摘要
介绍了CF卡的基本结构和工作原理,然后在基于ARM7TDMI内核的SEP3203嵌入式处理器的嵌入式系统中,利用Altera公司的CPLD芯片EPM7032成功实现了CF卡接口的扩展,提供了在μClinux下的CF存储卡驱动支持.本文的CF卡接口方案为本身不带CF卡控制器的处理器扩展CF卡接口提供了一个参考.
This paper introduces the structure and principle of CompactFlash Card.We success to implement a CF Card interface using the CPLD chip EPM7032 produced by Altera company in the embedded system which is based on an ARM7TDMI-Based Embedded Processor—— SEP3203,and we also develop the CF storage card device drive on μClinux Operation System.The method introduced in this paper gives a good reference to extend CF interface for those processors without a CF controller on chip.
