STM32 OpenOCD
STM32 Linux
Debugger OpenOCD
- 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
