Hi,
sdbus2.dll has been supplied to support high capacity and high speed cards
in wince6.0. Does it actually supporting the HC and HS features. has anybody
tested those features. In my case I tested SDMemory High speed card but the
card is not coming to high speed. it was running on normal speed.
Does sdbuss2.dll also support 4bit and 8 bit mode for MMC? I saw the code it
is doing nothing means not switching the bit mode for MMC case.
Can anybody comments on this?
Thanks
Talib
Windows CE6(R2 added) support HC and HS for SD card, but HS can't work
through my test.
you need to add switch function before set four bit mode( just like
ce5 do).
For MMC, only support MMC4.0-, that means you can 1 bit mode, and
24Mhz( or lower, I am not very sure)
