Debugger jumping around in code

I am single stepping through my code, and the debugger will jump to unrelated lines of code, then jump back. Am I using he wrong settings on the debugger? What is the best way to have it set up? I am running code on the Xpresso 1768 board. It does the same thing on my target board.

Are you debugging code built for debug or for release?

From your description it sounds like you are probably trying to debug a release build? If so, then the following knowledgebase entry includes some information on compiler optimization and its effect on debugging:

That did not fix it. If anything, things are worse now. I am getting build errors where none existed before, even in modules I can not access.

I have optimization turned off (O0), and debug level to default (-g), and am set to debug build.

Is there a good base line I can set everything to?

Is there an 'OH CRAP" button that will return everything to good running factory defaults?

The FAQ I pointed you at largely is focussed on explaining optimisation, so it is not immediately clear as to exactly *what* did not fix it. Can you clarify exactly what you did?

What build errors are you actually encountering?

I suggest that you try doing a clean of your project, then build it again. Then copy'n'paste the build log out of the IDE into this thread.
