Abstract
Q+P Esto는 정보가전용 RTOS인 Q+P를 위한 원격 개발 환경이다. 타겟에이전트는 타겟에서 실행되면서 호스트에 있는 디버거와 원격쉘, 그리고 자원모니터 같은 Q+P Esto 도구들이 원격 개발을 하는데 필요한 기본적인 기능들을 제공한다. 본 논문은 GNU gdb 5.0에 있는 gdbserver를 이용하여 타겟에서 실행 중인 응용 프로세스를 감시 및 제어하는 구조를 제안한다. 디버깅을 위하여 정지점(breakpoint)에 걸린 응용 프로세스를 continue 시켰을 때 응용 프로세스가 무한 루프에 빠지더라도 타겟에이전트는 다른 도구의 요청을 계속 처리할 수 있다. 응용 프로세스를 제어하는 자세한 메커니즘은 gdbserver가 담당한다. 따라서, 타겟에이전트는 단지 gdb remote protocol만 사용하여 gdbserver와 통신하면 되므로 구현이 용이하다.
