but I do not know the place of the IAR forum, the question is while enter debugging, the message below shown, or refer to attached file. The C-SPY option ''Run to 'main''' is enabled,but due to a lack of breakpoints this will require single-stepping ,which may take a long time. Do you want to execute anyway,or stop at the first instruction? only one breakpoint can be set under this condition! why and how to get it right?
