I have an OpenHab 3.1 installation on a raspberry 4 running. I'm currently using raspiBackup to create a full backup of the system and also having an .img file to restore it when needed via Etcher under Windows.
Now I wanted to give the restore a try and boot it from a raspberry 3b. But all I get is a black screen. I checked the /boot
directory and it seems bootcode.bin
and start.elf
are missing on the origin system. Adding them manually from here to the restored boot partition shows still a black screen, but at least the green ACT led is blinking 4 times - which basically means it has issues loading the start.elf
- as far as I understood it.
My actual question is now, is it even possible to run a RasbianOS installed on a rpi4 on a rpi3b? I'm booting from a SSD directly connected via the same SATA2USB adapter - in both cases. If I do a fresh RasbianOS install using the rpi3b, it boots properly.
