PURPOSE: A trace point setting method is provided to set a monitoring trace point at a level of instruction in making a real time development of a software for easily finding a bug occurred during a real time development. CONSTITUTION: The method comprises steps of setting/releasing a monitoring trace point at a host computer, inputting a user instruction for downloading a test program, and performing a corresponding instruction(201), setting/releasing a target trace point for directly inserting undefined exception codes into an application program or recovering an original instruction at a target processor(202), triggering a trace function according to an occurrence of a trap at the trace point while executing the application program(203), receiving a trace message acquired via the trace function triggered at the trace point, and outputting the trace message(204), and correcting errors of the application program found at the debugging process using the trace point(205). The method can include a step of setting additionally a trace point at the application program by executing a trace instruction for adding a trace point. In the additional trace point setting step, a trace point structure is generated by using a trace point context ID and a trace point address for inserting an exception code at a specific position of tasks in the application program and the structure is registered at a breakpoint chain.
