Hi everyone,

I have just installed jetpack 6.2 on SDK manager, but when I finish and use jtop. the jetpack version say: MISSING but the system runs normally. Is it good ?
Thank you for your help.

JetPack/SDK Manager is used to install Ubuntu plus the NVIDIA drivers (which is when it gets called “Linux for Tegra”, or L4T). The L4T release can be found via:
head -n 1 /etc/nv_tegra_release

What L4T release do you see? And what is your specific Jetson hardware?

If you go here and look up your L4T release, then you’ll see what hardware is compatible with it, and you’ll go to the web page specific to your release:
https://developer.nvidia.com/linux-tegra

You’re currently in the forum for the oldest Nano, which is really just a small form factor; the original Nano is a TX1, and there are also Nanos up to and including Orin. JetPack 6.x (which normally installs L4T R36.x) is not compatible with the original Nano. In order to talk about what software is there or not one normally has to know which Nano it is, e.g., maybe it is Xavier or Orin. It is also necessary to know if this is the developer’s kit sold by NVIDIA, or if it is some third party carrier board with a commercial module on it (which tends to use different firmware, and thus different flash software).

Also, JetPack/SDKM tends to be used with a specific L4T release, although it has options to flash older L4T releases if the right option is used. One can go to this URL on JetPack/SDKM releases, and this will tend to go to the same URL as the L4T release goes to:
https://developer.nvidia.com/embedded/jetpack-archive

Incidentally, Jetson Nanos (of all generations, including up to Orin) have only an SD card slot which is on the module itself; third party carrier boards might have an SD card slot, but it would be on the carrier board, not the module. The modules without an SD card slot have eMMC memory and are commercial modules, while the modules with their own SD card slot come with developer kits and do not have eMMC.

Hi sir,

thank you for your reply.

I use jetson orin nano developer kit with SSD. I’ve check the first link and I see that I’ve installed the right version for my Orin. In the jtop board, it shows me the cuda version, cudnn and tensorRT but jetpack.

Are you starting jtop on command line? If so, what do you see from “which jtop”. Also, what do you see from:
dpkg -l | grep -i jtop

What do you see from “head -n 1 /etc/nv_tegra_release”?
