[ECOS] Breakpoints

Lately when I download a file using Insight (by selecting the RUN icon) the
program will download and not stop at my break points.  I use File->Open to
bring up the image and source files.  I then set the break point in
cyg_user_start.  I hit the RUN icon to download the image and then it runs
without stopping at my break point.  Do you know what could cause this
behavior?

Thanks

Sometimes there can be multiple cyg_user_start's floating around, and GDB
chooses the wrong one (it's a known problem), so be sure to set a
breakpoint on the cyg_user_start that actually gets executed.

Also try it on unoptimized code. Debugging optimized code can sometimes
(although fortunately rarely) fail.
