摘要
提出在基于移植μC/FS到ARM9嵌入式系统的基础上,编写嵌入SD卡驱动,实现基于SD卡的嵌入式文件系统。系统利用ARM9(S3C2410)内建的SPI接口实现与SD卡的接口设计,构建SD卡在μC/FS下的开发框架,给出具体实现步骤与关键代码。实验结果表明系统具有良好的性能。
This paper proposed a solution of SD card-based embbed file system by adding SD card driver to μC/FS which was migrated to ARM9 embedded system.The SD card interface with ARM9（S3C2410） is designed with SPI port which is integrated in ARM9,Concrete realization course and key codes of the development framework were given,the practice show that the system has a good performance.
