Makefile文件的生成和修改

  1. 先使用STM32CubeMX生成Hal库的makefile工程
    • Alt text
  2. 删除大部分文件，保留两个文件
    1. Makefile文件
    2. 链接脚本，文件名可能为：STM32F103C8Tx_FLASH.ld
  3. 下载并解压STM32F10x_StdPeriph_Lib_V3.5.0
  4. 复制STM32F10x_StdPeriph_Lib_V3.5.0到Drivers目录
  5. 修改Makefile文件
修改后的Makefile
# ------------------------------------------------
# Generic Makefile (based on gcc)
#
# ChangeLog :
# 	2024-07-22 - 实现c/c++混合编译、调用openocd实现写入/擦除
#	2017-02-10 - Several enhancements + project update mode
#   2015-07-22 - first version
