created  jffs2 image using mkfs.jffs2 on host
----------------------------------------------------
mkfs.jffs2 -r /mnt/tmp -e 0x10000 -o image.jffs2 -b


on evaluation (PQ2FADS-ZU) board....
--------------------------------------------
setenv ipaddr 192.168.178.234
setenv serverip 192.168.178.110
setenv ethaddr 00:99:23:44:ad:de
setenv bootcmd 'tftpboot 0x1000000 jffsenabled\;bootm 0x1000000\;'
setenv bootargs root=/dev/mtdblock0 rootfstype=jffs2
ip=192.168.174.231:192.168.178.110:192.168.174.47:255.255.255.0:cashel:eth1:off 


steps fallowed are....

erase  FF800000 FFDFFFFF
tftpboot 0x100000 image.jffs2 
cp.b 100000 FF800000 4dc874
run bootcmd

linux does not bootup...

what is the problem ? 

I m also trying to mount jffs2 after nfs mounting.....
-------------------------------------------------------------

cat /proc/mtd and cat /proc/partitions are working fine.

steps fallowed are...

1. mkfs.jffs2 −−pad=3145728 −−eraseblock=262144 −−root=/mnt −−output
image.jffs2
2. flash_erase /dev/mtd0
3. cp /var/tm/image.jffs2 /dev/mtd0
4. mount  -t jffs2 /dev/mtdblock0 /mnt

it is not working?

thanks in advance.

best wishes,
Nethra
