# 一、需要用到的工具和安装包
1. vscode :  https://code.visualstudio.com/#
2. RT-Thread env工具:  https://www.rt-thread.org/download.html
3. RT-Thread内核:  https://github.com/RT-Thread/rt-thread.git

# 二、实现步骤
## a) 下载第一点提到的工具和安装包
## b) vscode的准备工作：
1. 下载并安装vscode
2. 安装必要的组件：

3. 到rt-thread关于mcxn947的工程目录并通过vscode打开
rt-thread\bsp\nxp\mcx\mcxn\frdm-mcxn947  -> ![screenshot_image.png](https://oss-club.rt-thread.org/uploads/20240320/3834c539959ce5e15561a4e99c84e5fb.png)
4. 在上方的命令执行行输入> Tasks: Configure Task 生成.vscode/tasks.json, 并编辑

```json
{
	// See https://go.microsoft.com/fwlink/?LinkId=733558
	// for the documentation about the tasks.json format
	"version": "2.0.0",
	"tasks": [
		{
			"label": "make",
			"type": "shell",
			"command": "H:/mcxn947/env-windows-1.5.0/tools/bin/make.exe",
			"args": [
				"-j"
			]
		},
		{
			"label": "make clean",
			"type": "shell",
			"command": "H:/mcxn947/env-windows-1.5.0/tools/bin/make.exe",
			"args": [
				"clean"
			]
		}
	]
}
```
*ps：command用到的是env工具里的make工具，具体路径请按实际修改。*

## c) RT-Thread env工具的准备工作
1. 进入env工具包的目录
2. 双击运行env.exe
3. 通过cd命令切换到\rt-thread\bsp\nxp\mcx\mcxn\frdm-mcxn947\目录
	比如：cd ..\rt-thread\bsp\nxp\mcx\mcxn\frdm-mcxn947\
4. 在该目录下执行**scons --target=makefile**

	在frdm-mcxn947\目录下便会生成Makefile、config.mk、src.mk三个文件
5. 修改文件config.mk
在DEFINES的结尾添加一项 ![screenshot_image.png](https://oss-club.rt-thread.org/uploads/20240320/cfba34a91afe507c9e8ccd0b83d78209.png)
6. 修改文件rt-thread\tools\rtthread.mk
![screenshot_image.png](https://oss-club.rt-thread.org/uploads/20240320/a87194a8ed35beafc8d9b5b0c4eec888.png.webp)

*删除以上两项。此处因为修改了rtthread.mk，可能会影响到其他工程编译，请留意。*

## d) 编译过程
1. 打开工程目录 
rt-thread\bsp\nxp\mcx\mcxn\frdm-mcxn947  ->  ![screenshot_image.png](https://oss-club.rt-thread.org/uploads/20240320/3834c539959ce5e15561a4e99c84e5fb.png)
2. 在vscode上方的命令执行行输入> Tasks: Run Task 选择 make clean -> Continue without scanning the task output.
