STLink
SWD is a program und debug protocoll for ARM processors.
Every STM discovery board comes with a ST-LinkV2 on board (except STM32VL comes with ST-LinkV1).
Every dicovery board from STM comes wih a ST-LinkV2, except STM32VL (ST-LinkV1).

Install Software
For Ubuntu/Debian.
st-flash and st-util are needed Tools from texane
Download and compile
cd git clone git://github.com/texane/stlink.git stlink sudo mv stlink /opt cd stlink ./autogen.sh ./configure make
Set enviroment variables
exportline="PATH=$PATH:/opt/stlink" if grep -Fxq "$exportline" ~/.profile; then echo nothing to do ; else echo $exportline >> ~/.profile; fi source ~/.profile
Add udev rules (replace user with your username)
sudo cp /opt/stlink/49-stlinkv*.rules /etc/udev/rules.d sudo udevadm control --reload-rules
ST-LinkV1 requires a bit different treatment, read the Readme.txt
Airframe.xml setup
Connect the ST-Link to the MCU. If a complete STM32F-Discovery board is used, CN3 jumpers need to be set. To program a external MCU, remove CN3 jumpers and connect the external MCU with the SWD header.
To use STLink via SWD
Set FLASH_MODE=STLINK
Update the ST-Link to blackmagic probe
The STM32F103 (STLink MCU) can be flashed with the blackmagic's firware.
This is irveversable !
