摘要 设计了一个基于S3C2410片内SDI的SD/MMC卡驱动,该驱动支持MMC卡、SD卡、SDHC卡。在分析SDI特点和有关寄存器功能的基础上,完成了SD模式下的硬件接口设计。介绍了该驱动的软件实现,重点分析了卡识别过程。详细阐述了该驱动的技术实现细节。该驱动通用性强、易移植,已被应用到MP3等产品中。 An SD/MMC driver based on the on-chip S3C2410, which supports MMC, SD card and SDHC card, is designed in this paper. The hardware circuit for SD mode is implemented by analyzing the features of SDI and those related registers. The software driver is also introduced and the procedure of the card identification is emphasized. Technical details for the driver are described. The driver is commonly used and easy to be transplanted and has been applied in the prodncts like MP3.
