摘　　要：在嵌入式Linux系统中,为了在没有PCMCIA控制器的情况下仍然要利用CompactFlash存储卡(简称CF卡)作为存储设备,从CF卡的硬件特性入手,在系统层基于CF卡的memory寻址访问方式来改造CF卡的低层驱动,并在应用层实时管理CF卡的热插拔事务,最终实现了一个利用CF卡作为方便快捷的存储设备的嵌入式Linux系统。In order to use the CF card as a storage device in the embedded linux system while there is no PCMCIA controller, the hardware characteristics of the CF card is first introduced, and then the low level driver of the CF Card is rebuild based on the memory addressing mode in the system layer and also a real-time management to the hot plug affairs of the CF card is made in the application layer. Finally, an embedded Linux system is realized, which uses the CF card as a convenient and quick storage device.
