large-nand flash mount ?

[최영일]

Hi
I am developing system with cpu au1550 and 2G nand flash?
I want root filesystem by 2G nand flash. 
for test, I can mount nand flash and read, write to flash.
so, I make jffs2 filesystem and write to flash.
then, I make to boot with boot argument(root=/dev/mtdblock0), but fail
the message follows
----------------------------
mtdblock_open
ok
mtdblock: read on "Db1550 NAND FS 0" at 0x400, size 0x200
nand_read_ecc: from = 0x00000400, len = 512
mtdblock: read on "Db1550 NAND FS 0" at 0x600, size 0x200
nand_read_ecc: from = 0x00000600, len = 512
mtdblock_release
nand_sync: called
ok
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,0)
-----------------------------------
did anyone success to root mount with 2G large nand flash(jffs2)?
