how to mount nand as data nand

[yeyue]

I use  mpc8313erdb to control nand as data nand and hope to use is as harddisk.

and do as follows I can't get what I want.

can anyone give some help to resolve this.

thank you!

nand flash is K9F5608U0D,

I  put the uboot,rootfs(ext2.gz.uboot),kernel ,dtb on the nor flash,

first I write a file to the nand by mtd_debug tool,and can read it back correctly

~ # ./mtd_debug write /dev/mtdblock5 0x40000 502388 aa.txt

~ # ./mtd_debug read /dev/mtdblock5 0x4000 0x09 bb

after I reboot the system it still works well,

but after I poweroff and repower on it goes wrong.

~ # ./mtd_debug read /dev/mtdblock5 0x40000 0x09 bb

end_request: I/O error, dev mtdblock5, sector 0

Buffer I/O error on device mtdblock5, logical block 0

end_request: I/O error, dev mtdblock5, sector 0
