ubuntu linux下建立stm32开发环境: GCC安装以及工程Makefile建立

         之前在e络盟的意法半导体掏了一个STM32开发板挺好的,却不想在window下开发,也不想用那么占内存的IAR MDK等软件,所以决定在ubuntu下建立该开发环境,像之前avr linux一样,找了下资料,国内有人做过,但都没有很详尽的教程,所以花了三四天才完成.其实原理很简单,就是安装适用与STM32的GCC,以及建立该工程,主要是Makefile加上STM32的官方库.

环境:

              ubuntu 13.10

              stm32f103zet6

 一  STM 32 GCC 安装

        stm32 属于arm cortex-m系列thumb指令集,所以给arm用的arm-none-eabi就可以了,首先是下载

        下载地址:

               https://launchpad.net/gcc-arm-embedded/+download

        下载其中的gcc-arm-none-eabi-version-linux.tar.bz2

         解压到你知道的目录会产生 gcc-arm-none-eabi的文件夹

        把该编译器添加到你的环境中:

       

sudo gedit  ~/.bashrc

       在最后一行添加:

export PATH=$PATH:/your_stm_gcc_dir/gcc-arm-none-eabi-4_8-2013q4/bin

       因为我之前有添加过树莓派的编译器了,所以实际上是这样的:

export PATH=$PATH:/your_pi_gcc_dir/tools-master/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/:/your_stm_gcc_dir/gcc-arm-none-eabi-4_8-2013q4/bin

         两个编译器环境中间用冒号隔开;

      注销后测试:

arm-none-eabi-gcc -v

      可以查看到该编译器的版本,就表示可以了.

二  工程环境的建立

       新建个工程文件夹,及其目录

mkdir stm_projectcd stm_projectmkdir libsmkdir srcmkdir inc

     下载,安装官方库:

      stm32的寄存器不像51 avr等单片机,那么少,自己写写库,背背寄存器就可以了,所以ST公司提供了他们官方的库,为了避免重复造轮子,就直接采用他们的库,库版本为STM32_USB-FS-Device_Lib_V4.0.0,这个库多了usb支持,下载的话到st官网搜索stm32f10x就有了.

       下载链接:

             stsw-stm32121.zip 

       解压,把解压好的文件夹复制到刚才新建的libs里面.

       在工程根目录下新建Makefile.common文件,这个为通用makefile

# 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 tshowTOP=$(shell readlink -f "$(dir $(lastword $(MAKEFILE_LIST)))")PROGRAM=mainLIBDIR=$(TOP)/libs#Adust the following line to the library in use#=========add by embbnux  根据你的库不同,调整这个地方的库目录地址====================# STMLIB=$(LIBDIR)/STM32_USB-FS-Device_Lib_V4.0.0/Libraries#=========add by embbnux  根据你的stm32芯片型号容量不同,修改这个地方的TypeOfMCU=======##Adjust TypeOfMCU in use, see CMSIS file "stm32f10x.h"#STM32F103RBT (128KB FLASH, 20KB RAM) --> STM32F10X_MD#TypeOfMCU=STM32F10X_MD#STM32F103RET (512KB FLASH, 64KB RAM) --> STM32F10X_HD#STM32F103ZET (512KB FLASH, 64KB RAM) --> STM32F10X_HD#============================================================================#TypeOfMCU=STM32F10X_HD#============================================================================#TC=arm-none-eabiCC=$(TC)-gccLD=$(TC)-ld -vOBJCOPY=$(TC)-objcopyAR=$(TC)-arGDB=$(TC)-gdbINCLUDE=-I$(TOP)/incINCLUDE+=-I$(STMLIB)/CMSIS/IncludeINCLUDE+=-I$(STMLIB)/CMSIS/Device/ST/STM32F10x/IncludeINCLUDE+=-I$(STMLIB)/CMSIS/Device/ST/STM32F10x/Source/TemplatesINCLUDE+=-I$(STMLIB)/STM32F10x_StdPeriph_Driver/incINCLUDE+=-I$(STMLIB)/STM32_USB-FS-Device_Driver/incCOMMONFLAGS=-g -mcpu=cortex-m3 -mthumbCOMMONFLAGSlib=$(COMMONFLAGS)#Commands for general Makefile and src Makefileifeq ($(OptSRC),0)    COMMONFLAGS+=-O0    InfoTextSrc=src (no optimize, -O0)else ifeq ($(OptSRC),1)    COMMONFLAGS+=-O1    InfoTextSrc=src (optimize time+ size+, -O1)else ifeq ($(OptSRC),2)    COMMONFLAGS+=-O2    InfoTextSrc=src (optimize time++ size+, -O2)else ifeq ($(OptSRC),s)    COMMONFLAGS+=-Os    InfoTextSrc=src (optimize size++, -Os)else    COMMONFLAGS+=-O3    InfoTextSrc=src (full optimize, -O3)endifCFLAGS+=$(COMMONFLAGS) -Wall -Werror $(INCLUDE)CFLAGS+=-D $(TypeOfMCU)CFLAGS+=-D VECT_TAB_FLASH#Commands for libs Makefileifeq ($(OptLIB),0)    COMMONFLAGSlib+=-O0    InfoTextLib=libs (no optimize, -O0)else ifeq ($(OptLIB),1)    COMMONFLAGSlib+=-O1    InfoTextLib=libs (optimize time+ size+, -O1)else ifeq ($(OptLIB),2)    COMMONFLAGSlib+=-O2    InfoTextLib=libs (optimize time++ size+, -O2)else ifeq ($(OptLIB),s)    COMMONFLAGSlib+=-Os    InfoTextLib=libs (optimize size++, -Os)else    COMMONFLAGSlib+=-O3    InfoTextLib=libs (full optimize, -O3)endifCFLAGSlib+=$(COMMONFLAGSlib) -Wall -Werror $(INCLUDE)CFLAGSlib+=-D $(TypeOfMCU)CFLAGSlib+=-D VECT_TAB_FLASH

      编译库文件:

      进入libs文件夹,新建Makefile:

        

# libs Makefileinclude ../Makefile.commonLIBS+=libstm32.aCFLAGSlib+=-call: libslibs: $(LIBS)libstm32.a:@echo -n "Building $@ ..."@cd $(STMLIB)/CMSIS/Device/ST/STM32F10x/Source/Templates && \$(CC) $(CFLAGSlib) \system_stm32f10x.c@cd $(STMLIB)/STM32F10x_StdPeriph_Driver/src && \$(CC) $(CFLAGSlib) \-D"assert_param(expr)=((void)0)" \-I../../CMSIS/Include \-I../../CMSIS/Device/ST/STM32F10x/Include \-I../inc \*.c#@cd $(STMLIB)/STM32_USB-FS-Device_Driver/src && \#$(CC) $(CFLAGSlib) \#-D"assert_param(expr)=((void)0)" \#-I../../CMSIS/Include \#-I../../CMSIS/Device/ST/STM32F10x/Include \#-I../inc \#*.c@$(AR) cr $(LIBDIR)/$@ \$(STMLIB)/CMSIS/Device/ST/STM32F10x/Source/Templates/system_stm32f10x.o \$(STMLIB)/STM32F10x_StdPeriph_Driver/src/*.o \#$(STMLIB)/STM32_USB-FS-Device_Driver/src/*.o@echo "done.".PHONY: libs clean tshowclean:rm -f $(STMLIB)/CMSIS/Device/ST/STM32F10x/Source/Templates/system_stm32f10x.orm -f $(STMLIB)/STM32F10x_StdPeriph_Driver/src/*.orm -f $(STMLIB)/STM32_USB-FS-Device_Driver/src/*.orm -f $(LIBS)tshow:@echo "######################################################################################################"@echo "################# optimize settings: $(InfoTextLib), $(InfoTextSrc)"@echo "######################################################################################################"

编译该库:

make cleanmake

就会在lib目录下生成libstm32.a,这个就是编译好的静态库了.

     建立工程编译ld文件

     这个ld文件,为在编译时告诉编译器把代码放到什么地址,根据芯片的内存以及flash容量不同有所调整

      在工程根目录下新建linker.ld文件

      代码较长,请到我的资源里面下载,或者查看参考pdf里面的:

            http://download.csdn.net/detail/canyue102/6778837

      这里说明需要修改的地方,根据芯片型号不同,选择相应的RAM FLASH大小

    

MEMORY {/*Adust LENGTH to RAMsize of target MCU:*//*STM32F103RBT --> 20K*//*RAM (RWX) : ORIGIN = 0x20000000 , LENGTH = 20K*//*STM32F103RET --> 64K*//*STM32F103ZET --> 64K*/RAM (RWX) : ORIGIN = 0x20000000 , LENGTH = 64KEXTSRAM (RWX) : ORIGIN = 0x68000000 , LENGTH = 0/*Adust LENGTH to (FLASHsize - FeePROMsize) of target MCU:*//*STM32F103RBT --> 126K*/FLASH (RX) : ORIGIN = 0x08000000 , LENGTH = 126K/*STM32F103RET --> 508K*//*FLASH (RX) : ORIGIN = 0x08000000 , LENGTH = 508K*//*STM32F103ZET --> 508K*/FLASH (RX) : ORIGIN = 0x08000000 , LENGTH = 508K/*Adust ORIGIN to (0x08000000 + (FLASHsize-FeePROMsize)) of target MCU*//*and adust LENGTH to FeePROMsize allocated:*//*STM32F103RBT --> 0x08000000+126K, 2K*/EEMUL (RWX) : ORIGIN = 0x08000000+126K, LENGTH = 2K/*STM32F103RET --> 0x08000000+508K, 4K*//*EEMUL (RWX) : ORIGIN = 0x08000000+508K, LENGTH = 4K*/}

        在工程根目录下新建Makefile文件:

 

# general Makefileinclude Makefile.commonLDFLAGS=$(COMMONFLAGS) -fno-exceptions -ffunction-sections -fdata-sections -L$(LIBDIR) -nostartfiles -Wl,--gc-sections,-Tlinker.ldLDLIBS+=-lmLDLIBS+=-lstm32STARTUP=startup.call: libs src$(CC) -o $(PROGRAM).elf $(LDFLAGS) \-Wl,--whole-archive \src/app.a \-Wl,--no-whole-archive \$(LDLIBS)$(OBJCOPY) -O ihex $(PROGRAM).elf $(PROGRAM).hex$(OBJCOPY) -O binary $(PROGRAM).elf $(PROGRAM).bin#Extract info contained in ELF to readable text-files:arm-none-eabi-readelf -a $(PROGRAM).elf > $(PROGRAM).info_elfarm-none-eabi-size -d -B -t $(PROGRAM).elf > $(PROGRAM).info_sizearm-none-eabi-objdump -S $(PROGRAM).elf > $(PROGRAM).info_codearm-none-eabi-nm -t d -S --size-sort -s $(PROGRAM).elf > $(PROGRAM).info_symbol.PHONY: libs src clean tshowlibs:$(MAKE) -C libs $@src:$(MAKE) -C src $@clean:$(MAKE) -C src $@$(MAKE) -C libs $@rm -f $(PROGRAM).elf $(PROGRAM).hex $(PROGRAM).bin $(PROGRAM).info_elf $(PROGRAM).info_sizerm -f $(PROGRAM).info_coderm -f $(PROGRAM).info_symboltshow:@echo "######################################################################################################"@echo "################# optimize settings: $(InfoTextLib), $(InfoTextSrc)"@echo "######################################################################################################"

        差不多就好了,在src里面添加测试源码

         主要是startup.c 以及main.c,这里就不在说明了,可以查看该pdf或者到我的资源下载

                  http://download.csdn.net/detail/canyue102/6778885

         然后进入工程主目录,下make就好了.

 

make cleanmake OptLIB=0 OptSRC=0 all tshow

          然后,就完成了,关于ubuntu下烧录程序到stm32下,请见下一篇博客
