试了好久，终于成功搭建windows下的GCC开发环境。开发环境如下：
系统：Win11
编译环境：GCC
仿真环境：pyOCD
整个开发环境的搭建，可以参考：https://mp.csdn.net/mp_blog/creation/editor/142444700
gcc开发环境下MCU编程，除了要搭建好开发环境之外，还有三个重要的文件，分别是makefile、.ld文件及.s文件。
在HC32F448提供的DDL demo中，有eclipse工程，里边包含了.ld文件及.s文件，还差了makefile文件。
在此奉献上我调试好的makefile文件，抛砖引玉，让更多人来使用及优化。也希望大神能提出不足及指正。

将此文件放到HC32F448_DDL_Rev1.1.0\projects\ev_hc32f448_lqfp80\examples\adc\adc_awd\GCC目录下，其他工程目录，需要更改相应的内容。
在HC32F448_DDL_Rev1.1.0\projects\ev_hc32f448_lqfp80\examples\adc\adc_awd\GCC目录下右键选择在终端中打开，执行make
编译成功后显示
下载：
观察串口log
可以看到gcc-ARM编译的文件在F448上已经成功执行。
