매일 아침에 서버 로그를 보면서 별일 없었나를 확인하는데 접속이 안된다. 최근에 가끔 네트워크 끊김이 발생했던일이 있어서 그냥 껐다 켰는데 여전히 부팅이 안되는 상황이 발생했다.
UART 연결해서 부팅할때 무슨 메세지가 뜨는가 봤더니만…

딱 이부분에서 꺼지더니 재시작을 무한반복하고 있는 상황이었다. 처음엔 뭔가 파일 시스템이 깨진줄 알고 SD카드 교체도 해보고 위 로그중에 의심나는거는 죄다 검색해보는 삽질을 오전부터 오후까지 하고 있었는데… 우연히 어댑터 맛갔을때 무한 부팅이 반복된다는 어느 글을 보고 어댑터가 맛갔나 라는 생각에 테스터기로 전압도 찍어 봤지만 5.12v로 정상 전압이 나오는걸 보고 그냥 흘려보냈었다.
오후 늦게 “이것저것 해볼거 다 해봤다” 라는 생각에 포기하고 새거 살 궁리와 방 정리를 하다가 예전에 벨킨 7포트 USB 허브 어댑터가 5V 4a 짜리라는걸 생각하고 대충 선 잘라서 연결해봤더니
잘켜짐!!!!
일단은 임시로 사용중이긴 한데 빨리 어댑터 하나 더 사서 연결해줘야 할거 같음. 이것도 USB 허브에서 전원 딸림 현상 나타나서 어댑터만 남기고 버렸던거니…
이녀석이 맛간 어댑터인데 HC1 구매할때 같이 구매했던 제품인데 왜 벌써 맛가나 했는데 4년동안 24시간 풀로 굴려댔던거니 갈만도 하지… 수고했다.
