STM32: Black Magic Probe @ BRO-DBG-LINK-V2-1

通过gdb(arm-none-eabi-gdb) 调试STM32系列MCU, 我们可以通过gdb + OpenOCD + ST-LINK/V2的方式进行在线调试。而Black Magic Proble的出现,使得我们我们可以直接通过gdb + Black Maigc Probe进行在线调试。由于不需要OpenOCD作媒介,进行在线调试会方便很多。

从可以了解到Black Magic Probe除了Native Hardware: Black Magic Probe Mini V2.0 (BMPM2)/Black Magic Probe Mini V1.0(BMPM1)/Black Magic Probe外,还支持FTDI target, ST Link,F4 Discovery,SW Link及Launchpad ICDI。由于BRO-DBG-LINK-V2-1是与ST-LINK兼容的硬件,这使得我们可以在BRO-DBG-LINK-V2-1上运行Black Magic Probe固件。

关于ST Link的支持情况,请看。

  • 关于Black Magic Probe

1. 介绍(

The Black Magic Probe is a modern, in-application debugging tool for embedded microprocessors. It allows you see what is going on ‘inside’ an application running on an embedded microprocessor while it executes. It is able to control and examine the state of the target microprocessor using a JTAG or Serial Wire Debugging (SWD) port and on-chip debug logic provided by the microprocessor. The probe connects to a host computer using a standard USB interface. The user is able to control exactly what happens using the GNU source level debugging software, GDB.

2. 特点(

  • Targets ARM Cortex-M and Cortex-A based microcontrollers.
  • Connects to the target processor using the JTAG or Serial Wire Debug (SWD) interface.
  • Provides full debugging functionality, including: watchpoints, flash memory breakpoints, memory and register examination, flash memory programming, etc.
  • Semihosting / Host IO support
  • Interface to the host computer is a standard USB CDC ACM device (virtual serial port), which does not require special drivers on Linux or OS X.
  • Implements the GDB extended remote debugging protocol for seamless integration with the GNU debugger and other GNU development tools.
  • Implements USB DFU class for easy firmware upgrade as updates become available.
  • Works with Windows, Linux and Mac environments.
  • 代码下载及编译

1. 代码下载

$ git clone

由于代码中包含子模块libopencm3, 还需要如下操作:

$ cd backmagci
$ git submodule init
$ git submodule update


如果执行”git submodule update”更新速度太慢,可以通过如下方法:

$ git clone
$ git submodule update

2. 编译代码

$ make PROBE_HOST=stlink


$ make PROBE_HOST=stlink

- backmagic

- backmagic_dfu

- dfu_upgrade


- bootloader:占用0x2000个字节,存放的是backmagic_dfu文件,用于加载与更新固件。

- app:起始位置为(0x08002000)存放的是backmaigc或者是dfu_upgrade文件,dfu_upgrade固件用于更新bootloader。

  • 固件下载及更新

1. 下载bootloader文件,可通过OpenOCD + ST-LINK/V2-1下载

$ openocd -f interface/stlink-v2-1.cfg -f target/stm32f1x.cfg -c init -c 'reset halt' -c 'flash write_image erase src/blackmagic_dfu.bin 0x08000000 bin' -c 'verify_image src/blackmagic_dfu.bin 0x08000000 bin' -c 'reset run' -c shutdown

2. 下载app文件

$ openocd -f interface/stlink-v2-1.cfg -f target/stm32f1x.cfg -c init -c 'reset halt' -c 'flash write_image erase src/blackmagic.bin 0x08002000 bin' -c 'verify_image src/blackmagic.bin 0x08002000 bin' -c 'reset run' -c shutdown
