Build

Unable to cross compile for ARM with Scons because /Fo is added

需要指定构建环境用到的工具 Appendix C. Tools

SConstruct

env = Environment(ENV=os.environ, tools=['gcc', 'g++', 'gnulink', 'ar', 'as'])

依照 Makefile 的内容配置 Environment

Working Directory = firmware

Glob

阮一峰-命令行通配符教程

C_Src_Dirs = [
    'Core/Src',
]

C_Glob_Srcs = []
for _dir in C_Src_Dirs:
    C_Sources += Glob(f'{_dir}/*.c')

使用 Glob 简化多文件编译
