Implementation of JFFS2 File System in Embedded Linux System
Qiu Xue-hong · Computer Technology and Development · 2006
The file system is one of the important parts of an operation system.It provides a mechanism to store and manage the data for the kernel of operation system,and an access interface for the user applications.The embedded file system shall not only support the functions of a normal file system,but also satisfy the special requirements of the embedded systems.The JFFS2 file system is specifically designed for the flash devices which have been widely used in the embedded systems,and it can satisfy all kinds of requirements of the embedded systems.This paper introduces the flash memory and journalling file system in the embedded Linux system,and describes the process of porting and implementing of the JFFS2 file system based on an actual experimental platform.By using the JFFS2 file system in the embedded Linux system,can establish a good foundation for application development.
