摘　　要：随着嵌入式系统的发展,使用Linux操作系统搭建的嵌入式平台得到了越来越广泛的应用。文件系统是嵌入式Linux系统的重要组成部分,一个合适的文件系统解决方案可以极大的提高系统的性能并充分利用系统资源。本文介绍了几种常用的嵌入式Linux文件系统,在对其优缺点进行分析的基础上,提出了一种兼顾系统安全性与灵活性的文件系统解决方案,并详细说明了实现该方案的具体步骤。With the development of embedded system, the embedded platform using Linux has got more and more extensive application. The file system is the important component of an embedded Linux system, and a suitable file system may greatly improve system＇s performance and fully utilize system＇s resources. In this paper, we introduce several kinds of common file systems used in embedded Linux and analyze its advantage and shortcoming. Then we have proposed a kind of solution which can give consideration to system＇s security and flexibility at the same time. In the end, the detailed steps of finishing the scheme are interpreted.
