Pb with DOC millenium Plus 64MB

[Pascal Fifre]

Hi, 

 

I’m developping a board with a DOC Millenium Plus 64MB. I use a 16 bits
Access on a MPC5200 to dialog with it.

I modify the doc2001plus.c to do that (only 8 bits access has been supported
for now).

I’ve formatted the DOC with the msysteme Dformat utility.

The doc2001plus and inflmount driver recognized the DOC.

But only the first 1024 blocks has been correct. The doc2001plus can’t read
the 1024 other blocks.

It seems to be wrong to access on the 1024 others blocks.

I have these messages when Linux boot:

Is anybody works on it or have an idea to help me?

 

Thanks a lot.
