I have recently managed to get SPI boot to USB SSD working on my Odroid N2+.

 

However, to get there, I had to manually set

setenv rootdev "/dev/sda1"

in my /boot/boot.cmd

 

With that set, SPI boot works. However, obviously I should not set it manually there, and the setting gets overwritten by armbian-config.

 

 

My understanding is, that I should let boot.cmd unchanged (rootdev "/dev/mmcblk0p1") and armbianEnv.txt should do its magic, but the rootdev setting in armbianEnv.txt is simply ignored upon SPI boot and it fails to boot, as it tries to load the root fs from SD card...

 

Any pointers, what might go wrong here or how to persist the boot.cmd change?

Don't forget to recompile. Written at the end of boot.cmd

-> recompile with:
# mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

for me it works with that both fixes.
(15sec petitboot and /dev/sda1 argument change)

Hmm, I did recompile to make the change effective.

 

While playing with it, /boot/boot.cmd got reset to default values at some point. I supected the armbian-config script (probably while enabling some device tree overlay). I could not reproduce it later on, but was a bit afraid of this happening at some point in time in "productive" use.

 

Decided for me to go with booting via SD card until I find a better solution...

Hmm, they mostly suggest not to use armbian, which would be a pity, though
