Secure Digital (SD) Card Drivers (Compact 2013)

3/26/2014

Learn about adding support for Windows Embedded Compact 2013 SD card drivers, such as MiniSD, MicroSD, and regular SD.

Secure Digital (SD) card technology is a standard for storage and peripheral I/O expansion that is tailored for portable devices. SD cards provide a high data transfer rate, low battery power consumption, and storage that is portable among various devices. SD cards use flash memory to implement non-volatile storage for both read/write and read-only data. Due to the non-volatile nature of flash media, a power source is not required to retain data stored on an SD card.

The SD card driver stack for Windows Embedded Compact supports MiniSD, MicroSD, and regular SD Cards.

The operating system now supports up to version 2.0 of the SD Card Physical Layer Specification. The Microsoft SD bus version 2.0 provides a faster and more reliable SD bus implementation. Two of the features offered by version 2.0 of the SD bus are SD high capacity card support and SD high speed mode support. For additional information on the new SD bus and the benefits it offers, refer to the topics in this section.

To add this feature to your OS, see Secure Digital (SD) Card Driver Catalog Items and Sysgen Variables.

For reference information, see Secure Digital (SD) Card Driver Reference.

The recommended location for your driver implementation is %_WINCEROOT%\Public\Common\OAK\Drivers\SDCARD.

The Windows Embedded Compact Test Kit (CTK) tests that apply to this type of driver are:
