Hello All,
Are there any compact flash driver supported for Linux 2.6? If there is
where can i get the source code.
Thanks,
Bizhan

I think that CF cards just get treated the same as any other IDE
disk by linux.  No special driver needed.

  Yes. There are some gotchas with newer pcmcia/cardbus flash cards.
For instance, Silicon Systems devices claim to support IORDY, but don't,
which results in a system hang.  I imagine that the same kind of things
will show up in newer CF devices, although I think that CF can't support
DMA.
  It also depends upon how you interface CF: via an IDE controller, or
via a cardbus interface.

  I expect to have a git tree with stuff available soon.

Do you have an early release code? I can start to work at.

Many thanks in advance,

  I have to merge code into the torsvalds tree still.
  Priority goes to actually shipping our product :-)

Ask more specific question as to what hardware platform you are using.
Specifically, which CF controller....

 Hardware platform is dm320. Specifically is CF 3.0 memory mode.
