Hello, I have a standard IDE harddrive connected to a
Compact Flash port. I believe winCE should be able to
support this but not sure how to get it working.
HARDWARE:
-PXA250 with SA1111 (based on Intel Lubbock dev board)
-Connected A[2:0], D[15:0], IOWR, IORD, CE1, CE2, IOIS16,
RESET, nIRQ to corresponding pins on SA1111.
-Forced CD1 & CD2 low so winCE knows something is on Sock1
SOFTWARE:
-winCE 4.2 using BSP provided with 4.2 for Intel Lubbock
-Included in build : storage devices -> ATAPI PCI/IDE
storage block driver, Compact Flash / PC Card Storage
-included everything under "storage manager" in build
RESULTS:
-winCE comes up with dialog box to enter driver for device
on socket 1. Not sure what to put here.
The compact flash spec allows for devices operating
in "true IDE" mode so this must be possible. Is there a
proper driver for this in winCE 4.2?

Jeff,

What is the "bus" that the CF card is hooked to? If it is PCMCIA/PC
Card then you'll have to load the PCMCIA driver along with the ATADISK
driver and appropriate registry entries.

I believe ATAPI only works with a PCI bus (its PCMCIA section is
commented out).

This won't work. A CF card is not the same as an IDE disk. CF is really just
a subset of PCMCIA. so there is a PCMCIA controller in there. What you have
described is hooking up and IDE disk directly to a PCMCIA controller
obviously that will not work. You need to hook it up to an IDE controller or
you need to hook use a CF/PCMCIA adapter to connect to it. (I don't think
such a thing exists.)

The CF spec _ALLOWS_ for TRUE IDE mode but does not _REQUIRE_ it for every
CF slot. If it is used it is hard wired that way in the _slot_ thus you
cannot just hook up an IDE device to any CF slot.
