This section is intended for users not familiar with GDB. It presents example debugging session from Eclipse using
simple application available under get-started/blink and covers the following debugging actions:

2. Setting and clearing breakpoints
3. Halting the target manually
4. Stepping through the code
5. Checking and setting memory
6. Watching and setting program variables
