Isaac SDK with Jetson Xavier NX

I’m trying to test one of the IsaacSDK gems on my Xavier NX. The getting started guide states that I should download JetPack 4.5.1.

For deployment of your robotics applications, Isaac works best with a Jetson Nano, Jetson Nano 2GB, Jetson Xavier, Jetson Xavier NX, or Jetson TX2 developer kit. Please make sure to install Jetpack 4.5.1 on your embedded devices. Isaac currently only supports this Jetpack version.

But it looks like the JETSON XAVIER NX SD Card Image comes with JetPack 4.6.

So, should I try using JetPack 4.6? Does IsaacSDK work fine with 4.6?

Or should I downgrade to JetPack 4.5.1? In which case, where can I find the right image I need to flash?

The right choice is to downgrade version 4.6 to JP4.5.1. I used the SDKManager to reflash the SD card in my Jetson. Here are some instructions to do that. Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation

It is the safest choice at least. Isaac SDK 2021.1 was qualified against Jetpack 4.5.1 before JP 4.6 was available.
