本文通过分析JFFS2 文件系统与传统文件系统的在超级块管理上的异同，提出了一 种新的JFFS2 超级块的管理方法，解决了原来JFFS2 超级块在挂载时候动态生成比较慢的
问题。尤其适合管理大容量的闪存芯片的超级块。
关键词：超级块，嵌入式系统，文件系统，JFFS2，闪存
Abstract：This paper analyses the sameness and difference in super block management between JFFS2 file system and traditional file system, then the author gives out a solution on how to avoid the problem which JFFS2 has in mounting process. The super block in original JFFS2 file system is created dynamically at mounting process, which make the process slow, especially in some Flash devices with big capacity. In the new solution the super block finding speed is faster.
