Thank you all for this series of notes. I have been operating Armbian 22.08 successfully using the sd card on my PBP and like it BUT I would like to boot from emm. I have tried dozens of ways to install it to no avail. Seems to be associated with the rootdev=UUID=...
If I use the UUID provided in the Armbian-install then I can boot from emm but it ends up mounting and running from the SD partition.
Is there any code that can be inserted into the /boot/armbianEnv.txt file that would provide better diagnostics? To me it appears as if the emm partitions UUID is not available at boot time.
Thanks,
Carl
