JFFS2 error: on mounting

Fri Feb 6 04:17:08 EST 2009

Hi all,

I am a newbie to JFFS2 flash file system. On my Intel IXP425 wireless board,
I am have severe issue with JFFS2. The onboard 8MB flash has
the following partitions and flashed with OpenWRT linux kernels and  jffs2
rootfs and Config data images.

root at OpenWRT:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00060000 00020000 "RedBoot"
mtd1: 00140000 00020000 "kernel1"
mtd2: 00500000 00020000 "rootfs1"
mtd3: 00140000 00020000 "kernel2"
mtd4: 00500000 00020000 "rootfs2"
mtd5: 00100000 00020000 "Config"
mtd6: 00020000 00020000 "RedBoot config"
mtd7: 00020000 00020000 "FIS directory"

root at OpenWRT:~# mount
rootfs on / type rootfs (rw)
/dev/root on / type jffs2 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev)
tmpfs on /dev type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=600)
/dev/mtdblock5 on /mnt/rw type jffs2 (rw)
When the board is up and running for the first time, on updating the Config
(mtd5) parition  from GUI web, and on next reboot the system gets
failed to mount the Config jffs2 (mtd5) partition and throws the following
error
