PC：Ubuntu 18.04.1，开发板：STM32F103C8T6

version

使用交叉编译器：gcc-arm-none-eabi

1
apt-get install gcc-arm-none-eabi

安装完成后输入arm-none-eabi- 然后按tab键看到很多文件 说明安装成功了
详细可以看我另两篇博文

下载stm32固件库
www.st.com/zh 下载，并解压（~/stm32/codes/stm_project）

1
2
root@tiger:~/stm32/codes# ls
en.stsw-stm32054.zip

创建目录
libs目录放stm32固件库，src放用户源码，inc放用户头文件

1
2
root@tiger:~/stm32/codes/stm_project# ls
inc  libs  src

创建Makefile.common
在主目录下创建Makefile.common文件，这个是通用Makefile文件

# include Makefile
 
#This file is included in the general Makefile, the libs Makefile and the src Makefile
#Different optimize settings for library and source files can be realized by using arguments
#Compiler optimize settings:
# -O0 no optimize, reduce compilation time and make debugging produce the expected results (default).
# -O1 optimize, reduce code size and execution time, without much increase of compilation time.
# -O2 optimize, reduce code execution time compared to ‘O1’, increase of compilation time.
# -O3 optimize, turns on all optimizations, further increase of compilation time.
# -Os optimize for size, enables all ‘-O2’ optimizations that do not typically increase code size and other code size optimizations.
#Recommended optimize settings for release version: -O3
#Recommended optimize settings for debug version: -O0
#Valid parameters :
# OptLIB=0 --> optimize library files using the -O0 setting
# OptLIB=1 --> optimize library files using the -O1 setting
# OptLIB=2 --> optimize library files using the -O2 setting
# OptLIB=3 --> optimize library files using the -O3 setting
# OptLIB=s --> optimize library files using the -Os setting
# OptSRC=0 --> optimize source files using the -O0 setting
# OptSRC=1 --> optimize source files using the -O1 setting
# OptSRC=2 --> optimize source files using the -O2 setting
# OptSRC=3 --> optimize source files using the -O3 setting
# OptSRC=s --> optimize source files using the -Os setting
# all --> build all
# libs --> build libs only
# src --> build src only
# clean --> clean project
# tshow --> show optimize settings
#Example:
# make OptLIB=3 OptSRC=0 all tshow

编译固件库

1.首先编译固件库，将固件库编译成静态库，应用程序可以直接使用.

2.下载startup.c，路径：stm_project/libs/STM32F10x_StdPeriph_Lib_V3.5.0/Libraries/

CMSIS/CM3/DeviceSupport/ST/STM32F10x/startup/arm/

3.编写Makefile文件，路径：stm_project/libs/STM32F10x_StdPeriph_Lib_V3.5.0/Libraries/

STM32F10x_StdPeriph_Driver/src

建立ld文件
项目根目录建立linker.ld文件，根据芯片的内存以及flash容量
下面是文件需要修改的地方
