DiskOnChip MD2202-D256

[Oskar Stolc]

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

Possible GRUB problem: [Was: DiskOnChip MD2202-D256]

[Oskar Stolc]

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:

  	#
	# Memory Technology Devices (MTD)
	#
	CONFIG_MTD=y
	CONFIG_MTD_DEBUG=y
	CONFIG_MTD_DEBUG_VERBOSE=0
	# CONFIG_MTD_PARTITIONS is not set
	# CONFIG_MTD_CONCAT is not set
	# CONFIG_MTD_REDBOOT_PARTS is not set
	# CONFIG_MTD_CMDLINE_PARTS is not set
	CONFIG_MTD_CHAR=y
	# CONFIG_MTD_BLOCK is not set
	# CONFIG_MTD_BLOCK_RO is not set
	CONFIG_FTL=y
	CONFIG_NFTL=y
	CONFIG_NFTL_RW=y

	#
	# RAM/ROM/Flash chip drivers
	#
	# nothing is set

	#
	# Mapping drivers for chip access
	#
	# nothing is set

	#
	# Self-contained MTD device drivers
	#
	# CONFIG_MTD_PMC551 is not set
	# CONFIG_MTD_SLRAM is not set
	# CONFIG_MTD_MTDRAM is not set
	# CONFIG_MTD_BLKMTD is not set
	# CONFIG_MTD_DOC1000 is not set
	CONFIG_MTD_DOC2000=y
	# CONFIG_MTD_DOC2001 is not set
	CONFIG_MTD_DOCPROBE=y
	CONFIG_MTD_DOCPROBE_ADVANCED=y
	CONFIG_MTD_DOCPROBE_ADDRESS=E0000
	# CONFIG_MTD_DOCPROBE_HIGH is not set
	# CONFIG_MTD_DOCPROBE_55AA is not set

	#
	# 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:
	 nftla: nftla1

- then I partitioned the flash disk:

	# fdisk /dev/nftla
	Command (m for help): p
	Disk /dev/nftla: 8 MB, 8101888 bytes
	16 heads, 1 sector/track, 989 cylinders

		Device	Boot	Start	End	Blocks	Id	System
	/dev/nftla1		1	989	7911+	1	Linux

	Command (m for help): w

- 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:

:-(

What am I doing incorrectly?

All suggests are welcome.

Thank you,

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

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

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.

You should format the DOC with driver 4.2: 
dformat /win:e000 /s:doc42.exb
and try to use MTD driver or you must use linux driver
ver4.2 from M-sys

diskonchip md2202-d256

[Sarah Diesburg]

My research group is experimenting with diskonchip, and we have two of
the DoC 2000 256MB DIPs.  We eventually would like to mount ext3 on top
of inftl in Linux.  We are using a 2.6.25.6 kernel, and we have grabbed
the latest mtd utilities from the git repository.

We have had a hard time coming by a how-to with the latest kernels and
modules, so I wanted to post our proposed methodology here.  Does the
following sequence of events look right?

1. modprobe diskonchip

2. go into the mtd-utils directory and run the "MAKEDEV" script to
create the /dev/mtd* entries and the /dev/inftla entries.

3. ntfl_format -i /dev/mtd0

4. modprobe inftl

5. fdisk /dev/inftla and partition as a disk

6. mkfs.ext3 /dev/inftla

7. mount -t ext3 /dev/inftla /mnt

Thanks for your help!
