摘　　要：介绍了JFFS2文件系统以及与其相关技术,分析了与μClinux内核接口的关键函数。然后以NOR Flash芯片SST39VF6401B为例,详细介绍了如何构建JFFS2文件系统的关键过程。主要涉及相关源代码和重要数据结构的分析和修改,内核的配置过程以及JFFS2文件系统镜像的制作和挂载的方法。实际测试结果表明了该移植的正确性。The JFFS2 file system and its related techniques are introduced. Some key functions related to the μClinux kernel-interface are analyzed. The establishment of the JFFS2 file system on the NOR-Flash chip SST39VF6401B is discussed in detail. The main contents include some modifications of the source code and related data-structure, some configurations of the μCllinux-kernel, as well as the file system image making and mounting methods. The results show the correctness of this transplant.
