Who know the reason of in the picture just when I debug used IAR7.4?
Thank you very much!
99% percent sure that it is because you haven't programmed any code to the processor.
Make sure that you don't have the debugger set up to not download code - use download and connect, and not just connect.
Yes ,that is focus what I have to ask . I had download and connected to device , but why it can not to download in or debug ?
