Hi,
I'm just trying to install DiskOnChip MD2202-D256 flash disk on my
2.4.21-rc2 linux. While loading modul by command
'modprobe docprobe'
these messages occurred on my screen:
DiskOnChip Millenium found at address 0xE0000
Unknown flash chip found: 21 21
Please report to dwmw2@infradead.org
Unknown flash chip found: 21 21
Please report to dwmw2@infradead.org
Unknown flash chip found: A1 A1
Please report to dwmw2@infradead.org
No flash chips recognised.
This flash disk was formated by DOS command:
dformat /win:e000 /s:doc514.exb
and that enabled C:\ disk under DOS.
DiskOnChip is a part of ICOP-6070 PC/104 Embedded CPU module.
Is there some HOWTO showing me how to install this DOC in Linux?
Is this DOC supported by MTD drivers in 2.4.21-rc2 kernel?
Thanks,
Oskar

Hi all,
Sorry for a bit longer email, please be patient while reading and try to
help me if can...
I changed the DiskOnChip 2000 MD2202-D256 chip to an older 8MB
DiskOnChip 2000. (May be the MD2202-D256 model ist newer than the
drivers and so it is not supporter yet) Now I am able to see the
/dev/nftla device with /dev/nftla1 partition on my 8 MB flash disk.

Here is the order of steps I made to get funtional that 8MB flash disk:
- I built new linux kernel with MTD support. Here is the partion of my
.config file:
#

#

CONFIG_MTD_DEBUG_VERBOSE=0

#
# NAND Flash Device Drivers
#
CONFIG_MTD_NAND=y
# CONFIG_MTD_NAND_VERIFY_WRITE is not set
CONFIG_MTD_NAND_IDS=y
- by MS DOS program I formated the chip:
dformat /win:e000 /s:doc514.exb /empty /y /nodos
- and booted my newly created kernel. Some output while processing the
kernel booting follows:
Using configured DiskOnChip probe adress 0xe000
DiskOnChip 2000 found at address 0xE000
Flash chip found: Manufacturer ID: 98, Chip ID: E6 (Toshiba:NAND 8MB 3,3V)

NFTL: UnitSizeFactor 0x00 detected. This violates the spec but we think we know wat it means...
Partition check:

- then I partitioned the flash disk:

- I created an ext2 filesystem on /dev/nftla1 partition and transfered
my minimalised linux 'distribution' on that partition. (I created a
linux system that can fit under 8 MB following the Linux BootDisk
HOWTO)
- the following step was to build GRUB with DiskOnChip support:
wget ftp://alpla.gnu.org/gnu/grub/grub-0.92.tar.gz
tar xzvf grup-0.92.tar.gz
cd grup-0.92
cat ../mtd/patches/grub-0.92-doc.patch |patch -p1
aclocal
automake --add-missing
autoconf
./configure --enable-diskonchip-2000 --enable-ext2fs \
--disable-ffs --disable-xfs --disable-jfs \
--disable-vstafs --disable-reiserfs \
--disable-minix --disable-fat
make
- compilation was successful. After that all I loaded grub_firmware into
flash disk typing in MS DOS environment:
dformat /win:e000 /bdkf0:grub_f~1
Regarding the outputs from dformat, this command ended successfully.
Finally I rebooted my computer by turning the power off and on again.
Now I can see loading grub from flash disk, by it crashes by following
error:

I would suggest trying the latest GRUB patch: grub-2003-01-08-doc.patch. This
has numerous changes/improvements over the 0.92 patch.

Make sure /boot/grub/menu.lst exists or is a link to grub.conf in the
same directory. Try the kernel line with a slightly different path:
kernel (dc0,0)/bzImage root=/dev/nftla1. In any case it looks like a
path problem to me.

I was not able to patch on version 2003-01-08. Send me
grub_firmware for this version, if you can, please.
Thanx you for your help
