由于内核里没有yaffs2文件系统生成功能,所以需要添加补丁。   1. fsMakefile.path in fs_yaffs2.tgz is the patch for kernel/fs/Makefile   在 kernel/fs/Makefile中添加如下内容 [root@localhost fs_yaffs2]# cat fsMakefile.path

[root@localhost fs_yaffs2]#   最后后拷贝 yaffs2/ 到 /kerenl/fs/ 中。   3. stlinux23-host-yaffs-utils-1.0.0-3.i386.rpm is to install  /opt/STM/STLinux- 2.3/host/bin/mkyaffs2image to create yaffs2 fs image.   制作文件系统工具 [root@localhost fs_yaffs2]# rpm -ivh stlinux23-host-yaffs-utils-1.0.0-3.i386.rpm --nodeps --force 这样就可以用mkyaffs2image 来制作yaffs2文件系统了~
