Hello
Message "Illegal Breakpoint" pops up if application reaches a BGND instruction, while there is no breakpoint defined at that location.
Are you using BGND in your application?
If not the code my have jumped to an invalid location for some reason.
"Triggers A and B occurred" may arises if you have defined triggers in a previous debug session and the markpoint or the DBG module has not been reset for some reason.
Click right in the source window and select "Show Breakpoints". Switch to Markpoint tab and delete all markpoints.
You can try to switch the board OFF and ON again after a minute. That should reset the DBG module.
