摘要
Linux操作系统具有非常强的可移植性和剪裁性、被广泛应用于嵌入式系统领域。由于嵌入式系统多使用Flash存储器取代硬盘作为主存,日志型闪存文件系统———JFFS2非常适合将嵌入式Linux的文件系统建立在Flash芯片上。介绍了JFFS2文件系统的文件管理模型、物理存储格式、文件系统重建及利用MTD驱动模块在NOR型Flash器件上的实现。
Linux operation system was wildly used in embedded systems arena for its portability. Embedded systems usually use Flash memory to replace hard disk as main storage. JFFS2 is very suitable to set up embedded Linux file system on raw Flash chip. It introduces the file management mode,physical storage format,file system rebuilding operation and implementation on NOR Flash using MTD driver module of JFFS2.
