第二步，将下载下来的YAFFS2最新源码 YAFFS2.tar.gz 放入你Linux的任意一个目录下，执行 tar zxvf YAFFS2.tar.gz 然后进入YAFFS2源码包，由于最新的源码再执行脚本 patch-ker.sh（具体方法见此目录下README-linux-patch） 时 有四个参数，可以追加：c,l,m,s,

./patch-ker.sh  c/l m/s kernelpath

if c/l is c, then copy. If l then link

if m/s is m, then use multi version code. If s then use single version code

上面这段英文应该很好懂吧，简而言之，C 是复制文件，L是链接文件，M是多种，S是单个的

xiao@urbetter-ubuntu:~/linux-3.6.6$ ./patch-ker.sh c m ../linux-3.6.6    即可！

 

第三步：配置（make menuconfig）
