Hello,
I'm new here - and please forgive me when I ask some newbie questions.
I also own such a NAS system (MEDION P89634 MD 86783, 2x2 TB NAS) as some of the users here have written of (helge and saschbear).
Before I start with installing a new uboot and or kernel etc., I'd like to completely backup the EEPROM (the environment is saved there, I suppose) and the flash (uboot, kernel, initrd).
Is there a safe and verified way to do so?
I think it was helge; I stumbled about some scripts dd'ing the mtd-devices (called raw backup) and another variant using nanddump (called nandbackup).
Is that the proven way to do a backup?
And when I have a backup: how can it be restored?
As I read in the other threads: after booting the kernel: it just stops without any further messages.
Just an idea: if it is the wrong/missing DTB: can it be taken from the existing initrd from the manufacturer?
Thanks in advance,
Peter2017
