Problem using DOC with mtd

[Yves CLOUSIER]

Hi all, 

I have 5272 plateform with the 20030305-uclinux-dist. 
In this plateform I have a disk-on-chip millenium module MD2802-D08. The DOC
is map at 0xE0000000.

But during booting, I have the message :
Possible DiskOnChip with unknown ChipID 00 found at 0xe0000000
No recognised DiskOnChip devices found

In the Doc_Check() fonction in probe.c I make a memory dump of the DOC (from
0xE0000000 to 0xE0002000), see the attach file.
I think that the acces of the DOC is correct because I see the DOC bios
singature at 0xE0000000. But I don't understand why the mtd doesn't
recognised the DOC. So if you have an idea ......


Thanks.
