在Zedboard上构建 Android 有三个步骤：
1.准备开发环境。
2.构建 Linux 内核
3.构建 Android 用户空间
4.准备引导 SD 卡
硬件需求
The ZedBoard: is an evaluation and development board based on the Xilinx Zynq 7000. Combining a dual Corex-A9 Processing System (PS)equipped with 85,000 Series-7 Programmable Logic (PL) cells;
A monitor capable of displaying VESA-compliant 1024x768 @ 60Hz with
an analog VGA input (i.e. PC monitor);
An analog VGA cable for the monitor;
A USB keyboard;
A USB mouse;
A USB hub recognized by Linux 3.3.0, if the keyboard and mouse are not
combined in a single USB dongle;
A SD card with 4GB or more (we suggest a Sandisk one);
A PC with slot for SD cards
软件需求
Operating System: Linux Mint Debian Edition
Xilinx ISE 14.4 and the CodeSourcery Lite ARM cross compiler toolchain (Xilinx edition included with ISE).
The Android compilation needs the Oracle Java Development Kit, version 1.6. More recent versions (for example 1.7) can’t be used. Building with OpenJDK is not recommended.
The easiest way to build Android is using the 4.4 version of gcc.
For building Linux and Android the Linux host system is mandatory, but you can use your preferred Linux distribution. Building in a virtual machine is not recommended because of the high hard disk space and memory usage.
