基于S5PV210的android系统移植日记。

这样烧写到实际的目标机上，测试没有增加进去呀，后来执行：make -j1 PRODUCT-sec_smdkv210-eng snod 就增加进去了。system.img文件变大了。
今天测试发现：没有选上声卡模块的内核，android会启动不到桌面！

今天终于找到不能下载android4.0问题的原因了：git工具有问题，我卸载后重新安装git工具就可以下载android4.0了。

一直以为是system.img文件系统的原因，或者是烧写system.img的不成功原因才导致上面找不到/system/bin/下的很多命令找不到。今天分析出原因了：
是system分区里坏块很多，已经达到640块坏块，几乎达到整个分区的大小了，所以报：yaffs tragedy: no more erased blocks。所以才找不到后面的文件。其实它是有写进去system.img的，只是写得很后面去了，造成系统yaffs读文件系统错误。这一点上我看也是android系统yaffs文件系统的一个BUG吧？！不应受分区大小的限制，若有坏块要一直往后读。

现在已经移植好uboot1.3.4了，内核linux2.6.32.9也已经能正常跑起来了，能显示linux企鹅图标，后来出现了android的动画图标。但是没有进入到桌面。启动到如下地方停止：不知是android代码问题还是kernel代码问题。

今天在虚拟机上执行上面下载android源码的命令时老是出现403错误，不知为什么？谁遇到过？
