3.6.2. Debugging and Tracing

Try these first

1. 1.

   What is a breakpoint?

   Hint

   Think about how you can pause a movie.

2. 2.

   Why is debugging important?

   Hint

   Consider what happens if there are bugs in your favorite software.

3. 3.

   What does the Serial Wire Debug (SWD) interface allow developers to do?

   • Compile code
   • Real-time debugging
   • Change hardware settings

   Hint

   Think about how you can track what happens while your program runs.

4. 4.

   True or False: Instrumented Trace only helps in gathering data post-execution.

   • True
   • False

   Hint

   Consider if tracking something while it's happening is possible.

5. 5.

   Design a small embedded project involving the ARM Cortex-M0 that requires real-time debugging. Outline what debugging features you would use and explain their relevance.

   Hint

   Think about what happens in a robotics application and how immediate feedback can affect performance.

6. 6.

   Given a sample code snippet with a known bug, develop a strategy for using breakpoints and Instrumented Trace to identify and resolve the issue.

   Hint

   Visualize the flow of the program and how you can pause to check the state at critical moments.
