Getting, compiling flashing firmware

Since the criquet probe is an accurate copy of black 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 already use paparazzi, this point is already done. This procedure assume that your are using a linux box. For a macosx gear, it will be different, feel free to complete the wiki if you know how to do the job from a mac.

Get and compile source from GitHub: 

git clone https://github.com/gsmcmullin/blackmagic.git
cd blackmagic 
git submodule init 
git submodule update 
make

Flash the bootloader via a STLink (all STM32 Discovery boards provide one onboard) with st-flash onto the criquet MCU:

  1. remove the two programming jumper on the discovery card (refer to the discovery card stm32 documentation)
  2. wire discovery SWD connector to criquet probe (cf upper shematic) (disco-swdio => criquetprobe-rx ; disco-swclk => criquetprobe-tx ; ground connected)
  3. plug discovery on an usb port on your computer
  4. load the bootloader : st-flash write ./src/blackmagic_dfu.bin 0x08000000
  5. unplug the discovery (and don't forget to put back the jumpers if you want to use it again as a discovery board)

Still need one step to have a useful device, see on next chapter how to program black magic gdb client firmware.

Firmware Upgrade

This requires an functional bootloader (see previous chapter).

  1. cd the rootdir of previously downloaded git repository
  2. maintain the small black button of the criquet probe while connecting it to computer via usb.
  3. the red led should be flashing, indicating that the criquet wait for firmware upload
  4. sudo ./scripts/stm32_mem.py src/blackmagic.bin
  5. unplug and replug usb
