摘要：为在嵌入式系统中实现数据的动态操作，通过对MTD子系统和JFFS2文件系统的移植，完成了对Flash的动态操作和管理。介绍了针对MTD子系统的相关源码的分析和内核的配置。最后通过对生成的JFFS2文件系统的读写等操作的测试，验证了方法的可行性。

Abstract: For achieving operating the data dynamicly, the dynamic operation and management for flash by the good transplantation of MTD sub system and JFFS2 file system were accomplished. Modify the linux source code and configure the linux kernel in detail were introduces. At last, The feasibility of the method is validated by testing read and write operation of the modified JFFS2 file system.
