DiskOnChip Millennium Plus 32MB

DiskOnChip Millennium Plus 32MB

[Peter Bergmann]

i have an embedded x86 device with a trueffs DiskOnChip
Millennium Plus 32MB on it.
the first thing i've tried was the semi-binary only
driver from m-systems (doc.o) with kernel 2.6.11.
the chip was only detected when specifying the fl_winh
module parameter in order to increase the default probe
window size.
but the driver does not really work. each time i run
md5sum on a file or the device itself (/dev/fla)
i get a different checksum! i've tried the same driver
with a doc2000 16MB and a millennium 8mb and it worked
without problems.

i was glad to find the following message on your project
homepage:
"The DiskOnChip 2000, Millennium and Millennium Plus
devices should be fully supported, using their native
NFTL and INFTL 'translation layers'."

but i've not been able to get it running:

the devices/doc2001plus.c recognizes the device but the
inftl.ko says:
"INFTL no longer supports the old DiskOnChip drivers
loaded via docprobe. Please use the new diskonchip
driver under the NAND subsystem"

great but this combined nand/diskonchip.c driver tells
me "DiskOnChip Millennium Plus 32MB is not supported,
ignoring."

what do i have to do in order to get a
trueffs formatted DiskOnChip Millennium Plus 32MB
running under linux ?

please cc me as i'm not subscribed to the list yet.

thanks for any hints!

cheers,
pet.

Up to now that diskonchip driver supports everything except the
"DiskOnChip Millenium PLus 32/64MB", and the old driver doesn't work
with the mtd subsystem.

A new driver for the DiskOnChip Millenium Plus 32/64MB is nearly
finished. I can send you some patches for testing.

Can attach to mail in a tar.bz2 ?
Or give an URL to grab it.


I can test it over PXA250 with 2.6.11.

 And olso i done a tool wich use mtd as backend and openjtag as frontend
to easily manage/dump/flash over JTAG cable ! This piece of code was missing 
for me for these MTD models :)

	This would be great help for lots of PDA models, and for JTAG engineering
of these flashes.

DiskOnChip Millennium Plus 32MB

[Mark Salter]

I have a box with a Millennium Plus 64MB part (MD3331-D64-V3) which is
really just two 32MB parts on the same die. I'm not having much luck
with mtd, though. If I use docprobe/doc2000plus/inftl, I get a message
from inftl saying that the old (doc2000plus) driver is not supported and
I should use the diskonchip driver under the nand directory. This was
discussed a couple of years ago and a patch was claimed to be nearly
ready:

  http://lists.infradead.org/pipermail/linux-mtd/2005-May/012592.html

The current nand/diskonchip.c has this:

  case DOC_ChipID_DocMilPlus32:
    printk(KERN_ERR "DiskOnChip Millennium Plus 32MB is not supported, ignoring.\n");
  default:
   ret = -ENODEV;
   goto notfound;

So it seems the 32MB support never showed up. Am I missing anything? Was
the patch ever submitted?
