stm32f4 discovery보드를 Ubuntu linux에서 시작하기

 

참고

구입해놓고 먼지가 잔뜩 쌓여있던 cortex 보드를 개봉했다.

그리고 gcc환경에서 컴파일하고 보드로 올리는 방법들을 찾아봤다.

 

 

ToolChain 설치

$ sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded

$ sudo apt-get update

$ sudo apt-get install gcc-arm-none-eabi

 

webnautes@virtual-machine:~$ arm-none-eabi-gcc --version

보드 펌웨어 패키지 및 예제 다운로드

http://www.st.com/web/en/catalog/tools/PF257904 에서 보드 펌웨어 패키지 다운로드

$ unzip stsw-stm32068.zip

$ sudo mv STM32F4-Discovery_FW_V1.1.0/ /opt/

 

예제코드 위치

$ ls /opt/STM32F4-Discovery_FW_V1.1.0/Project/Peripheral_Examples/

Stlink 유틸리티 설치

$ git clone https://github.com/texane/stlink.git

$ cd stlink

$ sudo apt-get install autoconf

$ ./autogen.sh

$ ./configure

$ make

$ sudo make install

 

샘플 코드 동작 시켜보기

$ git clone https://github.com/Malkavian/tuts.git

$ cd tuts/stm/blinky

$ ls -l

Makefile 에서 아래 부분을 보드 펌웨어 복사해둔 위치로 수정

STM_DIR=/opt/STM32F4-Discovery_FW_V1.1.0

 

Makefile에서 툴체인 설정 부분도 아래처럼 수정

# The tool we use

CC = arm-none-eabi-gcc

OBJCOPY = arm-none-eabi-objcopy

GDB = arm-none-eabi-gdb

 

컴파일을 해보면 잘됨.

$ make

arm-none-eabi-objcopy -O binary blinky.elf blinky.bin

 

보드에 올리기 위해서 컴퓨터랑 USB 케이블을 이용하여 연결하고 다음 명령을 실행

$ sudo make flash

sudo: unable to resolve host virtual-machine

st-flash write blinky.bin 0x8000000

소스코드를 읽어보고 PD12~PD15사이에 LED를 연결해보니 깜빡거리는 것을 확인해볼 수 있음.
