unable to open an initial console


Hi,
I am using atmel 9260 and am trying to mount a jffs2 filesystem.
I enabled the mtd feature of the kernel in a way that it creates a
bootloader and filesystem partition in mtd0 and mtd1. I have loaded the
jffs2 image and copied it to a random address in the dataflash 0x40400000.
When the kernel booted up.. it went on until it displayed :

************************************************************************
Warning: unable to open an initial console.
Kernel panic - not syncing: No init found. Try passing init=option to kernel.

************************************************************************
I looked at my filesystem and it contained /dev/console. I do not know what
the problem is.
Please help me.

Thanks,
Ranjith

P.S. Here is the console display:

Does the init script exist?
Do you have initrd image?
