I ran through the instructions that you provided here -> https://github.com/stm32duino/wiki/wiki/How-to-debug
Sloeber complained about my install path being over 40 chars, so I followed the advice here -> https://github.com/Sloeber/arduino-ecli … issues/705 so I could run eclipse from within a temp M: drive using subst.
I can successfully build and upload code to a bluepill, but when I try debug I have no luck.
OpenOCD.exe starts fine
But I get this output:

Do you use the proper USB cable?
I’m joke
Googling your issue, it seems it could be related on USB port use. Is it an USB 3 port ?
Other question, did you update the stlink firmware ?
St-Link is at latest firmware.
Thanks.
PS, you mean this SCART lead won’t work?
Anyway I also seen that boards connected on USB3 port seems work on a limited mode….
Have a nice debug 
Bit of a learning curve:
* Custom libraries – it doesn’t like them – I managed to frig them in by including a false version number subfolder in the library folder which contained the source
* any typedef’s or constants defined in a .h will cause a compile error if you have that .h explicitly included. Sloeber builds a sloeber.ino.cpp with all the includes and for some reason that leads to double definitions, but not for anything else?? So comment out includes in main project.
* build_opts.h is ignored – had to manually instantiate Serial3
Compiles and uploads though – and the eclipse/sloeber IDE has already helped me spot some goofs, = instead of == etc.

look into #pragma once
Seems not so easy… sorry
About .h, I guess contact Jantje could be fine. (Github issue?)
About build_opt.h, I need to test but think about it I guess it attempt to have it in folder sketch. Get back on this.

Never try with custom library…
Seems not so easy… sorry
I cheated it – and my cheat worked

Cool, thanks.
EDIT – worked a charm, doffs cap.
In Properties window, then “C/C++ Build-> Environnement”, the A.BUILD_OPT.SOURCEPATH is not correct.
It is expand as /build_opt.h
Under Arduino IDE, this check in sketch folder if file exist if not an empty one is created else it is copied by Arduino IDE Stuff to the build directory in sketch folder.
Unfortunately this step is not reproduced with Sloeber that’s why even if A.BUILD_OPT.SOURCEPATH find the file it is not copied.
As a workaround, I’ve set A.BUILD_OPT.SOURCEPATH to be equal to A.BUILD_OPT.PATH
Then in the build dir under Eclipse, in sketch folder I create or update the build_opt.h file.
Then clean the project to force rebuild all. Like this it is ok.
