[Ltib] Problem mounting JFFS2 file system while loading linux kernel from LTIB on imx27 ADS board

[rmarathe]

Team,

I use the imx27 ADS board and a Linux Redhat EL ver 5 Server based host
machine. I took latest from LTIB and compiled a kernel. I just want to run
s simple gstreamer based application and play a video on ADS. My kernel
size is less than 2 MB while the size of file system is around 42 MB. I
get an error like,

------------------------------------------------------------------------------
input: mxc_ts as /class/input/input1



mxc input touchscreen loaded

Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(31,2)
----------------------------------------------------------------------------

I see a kernel panic. The commands I used to load kernel and root fs are
as under:
==========================================================================
REDBOOT>load -r -b 0x100000 zImage

REDBOOT> fis create kernel

To load rootfs.jffs2 file

REDBOOT >load -r -b 0x100000 rootfs.jffs2

REDBOOT >fis create root -l 0x6D00000

loading is done







REDBOOT >fis load kernel

REDBOOT>exec -b 0x100000 -l 0x200000 -c "noinitrd console=ttymxc0,115200
root=/dev/mtdblock2 rootfstype=jffs2 rw init=linuxrc ip=none
mtdparts=none"




==========================================================================


Can any body please let me know what is wrong with the above config?
