[讨论] 为什么我明明按照三星的官方文档把yaffs 改成ext4文件系统，但是生成的还是yaffs

3.050782] yaffs: dev is 32505860 name is "mtdblock4" rw

烧写进SD卡和inand ，一直提示下面的信息

后来看android 下的build/core/makefile 居然没调用ext4 制作工具！汗，估计是这里了搞了我半天了。
init.rc 删除了yaffs mount 也不行。

on fs
# mount mtd partitions
    # Mount /system rw first to give the filesystem a chance to save a checkpoint
    mount ext4 /dev/block/mmcblk0p2 /system
    mount ext4 /dev/block/mmcblk0p2 /system ro wait remount
    mount ext4 /dev/block/mmcblk0p3 /data wait nosuid nodev noatime
    mount ext4 /dev/block/mmcblk0p4 /cache nosuid nodev noatime

问题已经解决，这个应该算是我经验不足。
也算是android2.3.1 的一些功能做的不足，不如android2.3.4 智能化。
老的init.rc文件是在android2.3.4 上会自动更新，但是在android2.3.1 上却不会的！，所以比较坑爹。
所以在android2.3.1 上需要手动删除init.rc 文件，然后重新在root 目录生成init.rc 就是新的有效的文件了。坑爹啊，不过这个玩意比较OK，还是比较正常，把问题给解决了。呵呵，Sate210 现在支持inand 和SDMMC 运行，烧写，真是太棒了。wince和android双系统，稳定运行了！
