Mounting JFFS2 compressed Ramdisk on MTD partition

[Niraj Maheshwari <niraj.maheshwari@gmail.com>]

Hi.

I am using JFFS2 and MTD on our target for booting
the Ramdisk from MTD device ( Intel W18 Flash ) 

Kernel command line: root=/dev/mtdblock1 rw mem=64M 
rootfstype=jffs2 console=ttyS0,115200 ramdisk=8192

I have compressed the RAMDISK to have JFFS2 Ramdisk image and
loaded in to the Flash on the specified memory location. I have also
created a MTD partition ( /dev/mtdblock1) which is pointing to flash
memory location where the JFFS2 compressed ramdisk image is there.

My idea is to load JFFS2 RAMdisk from flash ( specified in the KERNEL
config line ) because i have a very limited memory in Flash.

Here is the logs for the same. I am getting this
error eveytime when Linux Kernel tries to mount the JFFS2
compressed Ramdisk from the Flash Device.

logs:

 INIT: Eep. Unknown node type 0080 at 00186f34 was
 marked REF_UNCHECKED
 Node header CRC failed at 00186f34. But it must have
 been OK earlier.
 Node was: { 0080, 2080, 00800080, 00800080 }
 Node totlen on flash (0x00800080) != totlen from node
 ref (0x000001b4)

and it keeps on repearing the same way.

I am formatting the flash completely. I have verified that all
the flash sectors have been erased correctly. By the way i am using
NOR Flash ( Intel W18 Flash).

Important thing to note that :

I am able to load the RAMdisk in /mnt/temp directory by issuing :

mount -t jffs2 /dev/mtdblock1 /mnt/temp.

But if i ask kernel to pick up the RAMdisk from /dev/mtdblock1 in the
kernel config line then it gives me lot of errors as mentioned above.

Do you have any idea ?

Thanks and regards
