Install Linux onto AGX Xavier using SDK Manager from Ubuntu 20.04?

TARGET OPERATING SYSTEM: Linux, No available releases for Ubuntu 20.04

  • It looks I’ve got to flash AGX Xavier under Ubuntu 18.04 ??? Is there a way to flash AGX Xavier using SDKManager under Ubuntu 20.04?
  • Otherwise, is there a way to flash AGX Xavier using SD card via command line, instead of using SDKManager?

Can anybody give me a hand please?

Cheers
Pei

The whole SDKM/JetPack may not run correctly with Ubuntu 20, but you would be able to flash a Jetson from command line with many other Linux distributions.
