After flashing this test, you will not be able to address blue pill using openocd.

To work-around this problem, I switched boot0 jumper, used stm32loader (after pressing reset button) to load alternative binary.

since version 1.2.8 you need to insert vid and pid into the binary by running

make build/gnuk-vidpid.elf

and than flash the resulting gnuk-vidpid.bin binary into your FST-01

Core does not halt, try API V2 halt.
ValueError('Status of core is not halt.', 128)

after a bit of fiddling with cables (it's always cables, right?)

Lovro contributed that if you are getting continous output like this

ST-Link/V2 version info: 2 17 4
Change ST-Link/V2 mode 0002 -> 0001
Core does not halt, try API V2 halt.
ValueError('Status of core is not halt.', 128)

then run this while holding reset active (hold tweezers on both side of C3)
that should hand the uC in a mode that will enable stlinkv2.py script to turn off the flash rom protection and erase the flash while doing that

dpavlin@blue:/blue-zfs/STM32/FST-01/gnuk$ sudo ./tool/stlinkv2.py -s
