  1. It seems that Jetson Xavier NX cannot boot from NVMe:

    Reading in Developer Guide:
    Flashing to a NVMe Drive
    Applies to: Jetson Nano, Jetson TX2 series, and Jetson TX1 devices only

        1. I’d be eternally grateful if someone can figure out the steps to take for the Jetson Xavier NX to get booting from NVME to work and write an easy to follow guide on how to do this.

          The current set of instructions that are being pointed to are way too complex for this simple soul to figure out.

    1. I’ve asked for a simple guide on how to achieve boot from NVMe on the Jetson Xavier NX and onbe of the developers from NVIDIA responded that this isn’t supported yet on the NX. They are working on making this work on the next JetPack release. The reason for this was that the NX uses a different bootmanager (CBoot i.s.o UBoot) and they need to write the correct modifications for that one.

  2. 1) I have been using the JetsonHacks article on booting from the nvme SSD on my NX using rootOnNVME. It works well except when we have these major updates. I then go back and boot from the the SD card by removing the /etc/setssdroot.conf and reboot to the SD card.

    2) Update of Jetson NX involves what is discussed in the following link as to go to JetPack4.5:

    3) I then go back to step 1 and appears to be good to go to be running everything off of my SSD again.

    Is there a better way to approach this?
