STM32 Linux

Debugger OpenOCD

  • [http://openocd.org/doc/html/index.html Help page.]
  • Use either ST-LINK or OpenOCD, can work with ST-LINK2
  • For example OpenOCD, run command as follow to install

    install openocs: sudo apt-get install openocd

    setup up for usbdevice: sudo vi /etc/udev/rules.d/99-stlink.rules

    add conent: ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3748", MODE="0666"

    reload setup: sudo udevadm control –reload-rules

    open board: openocd -f /usr/share/openocd/scripts/board/stm32f3discovery.cfg

    or use: /usr/share/openocd/scripts# openocd -f interface/stlink-v2.cfg -f target/stm32f1x_stlink.cfg

  • If well connected, result will show:

  • Run another terminal and telnet to the board: telnet localhost 4444
  • halt it into debug mode: reset halt or: reset init
  • Reflash bin into board: flash write_image erase maple_mini_boot.bin 0x08000000 flash write_image erase /media/sf_VM_XP_share/LED.hex
  • Finall reset it to start up again: reset run

Toolchain

  • Install: sudo apt-get install gcc-arm-none-eabi

Firmware libopencm3 and test code

  • git clone the firmware and try stm32f103 demo blink code, the firmware works like arduino git clone https://github.com/libopencm3/libopencm3-examples.git cd libopencm3-examples git submodule init // git submodule update make
  • enter into board folder like: cd libopencm3-examples/examples/stm32/f3/stm32f3-discovery/miniblink
  • for STM32F1x board, enter into /libopencm3-examples/examples/stm32/f1/stm32-h103//miniblink/
  • firmware support openocd, can run make flash directory
  • Or manually telnet to openocd: telnet localhost 4444 reset halt flash write_image erase miniblink.elf reset
