Hello everybody!

I've a very strange error. I've running application for stm32f407. I can download the code and it's working well. But when I want to debug with CoIDE the code stopped at 1FFF39c4 so in the system memory. At this point I reset the debugger and the code stop at the main function. I don't know the problem.

Can anyobody help me?
