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

2. Kconfig.patch in fs_yaffs2.tgz is the patch for kernel/fs/Kconfig
在 kernel/fs/Kconfig中，添加如下内容

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~
4. use apply_yaffs2nand-app.sh
[root@localhost hanbang--mini+fs+for+ramdisk&jffs2&yaffs2]# cat apply_yaffs2nand-app.sh
echo "rm ./yaffs2fs-app.yaffs2"

echo "done !!!"
[root@localhost hanbang--mini+fs+for+ramdisk&jffs2&yaffs2]#
5. 制作文件系统：source ./apply_yaffs2nand-app.sh
