Update 1:
So I found that I can install balenaEtcher on Nvidia Jetson Nano by building the ARM version myself - I following instructions: https://github.com/futurejones/balena-etcher-arm
After downloading Jetpack 6.1 cdcard image - I flashed it to my system NVMe drive, resized APP partition to full size, powered down Jetson Nano - removed SD card - and booted - but seems boot loader is still expecting to find image at /dev/mmcblk0p1 (sdcard) instead of NVMe disk /dev/nvme0n1p1 - will investigate further later :-)
Update 2:
And finally I found that I can mount /dev/nvme0n1p1 to e.g. /mnt/nvme0n1p1.
Then as super user I can modify /mnt/nvme0n1p1/boot/extlinux/extlinux.conf, and change:
root=/dev/mmcblk0p1
root=/dev/nvme0n1p1
And then it boot from NVMe without sdcard or any need to using SDK Manager to flash it.
If you have a M.2 to USB adaoter, this should make it possible to flash the NVMe SSD on any linux system:
- Insert NVMe M.2 SSD into an M.2 to USB adapter.
- Use balenaEtcher to flash Jetpack sdcard image to NVM’e.
- Mount partition “nvme0n1p1” (use Disk manager to identify it name on your linux system)
- On the mounted partition, modify /boot/extlinux/extlinux.conf, so that root=/dev/mmcblk0p1 is placed with root=/dev/nvme0n1p1
Insert M.2 SSD into Nvidia Jetson Nano, boot and follow guide with display / keyboard attached.
(I will test this scenario tomorrow when my M.2 to USB arrives).
