jffs2 on imx21ads board

[Nethra]

hi all, 

I m using imx21ads board, Bootloader is Redboot. 
linux is linux-2.6.22 version. Board with Jffs2 root filesystem as root is
not working. 
But Ramdisk booting is working...so i tried to mount jffs2 root file system
after 
booting board with ramdisk using mount command. It boots up with some error
message as given below. 

With df command it shows 100%...
