立创天空星GD32开发板开源嵌入式组件移植测试GCC-Makefile-Pyocd工程模板建立

立创开发板开源嵌入式组件移植测试 GCC Makefile Pyocd 工程模板建立

Windows环境搭建参考

参考教程 https://blog.csdn.net/weixin_42328389/article/details/119823834
仓库收集 https://github.com/cjacker

一、本次环境搭建所用的软硬件

1）Windows or Linux (本文以Windows为主，linux基本环境流程差不多，可能需要修改部分Makefile代码)

2）JLink、Daplink、Wch-Link烧录器

3）GNU Arm Embedded Toolchain交叉编译器

4）Mingw-w64 GCC for Windows 64

5）GD32F407VET6 立创开发板

二、软件安装配置

GNU Arm Embedded Toolchain交叉编译器
进入arm开发者官网，往下滑动选择下载解压可用的ZIP压缩包文件
下载链接： Downloads | GNU Arm Embedded Toolchain Downloads – Arm Developer
将下载好的压缩包文件解压在gcc-arm-none-eabi”文件夹中，并记住文件内“bin”文件的路径，后续需添加到系统环境变量Path中。
添加完环境变量后，进行测试，检测是否安装好。
安装Mingw-w64 GCC
点击链接进入到SourceForge官网，往下翻可以找到很多版本的下载链接，选择红色框内型号即可，不同前后缀的具体差异请参考:
MinGW gcc下载链接及sjlj、dwarf、seh异同以及gcc安装_AMDDMA的博客-CSDN博客_seh和sjlj
下载链接：
MinGW-w64 - for 32 and 64 bit Windows - Browse Files at SourceForge.net
同样，将下载好的文件解压到“gcc-arm-none-eabi”文件夹下，记住目录下的“bin”文件路径
进入“bin”文件内找到“mingw32-make”应用程序文件，复制一份并重命名为“make”。这么做有利于在命令行执行make指令，而不是输入mingw32-make。

添加完环境变量后，进行测试，检测是否安装好。

3. 安装PyOCD

pyocd学习教程 https://www.cnblogs.com/halin/p/15169658.html

pip install -i https://pypi.tuna.tsinghua.edu.cn/simpl pyocd

综上所述，基本的软件环境已经配置好。

三、GD32F407-GCC-Template工程配置

Linux环境搭建

安装GNU Arm Embedded Toolchain交叉编译器
进入arm开发者官网，往下滑动选择下载解压可用的ZIP压缩包文件，选择linux版本
也可以直接在linux系统中下载，这里使用的Ubuntu 22.04
```
sudo apt-get install gcc-arm-none-eabi
```
下载完成查看
```
arm-none-eabi-gcc -v
```
修改Makefile
注释GCC_PATH
修改 clean命令

四、工程测试

make 构建工程
make program pyocd
接上串口线，打开串口软件，查看终端输出情况（如果是从MDK-Keil工程移植过来，printf应该是不支持的，因此终端没有输出，需要修改相关代码，后面写修改文件）（图片中的情况是修改之后的效果）

注意修改的部分

uart printf重定向问题

//重定向c库函数printf到串口，重定向后可使用printf函数
// int fputc(int ch, FILE *f)
// {
//     /* 发送一个字节数据到串口 */
//     usart_data_transmit(COM_UART[0], (uint8_t) ch);

//     /* 等待发送完毕 */
//     while (usart_flag_get(COM_UART[0], USART_FLAG_TBE) == RESET);

//     return (ch);
// }

int _write (int fd, char *pBuffer, int size)  
{  
    for (int i = 0; i < size; i++)  
    {  
        usart_data_transmit(COM_UART[0], (uint8_t)pBuffer[i]);
        while(RESET == usart_flag_get(COM_UART[0], USART_FLAG_TBE));     
    }  
    return size;  
}
