用Qemu运行/调试arm linux，这事情干过好几次了，久了就忘记了，每次都要重新去查资料，浪费不少时间。这次把整个过程弄成个脚本，放到github上，需要是拿下来运行一下即可，方便自己也方便有需要的朋友。这里解释一下脚本的内容(运行系统Ubuntu 16.04 LTS)：1. 设置一些环境变量，可以根据自己需要修改。export ARCH=armexport MACHINE=vexpressexport TARGET=arm-linuxexport GDB_VERSION=8.0export KERNEL_VERSION=4.4.1export BUSYBOX_VERSION=1.25.1export CROSS_COMPILE=arm-linux-gnueabihf-2. 安装工具链等软件包function prepare() { apt-get -y install qemu gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf libexpat1-dev libncurses5-dev}3. 下载Linux内核并解压function download_linux() { if [ -e linux-${KERNEL_VERSION}.tar.xz ] then echo linux-${KERNEL_VERSION}.tar.xz exist else wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-${KERNEL_VERSION}.tar.xz fi if [ -e linux-${KERNEL_VERSION} ] then echo linux-${KERNEL_VERSION} exist else tar xf linux-${KERNEL_VERSION}.tar.xz fi}4. 编译Linux内核function build_linux() { echo "build_linux ..." cd linux-${KERNEL_VERSION} make ${MACHINE}_defconfig make zImage -j8 make modules -j8 make dtbs cd -}5. 拷贝内核到独立目录function copy_linux() { rm -rf arm-linux-kernel mkdir arm-linux-kernel cp -fv linux-${KERNEL_VERSION}/arch/arm/boot/zImage arm-linux-kernel/ cp -fv linux-${KERNEL_VERSION}/arch/arm/boot/dts/*ca9.dtb arm-linux-kernel/ cp -fv linux-${KERNEL_VERSION}/.config arm-linux-kernel/}6. 下载并解压busyboxfunction download_busybox() { if [ -e busybox-${BUSYBOX_VERSION}.tar.bz2 ] then echo busybox-${BUSYBOX_VERSION}.tar.bz2 exist else wget https://busybox.net/downloads/busybox-${BUSYBOX_VERSION}.tar.bz2 fi if [ -e busybox-${BUSYBOX_VERSION} ] then echo busybox-${BUSYBOX_VERSION} exist else tar xf busybox-${BUSYBOX_VERSION}.tar.bz2 fi}7. 编译busyboxfunction build_busybox() { echo "build_busybox..." cd busybox-${BUSYBOX_VERSION} make defconfig make CROSS_COMPILE=${CROSS_COMPILE} make install CROSS_COMPILE=${CROSS_COMPILE} cd -}8. 制作rootfsfunction make_rootfs() { rm -rf tmpdir rm -rf rootfs mkdir -p rootfs/lib mkdir -p rootfs/dev cp -Pvf /usr/arm-linux-gnueabihf/lib/* rootfs/lib cp busybox-${BUSYBOX_VERSION}/_install/* rootfs/ -rf dd if=/dev/zero of=rootfs.ext3 bs=1M count=128 mkfs.ext3 rootfs.ext3 mkdir tmpdir mount -t ext3 rootfs.ext3 tmpdir/ -o loop cp -r rootfs/* tmpdir/ mknod tmpdir/dev/tty1 c 4 1 mknod tmpdir/dev/tty2 c 4 2 mknod tmpdir/dev/tty3 c 4 3 mknod tmpdir/dev/tty4 c 4 4 umount tmpdir}9. 下载并解压gdbfunction download_gdb() { if [ -e gdb-${GDB_VERSION}.tar.gz ] then echo gdb-${GDB_VERSION}.tar.gz exist else wget http://ftp.gnu.org/gnu/gdb/gdb-${GDB_VERSION}.tar.gz fi if [ -e gdb-${GDB_VERSION} ] then echo gdb-${GDB_VERSION} exist else tar xf gdb-${GDB_VERSION}.tar.gz fi}10. 编译gdbfunction build_gdb() { echo "build_gdb..." cd gdb-${GDB_VERSION} ./configure --target=${TARGET} --enable-sim --prefix=/usr/local/ make cp -fv gdb-${GDB_VERSION}/gdb/gdb /usr/local/bin/arm-linux-gdb cd -}11. 生成gdb启动脚本function gen_gdb_init() { echo "file linux-${KERNEL_VERSION}/vmlinux" >gdbinit echo "dir linux-${KERNEL_VERSION}" >>gdbinit echo "target remote :1234" >>gdbinit}12. 汇总function build() { prepare download_linux build_linux copy_linux download_busybox build_busybox make_rootfs download_gdb build_gdb gen_gdb_init}buildecho "Done"github还包括其它一些脚本和使用说明，一并放在https://github.com/xianjimli/qemu-arm-linux上。参考资料（非常感谢）http://files.meetup.com/1590495/debugging-with-qemu.pdfhttp://blog.csdn.net/nxcxl88/article/details/53244754版权声明：本文为博主原创文章，未经博主允许不得转载。 https://blog.csdn.net/absurd/article/details/78984244
