tq210，安卓ubi文件系统使用
本帖最后由 fanqiehua 于 2013-7-4 14:49 编辑按照手册上的方法制作ubi文件系统制作烧写下去提示

加载不成功！
同样的文件系统制作成yaffs的就可以！求版主解答 把启动时的完整的串口信息贴出来。 亚瑟王 发表于 2013-7-3 09:05 static/image/common/back.gif

把启动时的完整的串口信息贴出来。
我的分析应该是UBI: logical eraseblock size: 129024 bytes，这里，本来应该是129024，你们的命令生成的文件是126976，应该在你们的文件当中增加这个参数的命令吧！ fanqiehua 发表于 2013-7-4 10:02 static/image/common/back.gif

你对比一下烧写时uboot分析ubi的信息和内核启动时分析的信息呢，都是129024这个值的。在制作镜像时也是设置的这个值。你可以用如下命令做镜像试试：
mkubifsimage -m 扇区容量(512/2048/4096) -e 块容量(129024) -c 块数量(8111) -r xxx -o xx

用了这个命令试了一下可以启动的！理论上是不是ubi的文件系统跑起来会更快些那？ fanqiehua 发表于 2013-7-4 14:21 static/image/common/back.gif

好的，那我把手册改一下。
说实话，我没有感觉出ubi比yaffs快。并且ubi如果直接关电还会出现文件丢失的情况。 亚瑟王 发表于 2013-7-4 14:31 static/image/common/back.gif
