9. Click the Step Over icon until you reach the second breakpoint. Note that if the development

board is connected to the SuperSpeed host, the debugger will reach the second breakpoint. If the

development board is connected to the high-speed host, the debugger will not reach the second

breakpoint, because the initial state of the blue LED (LED2) is that it will stay on. This part of the

code is in an infinite loop and clicking Resume will make the debugger stop at the first and

second breakpoints one after the other. Use the Step Into or Step Over icons when required.

Note All FX3 SDK APIs should be "stepped over". "Stepping into" FX3 SDK APIs (APIs are the

function calls that start with "CyU3P" in the firmware) will result in a warning message of "source

not available at…". If you encounter this message, click the Step Return icon.

10.To stop the debug session, click the Terminate icon (see Figure 3-28). When the debug session

is terminated, it can be launched again with the Debug Configurations icon shown in Figure 3-31.

Be sure to reset FX3 before loading the debug configuration again. Clicking the drop-down arrow

of the Debug Configurations icon will display all the debug configurations available. You can

select the desired debug configuration from the drop-down list.
