Problem with DiskOnChipMillenium

Problem with DiskOnChipMillenium

[Sanal Kumar]

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.

Try using the following options:

# Memory Technology Devices (MTD)
CONFIG_MTD=y
CONFIG_MTD_DEBUG=y
CONFIG_MTD_CHAR=y
CONFIG_NFTL=y
CONFIG_NFTL_RW=y

# Disk-On-Chip Device Drivers
CONFIG_MTD_DOC2000=y
CONFIG_MTD_DOCPROBE=y

(turn off CONFIG_MTD_DOC2001, and CONFIG_MTD_DOCPROBE ADDRESS).

Sorry, I've never seen those type of error messages before.

It may be worth a try to completely reformat the DiskOnChip using the 
M-Systems DOS utilities:

http://www.m-sys.com/content/download/OSSupport2.asp?id=8&pid=2

Whenever my DoC had problems, the DFORMAT utility was usually able to get it 
back to a known state.

Unless you're using newer code from the MTD CVS archives, you'll want to use 
version 4.2 of the utilities.

These instructions show how to install the Grub bootloader on a DoC, but 
there is some general information about using DFORMAT and installing a Linux 
filesystem:

http://www.lakeshoremicro.com/diskonchip-grub-howto.html

I hope this helps.
