Sample Secure Digital Card Driver

  • Article

The sample Secure Digital card driver supports both MultiMedia Card (MMC) and Secure Digital (SD) cards and is designed for a PCI-based card developed by SanDisk, part # SDSDEV-01. The MMC supports unsecured storage. The SD card has both a nonsecure and a secure area. The nonsecure area is 90 percent of the space; the remaining 10 percent is secure. This driver only supports the nonsecure portion of the SD card.

Polling the socket approximately once per second detect insertions and removals. When the state changes, the socket driver notifies and updates the file system.

The sample Secure Digital card driver exports a stream interface with the DSK prefix and the block device driver interface. For more information about the stream interface, see Stream Interface Drivers.
