Version # Release Date Release Notes
v1.00 (current) 04/2014 Initial release
v0.00 02/2014 Prototype

Detailed Features

Fully compatible with the Black Magic Probe, the features are identical:
(following is a copy of Black Magic Probe's webpage)

  • Aimed at ARM Cortex based microcontrollers.
  • Allows direct connection to the targeted processors JTAG interface. Alternatively, you may use the ARM Serial Wire Debug protocol as well.
  • Full debugging functionality is provided. This includes: watchpoints, flash memory breakpoints, memory and register examination, flash memory programming, etc.
  • Multiple targets on a single JTAG scan chain is supported.
  • Interface to the host computer is a standard USB CDC ACM device (a virtual serial port), which does not require special drivers on Linux.
  • 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 upgrades (as updates become available).
  • Windows, Linux and Mac environments supported.

This board allows you to:

  • Load your application into the target processor Flash memory or RAM.
  • Single step through your program.
  • Run your program in real-time with halt on demand.
  • Examine and modify CPU registers and memory.
  • Obtain a call stack backtrace.
  • Set up to 6 hardware assisted breakpoints.
  • Set up to 4 hardware assisted read, write or access watchpoints.
  • Set unlimited software breakpoints when executing your application from RAM.

Getting, compiling flashing firmware

Since the criquet probe is an accurate copy of bmack magic probe, the black magic probe documentation applies.

Here is an abstract of the software installation.

° You will need the same cross compiler as used by paparazzi, so, if you allready use paparazzi, this point is already done.

° get and compile source : git clone https://github.com/gsmcmullin/blackmagic.git

cd blackmagic ; git submodule init ; git submodule update ; make

at this point, the bootloader and the debugging firmware are compiled.

Well will use the stlink part of a stm32 discovery (all stm32 discovery will be good to do the job) to program the bootloader :

° remove the two programming jumper on the discovery card (refer to the discovery card stm32 documentation)

° wire discovery SWD connector to criquet probe (cf upper shematic)

° load the bootloader : st-flash write ./src/blackmagic_dfu.bin 0x08000000
