Hello
[quote user="yang liu3"] there is a button "Locate File", but why doesnot see it ? can someone tell me how to enable the button.[/quote]
If you don't see this button, then it means one (or more) of the following:
-no debug symbols available (no code or code where debug symbols were not generated)
-the target is halted at a location where there is no source file correlation
In your case you are halted at _c_int00, which is the default entry point code built with TI build tools. It is part of the runtime library of which there is not debug symbols available.
Thanks
