Trace and Profile

The P&E TraceLink allows the user to capture real-time external trace information without having to stop or disturb the running application. This allows the user to see the real-time execution of their code by continuously recording the processor events. For external trace captures, the P&E TraceLink must have PST_CLK and DDATA[3:0] pin connections from the ColdFire chip. Chips without these pins connected can still be debugged by the TraceLink within CodeWarrior. The user must do the following to set up external trace captures using the TraceLink.

1. Right-click on the project and right-click -> Debug as -> Debug Configurations. The Debug Configuration dialog box will appear.
2. In the left column, select the project type for which you would like to set the TraceLink settings.
3. In the right column, select the Trace and Profile tab..
