需求

windows power shell 运行.ps1脚本启动qemu模拟器加载openharmony镜像。

一、准备工作

1.windows安装qemu：qemu-w64-setup-20221230.exe。
2.管理员启动power shell：win + x。
在这里插入图片描述
3.新建文本文档，扩展名改为.ps1。
4.确保命令行运行qemu命令加载镜像正常启动。
power shell 直接运行命令：

启动命令如下：

C:/program/qemu/qemu-system-riscv64.exe -machine virt -m 4096 -smp 4 -drive if=none,file=updater.img,format=raw,id=updater,index=3 -device virtio-blk-device,drive=updater -drive if=none,file=./system.img,format=raw,id=system,index=2 -device virtio-blk-device,drive=system -drive if=none,file=./vendor.img,format=raw,id=vendor,index=1 -device virtio-blk-device,drive=vendor -drive if=none,file=./userdata.img,format=raw,id=userdata,index=0 -device virtio-blk-device,drive=userdata -append “ip=dhcp loglevel=7 console=ttyS0,115200 init=init root=/dev/ram0 rw rootwait ohos.boot.hardware=visionfive default_boot_device=10007000.virtio_mmio sn=8823456789 ohos.required_mount.system=/dev/block/vdb@/usr@ext4@ro,barrier=1@wait,required ohos.required_mount.vendor=/dev/block/vdc@/vendor@ext4@ro,barrier=1@wait,required ohos.required_mount.data=/dev/block/vdd@/data@ext4@nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc@wait,reservedsize=104857600” -kernel ./Image -initrd ./ramdisk.img -nographic -vga none -device virtio-gpu-pci,xres=320,yres=640,max_outputs=1,addr=08.0 -vnc :20 -device virtio-mouse-pci -device virtio-keyboard-pci -k en-us -display sdl,gl=off

所需镜像文件如下：（忽略.bat和.ps1,镜像文件在linux系统中编译openharmony项目代码成功后的out子目录获取）

运行结果展示：

5.进行终端配置
power shell 执行命令：Set-ExecutionPolicy AllSigned

二、代码编写

#.\qemu_make_run_riscv64.ps1 -updater updater.img -system ./system.img -vendor ./vendor.img -userdata ./userdata.img -kernel ./Image -initrd ./ramdisk.img -qemupath C:/Users/msys64/bn/ -msys2path C:/msys64/

    $userdata  = $(throw "userdata image is required. eg:./userdata.img"),
    $kernel    = $(throw "kernel is required. eg:./Image"),

    $qemupath  = $(),
    $msys2path = $()
)


if($qemupath -eq $null)

    if($exeFileExists)

        $cmd = $exeFilePath
    }
    else
    {
        echo "'$exeFilePath' file not exists, please check."
        Exit
    }
}

$cmd = $cmd + $cmdbody

if($msys2path -eq $null)

    if($cmdFileExists)
    {
        $cmdhead = "C:/msys64/msys2_shell.cmd -defterm -here -no-start -mingw64 -shell bash -c `"$cmd`""
    }
    else
    {
        echo "default C:/msys64/msys2_shell.cmd file not exists, please use -msys2path to certain the 'msys2_shell.cmd' file path."

        echo "$cmdFilePath not exists, please check."

}

#$cmdhead
#$cmd | cmd
$cmdhead | powershell

1.脚本运行方式：powershell 直接执行

.\qemu_run_riscv64.ps1 -updater updater.img -system ./system.img
-vendor ./vendor.img -userdata ./userdata.img -kernel ./Image -initrd ./ramdisk.img -qemupath C:/Users/msys64/bn/ -msys2path C:/msys64/

即可。
2.param()为运行脚本命令需要传入的参数，若没有参数则提示报错。
3.由于运行qumu的命令过长，分行展示更加清晰，所以按字符串的形式以“+”进行拼接。
但需要注意的是不能随意增加空格，否则会导致命令运行不起来，比如：
