Abstract : 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.
