Hi all,

I am working on an Assabet like board(SA1110).
but when I enable mtd device(M-systems Millenium)I am
able to see the driver recognizing the Millenium chip.

After booting I have added following links 

mknod /dev/nftla b 93 0
mknod /dev/nftla1 b 93 1
mknod /dev/nftla2 b 93 2
mknod /dev/nftla3 b 93 3

and 

mknod /dev/mtd0 c 90 0
mknod /dev/mtd1 c 90 1
mknod /dev/mtd2 c 90 2
mknod /dev/mtd3 c 90 3

and in bootup I am getting some errors like
out-of-line wait
_DoC_WaitReady called for out-of-line wait
.
.

_DoC_WaitReady called for out-of-line wait
Could not find valid boot record
Could not mount NFTL device

and using nftl_format I tried to format the diskon
chip But I get an error like the following

NFTL_open
ENODEV: thisNFTL = 0, minor = 23808, ip = c94ac4c0, fp
= c965caa0
NFTL_open
ENODEV: thisNFTL = 0, minor = 23809, ip = c94ac6e0, fp
= c965ca20

The only thing I could do was 

 dd if=XXXX of=/dev/mtd0 

What all things I need to so to make a linux filesysem
on Disk On Chip.

I am adding part of my .config here.
