Nanopi-neo fails to boot with isar-image-base-debian-bookworm-nanopi-neo.wic

[baprusty]

Steps:

• Clone the master branch and created isar-base-image for nano pi neo
• Flashed the created image to SD-card
• Attached the sd card to nanopi (Note: nanopi-neo used here doesn't support internal emmc) and powered on
• Powered the nanopi

Booting stops at:

Begin: Running /scripts/local-block ... mdadm: No arrays found in config file or automatically
done.
Begin: Running /scripts/local-block ... mdadm: No arrays found in config file or automatically
done.

done.
Gave up waiting for root file system device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/mmcblk2p1 does not exist.  Dropping to a shell!

Root cause seems like: fee0c41

• I tried building the image by reverting commit
• Tried building and booting: It is able to boot the image and login prompt appears

Checked info from official page: https://wiki.friendlyelec.com/wiki/index.php/NanoPi_NEO3#Running_the_build

• Looks like mmcblk0 is for external SD card and mmcblk2 for internal emmc

Hi @baprusty , thanks for reporting! It either might be, that the inconsistency of the device names in the firmware provided device tree has been fixed, or the names are simply not stable (despite what the documentation states).

As proposed in the commit message, we probably should just rely on partition UUIDs. This also makes it possible to copy the image to the eMMC without any further changes.

Could you please try to replace --ondisk mmcblk2 with --use-uuid in the WKS file and try again?

Hi @fmoessbauer, Thanks, With the --use-uuid change:
