Re: SD Driver in Wince 5.0 CMD6 not issues

CE5 does support SDHC. The support came in a QFE a few months back. Update
your QFEs to the latest and you should be fine. Note that you have to
install them cumulatively, you can't pick and choose which ones you want.

Also, CE6 didn't introduce support for SDHC until the R2 release. That came
well after the CE5 updates. So CE5 had it before CE6 did.

Hi ,
I want to add SD\MMC HC support onto WinCE 5.0, As i undertand
Microsoft bus driver for WINCE 5.0 does not support HC, only from WINCE 6
i
guess HC support is present, Is there any way i can add SDbus2.dll in my
WINCE 5.0?
I have made the changes in Host controller for HC, but if SDbus does not
support , how do i go about?
Really appreciate your help

Hi,

I am developing the host controller driver for SD Host Controller.
Although everthing seems to work fine but i have 1 doubt.

When i plug in SD Memory Card, the controller interface is set to
25Mhz, 4Bit mode. But the call for CMD6 does not come from the SD Bus
Driver Stack (i.e. for switching the Card interface to high speed
mode).

I am using SDBus2.dll.

I checked out the SDBus code in the wince500\public\common\oak\drivers
\sdcard\sdbus: But it is all confusing.

Please help.
