极海APM32F411V Tiny开发板评测05——GCC Makefile Pyocd 工程模板建立

极海APM32F411V Tiny开发板评测 GCC Makefile Pyocd 工程模板建立

一、移植前的准备

1. 准备目标硬件（开发板/芯片/模组）

本教程将使用极海APM32F411V Tiny开发板进行示例移植。调试ARM Cortex M核还需要仿真器，如果您的开发板或者芯片模组没有板载仿真器，就需要连接外置的仿真器，如DAPLink之类的。

2.准备编译器环境

1）Windows or Linux (Windows，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

3.Windows环境搭建

GNU Arm Embedded Toolchain交叉编译器安装

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.创建工程，编写Makefile
