After strange issues of my running system out of nothíng

(

)

I decided to flash a new sd card and try to restore a backup to it after 1st boot (as I don’t have a second mmc at hand).

I got warnings that uuid doesn’t match and that I have to modify them in boot and fstab.

On the other side i read in an issue, that the script should change this after restore.

In my case the system won’t boot (reboot after restore). I actually lits steady green-blue and that’s it.

Can someone clarify the steps I have to make it running again? Are there further steps to do when moving from mmc to sd (as a fresh sd ?card is booting I should work without)?

I’ve just seen that the mmc device has 2 partitions (boot and /) but the freshly installed sd card has only one (and boot is a subdirectory of /).

Is this the reason for the boot problem? How can I modify the configuration for a working (restored) system?

I did an image backup with usbit and wrote it to an sdcard.

Everything is ok afterwards, so the cause seems to be a damaged emmc…
