JFFS2 MOunt problem

[Vikram Mehta]

Hi folks,
I have built a kernel in RAM and Put in Jffs2 Support with two partitions.

On Booting However I get these messages for a huge number of times
..........
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x000e20c8:
0x0007 id
...........
JFFS2: Erase block at 0x000c0000 is not formatted. It will be erased
.....
...........

when running the command
 mount -t jffs2 /dev/mtdblock1 /mnt

I get

mount: Mounting /dev/mtdblock1 on /mnt failed: No such device

What could be the reason?
