Tiny210 android2.3源代码编译出现了问题

1)    我用./build-android批处理文件编译android2.3源代码，出现了以下问题
find: `frameworks/base/frameworks/base/docs/html': No such file or directory
find: `out/target/common/docs/gen': No such file or directory

怎么解决啊

我要用210的gpio的外部中断接受一个40Mbps速率的通信数据，请问速度够么

无视他，让他继续工作即可

不行，很多头文件找不到，出错了，而且我的yum用不了啊，帮我看看
