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 =3D 0x98 and Id =3D 0x75) were recognized too. =20 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?
