first steps with debugger

HI, first english is not my natural language and I have somme difficulties to understand documentation. Furthermore, there are too much abreviations ...

I am using STM32F7508-dk board. I build a small new app that is supposed to blink led1. But it doesn't work. I started debugging with Keil. The debugger starts but strange things happen.

I set a break point on line 80. But it doesn't stop. The red circle has been replaced with an exclamation. I tried 'use simulator' and 'st-link' in the debugger tab but it is the same thing.

Can someone explain me, in simple words, how to parameter the debugger and why the first break point doen't work ? I am wondering if I need Cube Programmer to send the code to the board before debugging or not.

Thanks in advance

Jean
