does anyone here used Ampro modules?

[Nick Maximov]

Is there specific conditions for using MTD drivers with Ampro CM/p5e?

I still trying to figure out how it should work. Ampro said NEVER USE
ORIGINAL
M-SYSTEM UTILITIES TO FORMAT DOC!!!
Does MTD utilities compatible with my hardware or I need special tune for
them?

I tried though... And got BIOS corruption :) After first sucessful recovery
I tried to
load alternative firmware file (grub.exb) to DoC firmware area. Now my DoC
even unable to be formated!

Does anyone knows what is exact address map for DoC device?
As I know BIOS occupied 128K at 0xE000,
user extention BIOS located at 0xD000 address and should occupied up to 64K.
And then where the Flash Firmware is located? Why p5update utility unable to
update exact area in memory space?

How did you make 'grub.exb'? I haven't written any tool to produce EXB 
files from the Grub images - I only write them to the flash with my own 
doc_loadbios utility.

Load the docprobe and doc2000 modules under Linux - it'll probe all the 
possibilities and tell you where it's mapped in your particular board.

The DiskOnChip firmware is at the beginning of the first flash chip in the 
DiskOnChip. As it's NAND flash, it's not memory-mapped directly.

You _have_ read the NAND flash datasheets, haven't you?
