说明：本次操作的在SD使用纠结的是无意中想到了，做这次的试跑的算作是一次尝试吧，虽然最终的结果是以失败告终，但是还有很有收获的
按照的xilinx提供资料，zynq目前支持的linux系统，android系统。板子上的SD卡附带的是linux的系统，那么android在哪里了？
在wiki.xilinx.com上的提到过开源操作系统android，还提供了编译好的android的文件以及编译方法（下载地址为http://git.iveia.com/support/需要注册后才能下载）。起编译好的文件列表如下：
我们所要做的就是给SD卡分区，具体的操作如下：
所有需要的环境为Ubuntu 的操作系统，下载地址为http://www.ubuntu.org.cn/download。我所使用的12.04.
1.查询下你sd所在的盘符编号：

因为我电脑在中有2个硬盘，所以SD被分给了 /dev/sdc 的为止
2.指定到给那个设备分区;
$ sudo fdisk /dev/sdc
然后会显示
Command (m for help):接着开始分区
3.删除分区，创建分区，

已经分好2个区了，
5.接着保存分区

6.设置分区的属性
$ sudo partprobe /dev/sdc
$ sudo /sbin/mkdosfs -F 32 -n "ANDROID" /dev/sdc1
$ sudo /sbin/mkdosfs -F 32 -n "EXTERNAL" /dev/sdc1
android的文件移复制到SD中，上点启动。上面记录的是我操作的过程，最后的结果是没跑起来，看样子是boot阶段都没过。什么原因还在分析。
