JFFS2 problem

hello...

ive already posted this on arm-general, so please dont flame on me.

i've got a PXA263 board running 2.4.21-rmk1-pxa1 from U-Boot 1.0.2. i
use a JFFS2 rootfs. ive tried an image from the web (for wepep250) --
and it works without problems.

but i can't get "selfmade" images to run.

here is what ive done:

on my development system:

i took the working image from the web:
"dd if=working_img_from_web.jffs2 of=/dev/mtdblock0"

then i mount this:
"mount -t jffs2 /dev/mtdblock0 /mnt/mtd"

and copied everything out
"cp -R /mnt/mtd/* /tmp/content"

then i tried to recreate a jffs2 image from this (unchanged!)
"mkfs.jffs2 -o /tmp/test.jffs2 -r /tmp/content -e 256 -p"

after this i flashed this image with u-boot exactly the same way as the
working image.

then when trying to boot i get the following:

[again and again...]


ive tried several different mkfs.jffs2 binaries (and also a self- build
from mtd-cvs) from the web without success. i think this tools
(respective my handling of this tool) is the problem cause the content
of the working and the nonworking image is the same???

it would be very nice if somebody advice me what im doing wrong...

thanks in advance Michael Palme.
