Thank you. 보드에 업로딩중에 문제 발생. 다음을 참고하세요. http://www.arduino.cc/en/Guide/Troubleshooting#upload 다른 컴퓨터로 해도 동일하게 오류가 발생하며.. 다른 보드를 연결시에는 정상적으로 작동함을 확인했습니다. 문제가 발생하게된 시간은... 아마도 보드의 reset버튼을 누르고 난 후 일것으로 추정됨. 코드는 아무런 내용이 없는 빈 소스파일을 업로드 시켜보았지만. 역시 마찬가지로 액세스 거부 당했습니다. 포트 또한 문제가 없었으며 보드도 아두이노 uno 로 설정하였습니다. 이 문제를 어떻게 해결해야 할까요?
