cd ~/git
git clone --recursive https://github.com/texane/stlink
cd stlink
make -j4

Clone and build the firmware for Black Magic Probe, note to use stlink as PROBE_HOST:

cd ~/git
git clone --recursive https://github.com/blacksphere/blackmagic.git
cd blackmagic
cd libopencm3
make -j4 lib
cd ../src
make -j4 PROBE_HOST=stlink

Flash the uBMP:

cp ../../stlink/build/Release/st-flash .
./st-flash erase
./st-flash write blackmagic_dfu.bin 0x8000000
