On StlinkV2, the original ST Bootloader can also be used with
- Compile firmware with "make PROBE_HOST=stlink ST_BOOTLOADER=1"
- Upload firmware with stlink-tool from [stlink-tool](https://github.com/jeanthom/stlink-tool.git).
Before upload, replug the stlink to enter the bootloader.
- After each stlink replug, use call "stlink-tool" without arguments
to enter BMP
Drawback: After each USB replug, DFU needs to be left explicit!
On Linux, add someting like :
`> cat /etc/udev/rules.d/98-stlink.rules`
`SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3748", ACTION=="add", RUN+="<path-to>/stlink-tool"`
for automatic switch to BMP on replug. However this defeats reflashing further
BMP reflash as long as this rule is active.

If there is a 6-pin connector, connect an external target after removing
the 2 jumper shortening the 4-pin connector like this:
1: VCC sense, used only for measurement
2: SWCLK
3: GND
4: SWDIO
5: nSRST (pulled high by on board target. Will reset with on board target
