摘要
简要介绍SD存储卡的特点,对PXA270的SD存储卡控制器进行了分析,对基于Intel PXA270嵌入式微处理器的Liod开发板的SD硬件接口电路进行了剖析,并以SD卡通信协议为基础,Liod开发板的SD存储卡接口在嵌入式Linux操作系统下驱动程序.
The characteristic of SD memory card is introduced briefly at first in this paper, then has carried on the analysis of the PXA270 SD memory card controller, afterwards the SD card hardware interface circuit in Liod development board which uses Intel PXA270 embedded microprocessor is analyzed. Finally we take the SD card communication protocol as the foundation to analyze Liod development board＇s SD memory card interface driver in embedded Linux operation system.
