKM and start it with this to see older releases:
sdkmanager --archivedversions

However, if the release is old enough, then the “--archivedversions” does not work.


I still do not understand:
How can I know what is the JetPack version currently burned on my Xavier ?
The output of /proc/version is: Linux version 4.9.140-tegra … Mon Dec 16 13:32:15 PST 2019

Thank you,

You can look up the version of JetPack that corresponds with the version of L4T you are running (from cat /etc/nv_tegra_release) by searching for the L4T version. For example, googling “L4T R32.3.1” shows that it is JetPack 4.3.
