Stlink V2/3 with original STM firmware as Blackmagic Debug Probes
ST-Link V2/3 with original STM firmware as Blackmagic Debug Probes
Recent STM Stlink firmware revision (V3 and V2 >= J32) expose nearly all
functionality that BMP needs. This branch implements blackmagic debug probe
for the STM Stlink as a proof of concept.

Use at your own risk, but report or better fix problems.
Run the resulting blackmagic_stlinkv2 executable to start the gdb server
Compile with "make PROBE_HOST=pc-stlinkv2"
Crosscompling for windows with mingw succeeds.
Run the resulting blackmagic_stlinkv2 executable to start the gdb server.
You can also use on the command line alone, e.g
- "blackmagic_stlinkv2 -t" to scan and display the results of the scan
- "blackmagic_stlinkv2 <file.bin>" to flash <file.bin> at 0x08000000
- "blackmagic_stlinkv2 -h" for more options
Cross-compling for windows with mingw succeeds.
Drawback:
- JTAG does not work for chains with multiple devices.
- STLinkV3 does only work on STM32 devices.
- ST-LINKV3 seem to only work on STM32 devices.
- St-LINKV3 needs connect under reset on more devices than V2
This branch may get forced push. In case of problems:
- git reset --hard master
- git rebase
ToDo:
- Implement an SWO server
