Trace associations are stored in the debug hardware configuration
file (.rvc). However, you can save the associations
in a separate file, if you want to provide the associations to other
users using a similar development platform.
Trace associations are required to describe the associations between the processors and the trace-related devices in complex CoreSight systems. Examples of such associations are:
processor outputs into an ETM
ETM outputs into an ETB
ETM input from a particular processor
CoreSight ETM outputs into a Trace Port Interface Unit (TPIU)
TPIU input from a particular trace source
ETB input from a particular trace source.
Your debug tools use the associations in the debug hardware configuration file to determine the components that must be programmed for tracing a specific source in the system
Associations have direction, and some are bi-directional. You must configure associations correctly to enable your debugger to associate trace output with the source of generated trace.
Although a trace association might be created for a non-CoreSight system, do not modify it.
