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.

博主最近在电脑上自建了博客，以后会更多的用那个了，欢迎关注访问，里面也有很多有用资源：

          

        http://www.embbnux.com/

      

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_project
cd stm_project
mkdir libs
mkdir src
mkdir 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 tshow

TOP=$(shell readlink -f "$(dir $(lastword $(MAKEFILE_LIST)))")
PROGRAM=main
LIBDIR=$(TOP)/libs

      编译库文件:

      进入libs文件夹,新建Makefile:

        

# libs Makefile
include ../Makefile.common
LIBS+=libstm32.a
CFLAGSlib+=-c

all: libs

libs: $(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 tshow

clean:
	rm -f $(STMLIB)/CMSIS/Device/ST/STM32F10x/Source/Templates/system_stm32f10x.o
	rm -f $(STMLIB)/STM32F10x_StdPeriph_Driver/src/*.o
	rm -f $(STMLIB)/STM32_USB-FS-Device_Driver/src/*.o
	rm -f $(LIBS)
tshow:
	@echo "######################################################################################################"
	@echo "################# optimize settings: $(InfoTextLib), $(InfoTextSrc)"
	@echo "######################################################################################################"

编译该库:

make clean
make

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 = 64K
	EXTSRAM (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 Makefile

include Makefile.common
LDFLAGS=$(COMMONFLAGS) -fno-exceptions -ffunction-sections -fdata-sections -L$(LIBDIR) -nostartfiles -Wl,--gc-sections,-Tlinker.ld

LDLIBS+=-lm
LDLIBS+=-lstm32

STARTUP=startup.c

all: 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_elf
	arm-none-eabi-size -d -B -t $(PROGRAM).elf > $(PROGRAM).info_size
	arm-none-eabi-objdump -S $(PROGRAM).elf > $(PROGRAM).info_code
	arm-none-eabi-nm -t d -S --size-sort -s $(PROGRAM).elf > $(PROGRAM).info_symbol

.PHONY: libs src clean tshow

libs:
	$(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_size
	rm -f $(PROGRAM).info_code
	rm -f $(PROGRAM).info_symbol
tshow:
		@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 clean
make 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
