### 一、需要用到的工具和安装包
1. Linkserver 1.4.85 installer for Windows （nxp官网）

ps:
vscode和rtthread的下载连接请参阅[《使用VSCode 搭建 RT-Thread 关于 NXP mcxn947 开发环境（一）》](https://club.rt-thread.org/ask/article/1ce86e6e1663f358.html "《使用VSCode 搭建 RT-Thread 关于 NXP mcxn947 开发环境（一）》")

### 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. 安装必要的组件：

2. 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/20240322/3834c539959ce5e15561a4e99c84e5fb.png)
3. 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": [
				"-j1"
			]
		},
		{
			"label": "make clean",
			"type": "shell",
			"command": "H:/mcxn947/env-windows-1.5.0/tools/bin/make.exe",
			"args": [
				"clean"
			]
		},
		{
			"label": "flash",
			"type": "shell",
			"command": "C:/NXP/LinkServer_1.4.85/LinkServer.exe",
			"args": [
				"flash",
				"MCXN947:FRDM-MCXN947",
				"load",
				"./rtthread.elf"
			]
		},
		{
			"label": "erase",
			"type": "shell",
			"command": "C:/NXP/LinkServer_1.4.85/LinkServer.exe",
			"args": [
				"flash",
				"MCXN947:FRDM-MCXN947",
				"erase"
			]
		},
		{
			"label": "start LinkServer",
            "type": "shell",
            "command": "C:/NXP/LinkServer_1.4.85/LinkServer.exe",
            "args": [
				"gdbserver",
				"MCXN947:FRDM-MCXN947"
			]
        },	]
}
```

*ps:*
- *command用到的是env工具里的make工具，具体路径请按实际修改。*
- *请替换LinkServer.exe的路径为用户安装路径。*

4. 修改launch.json文件
```json
{
	// Use IntelliSense to learn about possible attributes.
	// Hover to view descriptions of existing attributes.
	// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
	"version": "0.2.0",
	"configurations": [
		{
			"name": "Cortex Debug",
			"cwd": "${workspaceFolder}",
			"executable": "./rtthread.elf",
			"request": "launch",
			"type": "cortex-debug",
			"runToEntryPoint": "main",
			"servertype": "external",
			"gdbTarget": "localhost:3333",
			"armToolchainPath": "H:/mcxn947/env-windows-1.5.0/tools/gnu_gcc/arm_gcc/mingw/bin/",			
		}
	]
}
```

*ps: *
- 请替换工具链路径为用户实际安装路径。

c) 烧写过程
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/20240322/3834c539959ce5e15561a4e99c84e5fb.png) 
2. 全片擦除：在vscode上方的命令执行行输入> Tasks: Run Task 选择 erase-> Continue without scanning the task output.
3. 程序烧写：在vscode上方的命令执行行输入> Tasks: Run Task 选择 flash-> Continue without scanning the task output.

d) 调试过程
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/20240322/3834c539959ce5e15561a4e99c84e5fb.png)
