Hi there,Not sure what you mean by "my CM3 core does not have it (CoreSight Modules)".The Cortex-M3 design included the SWJ-DP and ROM table, so unless it has been removed by the designer, you should be able to access it easily.I would suggest you to contact ARM support team so that we can understand what system design configuration you are using and see what can be done to resolve the problem.regards,Joseph
