[project 0] 장비교체 후 부팅시 교체 전과 동일한 증상 #12

안녕하세요,

정말 감사하게도 오늘 조교님께서 완전히 신품으로 부품들을 교체해주셨습니다만, 교체 전과 완전히 같은 문제를 겪고 있습니다. sudo screen /dev/ttyUSB0 115200 을 실행하고 전원을 인가하면 다음과 같은 메시지가 출력된 후 idle한 상태를 유지합니다.

OS는 ubuntu 20.04 입니다. 어쨌든 로그인을 할 수가 없으니 뭔가 문제가 있는 것 같긴 합니다만, 부품에는 문제가 없을텐데 제 노트북에 문제가 있는걸까요?

감사합니다. 이영원 드림
