安装依赖
sudo apt-get install qemu libncurses5-dev gcc-arm-linux-gnueabi build-essential gdb-arm-none-eabi synaptic gcc-aarch64-linux-gnu eclipse-cdt git
下载源码：
git init
git fetch https://github.com/figozhang/runninglinuxkernel_4.0.git
git checkout FETCH_HEAD

设置构架：
export ARCH=arm
设置工具链
export CROSS_COMPILE=arm-none-eabi-

@H_451_25@make vexpress_defconfig
进程arm32下创建
cd _install_arm32/@H_916_18@mkdir dev
输入
sudo mknod console c 5 1
然后编译@H_916_18@make bzImage -j 4

输入@H_916_18@make dtbs
