OK Yves.
I did all of this but still having the same problems.
I just have one question now. Is it normal that I have mtd devices
mapped to <NULL> ?
(see the trace below)
and can you tell me some about the "wrong magic" trace below ??

You might want to double check that the mtd partition you use
as a root is at the proper address (or alternatively, that you
wrote the JFFS image at the beginning of /dev/mtd2).
(Mentionning that because the first dump:

looks very much like the beginning of a Linux kernel, which
shouldn't be there)

Maybe you can do that with JFlash. Otherwise, if you have an
otherwise running system (with a ramdisk for example), you'll
find two utilities in the MTD package called erase and eraseall
that do just that.
eraseall /dev/mtd2
will erase the complete corresponding partition
HTH,
