摘要
本文介绍了基于Intel PXA255与ARM-Linux的嵌入式系统下的USB移动存储器设备的设计,对PXA255内嵌的USB设备模块的Linux驱动程序结构进行了详细分析,通过Linux下MTD的块设备与USB Mass Storage Class协议实现了在该系统上的USB移动存储器。
This paper describes the design of portable USB mass storage devices in the embedded system based on Intel PAX255 and ARM-Linux, and analyzes in detail the framework of the Linux device driver of the USB device module in PXA255. By using the block device provided by the MTD of Linux and the protocol on USB Mass Storage Class, we achieve the USB portable storage device in this system.
