一键编译并启动一个 ARM Linux qemu 虚拟机

需要事先自己编译 qemu-system-arm 可执行文件；

1，编译创建ARM 虚拟机

#!/usr/bin/bash sudo lssudo apt-get install gcc-arm-linux-gnueabi#wget https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.10.tar.gztar zxf linux-kernel-v5.10.tar.gz cd linux-5.10/make CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm vexpress_defconfigmake CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm -jcd ../wget https://ftp.denx.de/pub/u-boot/u-boot-2020.10.tar.bz2tar xf u-boot-2020.10.tar.bz2 cd u-boot-2020.10/make vexpress_ca9x4_defconfigmake CROSS_COMPILE=arm-linux-gnueabi- allcd ../wget https://busybox.net/downloads/busybox-1.36.0.tar.bz2tar xf busybox-1.36.0.tar.bz2 cd busybox-1.36.0/make defconfigmake CROSS_COMPILE=arm-linux-gnueabi-make install CROSS_COMPILE=arm-linux-gnueabi-cd ../mkdir -p rootfs/{dev,etc/init.d,lib,proc,sys,root,home}sudo cp busybox-1.36.0/_install/* -r rootfs/sudo cp -P /usr/arm-linux-gnueabi/lib/* rootfs/lib/sudo mknod rootfs/dev/tty1 c 4 1 && sudo mknod rootfs/dev/tty2 c 4 2 && sudo mknod rootfs/dev/tty3 c 4 3 && sudo mknod rootfs/dev/tty4 c 4 4dd if=/dev/zero of=a9rootfs.ext3 bs=1M count=1024mkfs.ext3 a9rootfs.ext3sudo mkdir tmpfs && sudo mount -t ext3 a9rootfs.ext3 tmpfs/ -o loop && sudo cp -r rootfs/*  tmpfs/ && sudo umount tmpfs/home/hipper/ex_systemc_qemu/qemu-bin-v9-arm/bin/qemu-system-arm -M vexpress-a9 -m 512M -kernel ./linux-5.10/arch/arm/boot/zImage -dtb    ./linux-5.10/arch/arm/boot/dts/vexpress-v2p-ca9.dtb -nographic -append "root=/dev/mmcblk0  console=ttyAMA0" -sd a9rootfs.ext3

启动后的虚拟机：

2，编译新的可执行文件

vim ../ex/hello.c

#include <stdio.h>int main()
{printf("Hello Test Kernel ll\n");return 0;}

3，在虚拟机中添加新的可执行文件

cp ../ex/hello busybox-1.36.0/_install/bin/

然后执行 update_exe_arm.sh：

rm -rf a9rootfs.ext3sudo rm rootfs/* -rfmkdir -p rootfs/{dev,etc/init.d,lib,proc,sys,root,home}sudo cp busybox-1.36.0/_install/* -r rootfs/sudo cp -P /usr/arm-linux-gnueabi/lib/* rootfs/lib/sudo mknod rootfs/dev/tty1 c 4 1 && sudo mknod rootfs/dev/tty2 c 4 2 && sudo mknod rootfs/dev/tty3 c 4 3 && sudo mknod rootfs/dev/tty4 c 4 4dd if=/dev/zero of=a9rootfs.ext3 bs=1M count=1024mkfs.ext3 a9rootfs.ext3rm -rf tmpfs/sudo mkdir tmpfs && sudo mount -t ext3 a9rootfs.ext3 tmpfs/ -o loop && sudo cp -r rootfs/*  tmpfs/ && sudo umount tmpfs/home/hipper/ex_systemc_qemu/qemu-bin-v9-arm/bin/qemu-system-arm -M vexpress-a9 -m 512M -kernel ./linux-5.10/arch/arm/boot/zImage -dtb    ./linux-5.10/arch/arm/boot/dts/vexpress-v2p-ca9.dtb -nographic -append "root=/dev/mmcblk0  console=ttyAMA0" -sd a9rootfs.ext3

虚拟机中执行hello；
