3.2.3 Target Debug Agent

The target debug agent functions much like the monitor does but with one added feature: the target agent gives the host debugger enough information to provide visual source-level debug capability. Again, an agreed-upon communication protocol must be established between the host debugger and the target agent. The host debugger is something that the host tools vendor offers. Sometimes a RTOS vendor offers a host-based debugger simply because the debug agent is an integral part of the RTOS. The host debugger vendor works closely with the RTOS vendor to provide a fully compatible tool. The debug agent has built-in knowledge of the RTOS objects and services, which allows the developer to explore such objects and services fully and visually.
