Hm, that's weird. Can you try with the old driver (pxa3xx)?    

Ah you're right, my NAND was damaged ...

Alternatively, you can type 'nand bad' from uboot to check if it
detects the same bad blocks.    

Mmmh no, the SPL is barebox in my case. Do you have a command in
linux or barebox to do the same thing ?  

Not sure, but nand -i should do the trick.

But I am not sure this is still relevant now we know the NAND was
damaged by the previous experiments (sorry about that). Can you put the
NAND in a clean state and report us if it is still failing?

In order to do that you'll have to scrub the blocks storing the BBT, and
I'm not sure barebox supports that. Linux does not, for sure, so if you
want to forcibly erase bad blocks from linux, you'll have to comment
these lines [1].
