Software Requirement && DiskOnChip

Software Requirement && DiskOnChip

[Ara Avanesyan]

Hi,

  Everywhere in DiskOnChip files there are referneces to a magic "Software
Requirement 11.x.y".
Can someone please tell me where can I locate one?

  Also, where can I find the descriptions of the registers
DoC_Mplus_FlashControl through DoC_Mplus_WritePipeTerm
defined in doc2000.h? The data-sheet for MPlus DOC device does not contain
this info.

__
Thanks,
Ara

Unfortunately I don't think these are publicly available. Although I
have a vague recollection of being corrected last time I said that.

David,

Thanks. I'll contact M-System for the document.
Bah! This somewhat violates my [very basic]
understanding of open source community. It's 
something like "open source and close source of 
source". Couldn't the driver writer (you:)) put the
document to the source tree documentation part?

Thanks,

I don't think so.  The source code is definitely open source.  The
hardware documentation is whatever the vendor decides it should be.  In
this case, M-Systems decided that it should not be public, IIRC.

ok,

My question is from theory only:)
Can't then the driver writer copy-paste the documentation to source files as
comment? really...
And what could be the reason to not sharing the hardware documentation to
the community???

The legal papers signed before receiving the documentation.  In some
unfortunate cases, people get documentation und "You may not show
anyone!" style licenses.  With that, the alternatives are either
drivers without hardware documentation or no drivers at all.

Not if there is an agreement with the documentation owners to not
release the documentation.  That would be similar to taking a
programming book and pasting the contents into a program you wrote using
information in the book.  It's known as plagiarism.

I have no idea.  You'd have to ask M-Systems I guess.

(btw, top-posting is frowned upon on this list.)

Josh,

Thanks for clarifications.

Sorry about that. I'll keep this in mind for the future.

On what DiskOnChip are you working? At the moment I'am trying to
extend diskonchip.c to support the Millennium Plus 32MB. If you are
doing the same, please let me know.

Actually I'm going to make it work for DOC G3.
