Subject: PB with millenium plus 64

Hi,
I'm developing a controller board with a DOC plus 64 MB.
In a first time, the OS not recognize it. Then I saw in the
doc2001plus.c code, that the 16 bit access on DOC was not implemented.
Is it true?
I put my DOC in a 8 bit access and then, the OS recognize it, and the 2
FLASH chips (Mfr = 0x98 and Id = 0x75) were recognized too.
Then, when I've tried to format it with "nftl_format" on Linux. The
nftl_format told me "Unrecognized Erase size, 0x8000 - I'm confused\n".
I modify the code for accepted the 0x8000 size and retry: this operation
made an ERASE operation on DOC. Since I did it, I can't read the ID chip
of flash (Manufacturer and Id chip)? I read always 0xFF on the 2
parameters.
I think, in the same time, the LOCK pin was on. Perhaps my DOC is
locked?
In this case how can I do to unlock it?
What's wrong with DOC?
Thanks a lot
