当要执行编译好的RT-Thread时，在这个bsp目录下已经提供了运行脚本文件：qemu.bat和qemu.sh。可以在bsp目录下运行env，在env中敲入qemu.bat即可直接运行。
|
||||
### 3.1 执行脚本文件说明
|
||||
|
||||
在这个bsp目录下已经提供了下面几个执行脚本文件，具体的说明如下表所示：
|
||||
|
||||
| 执行脚本文件 | 运行平台 | 备注 |
|
||||
| ------ | ---- | :------: |
|
||||
| qemu.bat | Windows | 普通模式启动运行 |
|
||||
| qemu.sh | Linux | 同上 |
|
||||
| qemu-dbg.bat | Windows | 调试模式启动运行 |
|
||||
| qemu-dbg.sh | Linux | 同上 |
|
||||
| qemu-nographic.bat | Windows | 以不带界面的模式启动运行 |
|

| qemu-nographic.sh | Linux | 同上 |

|
||||
当要执行编译好的RT-Thread时，可以在bsp目录下运行env，在env中敲入qemu.bat即可直接运行。
|
||||
|
||||
这个执行脚本默认把串口输出到stdio（即控制台）上，所以直接执行脚本后就可以输出结果了。

|
||||
|
||||
当然你也可以尝试使用其他两个**.bat**文件启动运行。
|
||||
|
||||
#### 3.2.2 退出QEMU运行
|
||||
|
||||
在msh提示输入的状态下，按下 **CTRL+C** ，有以下提示之后，按下 **y** ，即可退出 QEMU 。
|
||||
|
||||
```shell
|
||||
hello rt-thread
|
||||
msh />
|
||||
msh />
|
||||
msh />Terminate batch job (Y/N)? y
|
||||
```
|
||||
|
||||
### 3.3 Linux下执行RT-Thread
|
||||
|
||||
#### 3.3.1 安装QEMU工具包
|
||||
|
||||
在Linux下调试启动与Windows下稍微有点点区别，由于Windows下安装了**env**工具就自带了**qemu-system-arm**，而Linux下默认是没有这个工具的，所以执行执行`./qemu.sh`会报错：
|
||||
|
||||
```shell
|
||||
bsp/qemu-vexpress-a9$ ./qemu-nographic.sh
|
||||
./qemu-nographic.sh: line 5: /usr/bin/qemu-system-arm: No such file or directory
|
||||
```
|
||||
|
||||
这个时候需要在Linux平台安装**qemu-system-arm**工具包，以**Linux Ubuntu**平台为例，使用以下命令即可安装对应的工具包：
|
||||
|
||||
```shell
|
||||
bsp/qemu-vexpress-a9$ sudo apt-get install qemu-system-arm
|
||||

||||

|
||||
The following package was automatically installed and is no longer required:
|
||||
tinyproxy-bin
|
||||
Use 'sudo apt autoremove' to remove it.
|
||||
Suggested packages:
|
||||
vde2
|
||||
The following NEW packages will be installed:
|
||||
qemu-system-arm

||||

||||

|
||||
```
|
||||
|
||||
提示安装成功后，输入查看**qemu-system-arm**版本信息的命令，如果可以看到对应的版本信息，证明它可以正常使用。
|
||||
|
||||
```shell
|
||||
/bsp/qemu-vexpress-a9$ qemu-system-arm --version
|
||||

||||
```
|
||||
|
||||
#### 3.3.2 启动QEMU运行
|
||||
|
||||
由于Linux平台一般都是不带界面的服务器，所以推荐使用`qemu-nographic.sh`脚本来启动运行，参考运行示例如下：
|
||||
|
||||
```shell
|
||||
bsp/qemu-vexpress-a9$ ./qemu-nographic.sh
|
||||
WARNING: Image format was not specified for 'sd.bin' and probing guessed raw.
|
||||
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
|
||||
Specify the 'raw' format explicitly to remove the restrictions.

#### 3.3.3 退出QEMU运行
|
||||
|
||||
Linux下退出QEMU的方式与Windows下有些不一样；在msh提示输入的状态下，按下 **CTRL+A** ，再按下 **X** ，即可退出 QEMU 。
|
