eMMC 8bit?

I am using an eMMC flash device on SDHC #2 connected in 8 bit mode.

Looks like high speed is supported (48MHZ) but only in 1 bit and 4 bit data modes.

Is it true 8bit is not supported?

Any plans on adding 8 bit MMC support?

    Hi David,

    WinCE 6.0 SDHC mdd driver does not support 8bit mode. You have to pull mdd driver src to your BSP and need to debug and verify with SD card specification to 8 bit support.

    There are not much changes if you read the specification carefully.

    Best luck..
