Debug runs immediately after downloading

I am having a problem on some of my boards. The one in particular was working fine, then after chaning code and downloading, the code runs immediately in the debugger. When I try to stop the execution, it fails to show the stepping code. I have two boards that did this right after assembly. This board was running fine, then the problem started. I can not find a way to return it to the previous working state.

Hit the Suspend (Pause) button and you'll see where it is.

My guess is that you have hit an exception somewhere before the breakpoint on main().

This is what I get when I hit PAUSE:

Hi,

It looks like you might have a stack problem. I suggest that you change the initial breakpoint to be the Reset Handler and then step through your code to see where it is going wrong. See:

HTH,

Thanks for the suggestion, but it still does it. If I hit the RESET button to reset the debug session, it runs immediately. Upon stopping, it gives no information. It does not even stop at the "[SIZE=2][B]ResetISR" [/B]that I set as the stop point. The other board does. [/SIZE]
[SIZE=2][/SIZE]
[SIZE=2]Could it be a JTAG problem? It seems to be related to hardware, not software since I have a good working board.

You are right - it sounds like a hardware problem. However, given that no errors are reported, I don't think it is the debug connection (SWD - not JTAG!). You should check power.
