摘要
本文首先介绍了JFFS2,FLASH和MTD的相关知识。之后详细介绍了如何利用MTD技术在flash上实现JFFS2文件系统。包括驱动程序鳊写,内核修改和配置,根文件系统的建立。最终使得JFFS2文件系统可以稳定、可靠地运行在ARM920开发板上。同时也指出了JFFS2的局限性和发展趋势。
This paper firstly introduces some basic knowledge about JFFS2,FLASH and MTD.Then we introduce how to realize the JFFS2 file system with MTD technology on flash in detail,including device driver,kernel configuration and root file system building.Finally we make the JFFS2 file system run stably and reliably on ARM920T board.Some defect and trend of JFFS2 are also discussed in this paper.
