Abstract

The embedded file system is an important part of embedded operating system. Due to the particularity of embedded devices storage medium, the instability of power supply and the security of mobile storage, the embedded file system has increasingly obvious importance in the embedded operating system. Based on the analysis of the realization plan of traditional Li ~ file system and several current popular embedded file systems, the paper proposed the realization plan of embedded Linux file system. The paper took the IntelDBPXA250 experiment and development platform as the hardware platform. The main part of the paper described the realization of one embedded Linux operating system on the hardware platform, and laid the background for later file system realization. Then, this paper analyzed the design logic of the three levels, VFS, JFFSZ and MTD, and proposed the overall design frame of embedded file system. Afterwards, the paper described the practice details of Flash file system based on MTD equipment in embedded Linux. Considering the limitation of embedded devices storage space, on the basis of the embedded Linux file system, the paper simplified the corresponding virtual file systems and physical file systems that construct the file system, and made them more satisfactory to the requirement of embedded equipment.
