现在所要的文件基本上已都有了，怎么样来放到SD卡里来让系统运行起来呢？
这里主要介绍Linux下面的方法，Windows下面用工具分就不说了。
sudo fdisk /dev/sdx(这里根据实情情况来) fdisk 的使用在网上找。这里主要是建立两个分区。
然后进行格式化，一个FAT32格式，一个EXT4格式。

这里用的文件系统是直接用的zedboard里面带的，直接用是用不了的，简单改名也行不能，那么怎么办呢？

到这一步，基本上就离成功不远了，我就不一一分析了http://blog.csdn.net/luhao806/article/details/7338465，但直觉告诉我，应该是串口没有设对。所以我直接去到内核源码中，修改dts文件，直接将串口1改为0，然后 重新生成devcietree.dtb文件，然后替换掉SD卡里面的就OK了。下面是完整的打印信息。
