Configure Project for Profiling

You need to configure the compiler and linker settings of your project. The compiler and linker using the profiler library generate a new version of your program ready for profiling. While it runs, the profiler generates data.

To configure the project for profiling:

1. In the Tool Settings tab page, modify the Entry Point value as __start.
2. In the Force Active Symbols section, remove the entry for __vect by clicking the Delete button.

10. Expand the Project_Settings > Linker_Files node of your project in the CodeWarrior Projects view.
11. Double-click the M5485EVB_Console_External_RAM.lcf file to open its contents in the editor area.
12. Add the following statements at the end of the file before the last closing parenthesis:

    gCWProfileLibraryBuffer = _gCWProfileLibraryBuffer;

    CWProfileDataReady = _CWProfileDataReady;
