MTD nand driver help

[Tushar Kapse]

Thank you for your nice support..
here i will explain detail of my problem.
1.I have PXA255 SBC board, and ported linux 2.6.12 on it without File System.
     Linux Image : Resides in NOR Device ( 4Mb)
     File System:  To be reside in NAND Device (128Mb). Still to be done .
2.Now i want to put JFFS2 file system on NAND device.
3. First I have created the Linux image with MTD support (also JFFS2
file system selected) and ported on NOR device. On power ON of SBC
board, Linux is booted and got error "Kernel panic - not syncing: VFS:
Unable to mount root fs on unknown-block(31,0)"
4. As there is no JFFS2 File System on it we got this error.
5. We have downloaded the MTD utilities on the host system (PC).
Kindly please tell me the procedure to put JFFS2 FS in the NAND device
for the first time.
Note that we don't have any filesystem on NAND device.

Regards,
Tushar
