Is there a way I can install JetPack 4.6.2 on my AGX Xavier using Ubuntu 20.04?
I don’t want to go through the whole process of installing Ubuntu 18.04 just for that one thing.
Also, how stable / unstable is the JetPack 5,0 Developer Preview?
4.6.2 is with Ubuntu 18.04. For 20.04, please use Jetpack 5. You can try developer preview first and wait for next production release.
Sounds more like the host PC being 18.04 versus 20.04 which you are interested in. It is the GUI front end, JetPack/SDK Manager, which has this requirement. I think command line flash will work with 4.6.2 on a wider range of hosts versus GUI.
If everything has been unpacked and set up correctly (which is something SDKM would do for you), then flashing might be as simple as something like this (from the
sudo ./flash.sh jetson-xavier mmcblk0p1
(there can be some minor variations in the target name)
This would not give you options to install extras like CUDA. You would then have to do this yourself as an extra step.
In the past this is how I developed from Fedora.
