Mounting rootfs


Hi,

I don't know if this is the right place to post this querry,

I  have a specific doubt about  mounting rootfs at boot up of linux-sh.

I link my linux-sh kernel at address 0x8c100000,
Download the same to my RAM,
give a jump using Redboot to 0x8c200000,
The kernel boots up !!! but without any rootfs..

To add rootfs, I created an ext2 file in my Host machine, and downloaded the
same(binary) to RAM location at 0x8ca00000.

Using the kernel comand line parameters, I have specified the INITRD Address
as 0x8ca00000.and also the size,...and the root=/dev/ram0,,..

Still the kernel is not able to mount the rootfilesystem

please advice where I went wrong...

Note:
I work with MS7729SE01 board.
Bootloader I use is Redboot.
I don't intend to use PCMCIA on board.

Rupesh
