## 搭建GD32F405基础工程 
###  创建裸机工程
#### [一]准备工作
#### 1.1 创建文件夹 GD32F405_RTT 并创建子文件目录
![工程目录.png](https://oss-club.rt-thread.org/uploads/20210909/11ac747d14080c0bc9802f0606f82dff.png)

文件目录释义:

Application ---- 应用文件
    Board       ---- 版级相关文件
    Driver      ---- 驱动程序
    Firmware    ---- 生成固件
    Library     ---- 固件库
    Project     ---- 工程文件
    System      ---- rtt-thread源代码

#### 1.2 添加固件库文件到Library
![添加固件库文件.png](https://oss-club.rt-thread.org/uploads/20210909/377957016b0a958ce678839257adfdeb.png)

#### 1.3 添加it.c systick.c到Board
![系统中断和滴答定时.png](https://oss-club.rt-thread.org/uploads/20210909/9fe731c14f7e5c31f4f8f4c147142534.png)

#### 1.4 添加main.c 到Application

#### [二]创建工程
#### 2.1 新建工程 并选型为GD32F405VG 创建工程目录
![选型.png](https://oss-club.rt-thread.org/uploads/20210909/856d881fcda6d723a06f0a65e2225506.png)

#### 2.8 添加测试代码 在main.c中添加跑马灯测试程序
```

## 添加RTT源码(完整版)
### [一]准备工作
#### 1.1 准备一个dist 这里用的是GD32F450Z-EVAL的bsp 按图放好文件即可
![rtt.png](https://oss-club.rt-thread.org/uploads/20210909/f9d9bb83e9550e2e849e1c37c1555b41.png.webp)

把startup_gd32f4xx.s 放在 board文件夹下
![startup_gd32f4xx.png](https://oss-club.rt-thread.org/uploads/20210909/168f572a2904ad07e9d0fb4fb8c947fe.png.webp)

### [二]工程配置
#### 2.1 删除源startup_gd32405.s 增加startup_gd32f4xx.s
![s文件配置.png](https://oss-club.rt-thread.org/uploads/20210909/208d9aa5517fe9f399ed67a5de8fa8ff.png)

#### 2.2 添加源文件 src 文件夹下所有文件 不需要kconfig
![rtt-src-1.png](https://oss-club.rt-thread.org/uploads/20210909/59c8f671e9d151f9202a8a16622c71a5.png)

#### 2.3 新建工程目录 CPU  --> 添加libcpu 中的文件 
![lib-cpu-1.png](https://oss-club.rt-thread.org/uploads/20210909/4303b39d1c4707a35f1150f200eba6d9.png)
