ubuntu 16.04 QEMU 搭建跑arm架构linux内核

1, 安装qemu

    sudo apt-get install qemu

2，准备arm交叉编译环境和linux-3.19的内核源码。

    执行如下命令：由vexpress_defconfig 生成.config 

     code/linux-3.19.8$ make ARCH=arm CROSS_COMPILE=/opt/prebuilts/gcc/linux-x86/arm/arm-linux-gnueabihf-7.2.1/bin/arm-linux-gnueabihf- vexpress_defconfig

3，编译内核

    make ARCH=arm CROSS_COMPILE=/opt/prebuilts/gcc/linux-x86/arm/arm-linux-gnueabihf-7.2.1/bin/arm-linux-gnueabihf- 

4,启动kernel

qemu-system-arm -M vexpress-a9 -m 512M -kernel ./arch/arm/boot/zImage -dtb  ./arch/arm/boot/dts/vexpress-v2p-ca9.dtb -nographic -append "console=ttyAMA0"
