Abstract: This paper presents the realization of mix file system based on embedded Linux. This file system realizes data dynamic and static storage over different storage media based on several popular file system of embedded Linux, which matches the different storage requirement as well as optimize the system storage resources. This paper describes the details to design each module and the method to build the mix file system. The result shows that this mix file system is superior to those single file systems and has the advantage of optimized structure and good performance, which can fully meet the system requirements.
