zynq运行操作系统之linux kernel编译

1、下载linux kernel源码

git clone https://github.com/analogdevicesinc/linux.git
cd analogdevicesinc
git checkout 2014_R2
暂且切换到分支2014_R2,其内核中的驱动可以和现有设备树对上。对于较新的内核源码，编译后在板子上没跑起来，水平不够，暂时先不研究了。

2、设置环境变量 ARCH和CROSS_COMPILE

export ARCH=arm
export CROSS_COMPILE=arm-xilinx-linux-gnueabi-

3、配置kernel编译设置

make ARCH=arm zynq_xcomm_adv7511_defconfig
或者使用
make menuconfig手动配置

4、编译

make -j8 ARCH=arm uImage LOADADDR=0x8000

然后拷贝出arch/arm/boot/uImage 到SD卡即可
