The issue happened again and I think I know the reason now.
Yesterday was working on a newly set up project, all working well - including debugging.
Over night the PC was in standby, debugger was still connected and the DAVE project was opened.
Today I brought up the PC, but on the first attempt to flash I got an error message in DAVE that the jLink interface was not found.
So I unplugged/plugged the board again (its a xmc2go board).
Since then, only flashing works, but not debugging (stops with the message: "Connection closed by the GDB server.").
I tried PC reboots with a connected and not connected board, I also tried project cleanup + rebuild - but this project seems to be corrupt somehow.
Also removing the whole "Debug" directory manually and do a rebuild is also not enough.
Intrestingly, only this project is non-functional, I set up some other test projects as well yesterday, these still work - which fits to the other posts above...
So I did some more experiments and figured out that it is sufficient to rename the project and rebuild it.
So the debug binary gets a new name and debugging is possible again. Maybe it is just some file permission issue or caching problem of the debugger tools and/or Win7...
