안녕하세요.
일단 아래 디버그 메세지가 이상한 것은 윈도우의 기본 프로그램인 하이퍼 터미널에서 바로 긁어서 대충 붙여 넣어서 그런 것이구요. (하이퍼 터미널은 스크롤 지원이 뭔가 굉장히 특이하더군요 -_-;)
실행은 알려주신 것 그대로 했습니다. 조금도 다르지 않구요. 올려주신 소스는 이따 테스트 해보겠습니다.
근데 지금 더 중요해진 것은 자꾸 커널 패닉이 나온다는 것과 점점 그 횟수가 잦아진다는 것입니다.
말씀하신 것처럼 이더넷과는 상관이 없네요. 이더넷을 뽑아놓아도 한참 두면 D3, D4, D5 led 가 일제히
점멸하기 시작하고, 그 이후 보드를 껐다켜면 무조건 커널 패닉이 나네요. 한참이란 건 대충 10여분 정도입니다. 그러다가 한 10분 뒀다가 다시 하면 또 멀쩡하네요. 심지어 커널 패닉도 아니고 Segmentation fault 도 한번 났었습니다. -_-; 부팅하다 말고 그러니 굉장히 당황스럽더군요.
개발을 진행을 못할 지경이어서 보드를 바꿔야하나.. 를 생각중입니다.
어떤 문제일까요? 전원 문제일 수도 있는건지요?
답변 부탁드립니다.
참고로 커널은 고치지 않았습니다.

>>led 깜빡이는 예제를 돌리다 보면 이더넷이 연결됐다 끊어졌다를 반복합니다.(led 는 안깜박입니다 -.-;)
>>그러다가 D3, D4, D5 led 가 일제히 점등을 하면서 nfs 연결이 끊어집니다.
>>그러고 타겟보드를 리셋하거나 껐다켜면 부팅 도중 커널 패닉에 빠집니다.
>>2대를 사갔는데 2대 모두 그러네요.

>>왜 그런가요?

일단 아래 디버그 메세지가 이상한 것은 윈도우의 기본 프로그램인 하이퍼 터미널에서 바로 긁어서 대충 붙여 넣어서 그런 것이구요. (하이퍼 터미널은 스크롤 지원이 뭔가 굉장히 특이하더군요 -_-;)
실행은 알려주신 것 그대로 했습니다. 조금도 다르지 않구요. 올려주신 소스는 이따 테스트 해보겠습니다.
근데 지금 더 중요해진 것은 자꾸 커널 패닉이 나온다는 것과 점점 그 횟수가 잦아진다는 것입니다.
말씀하신 것처럼 이더넷과는 상관이 없네요. 이더넷을 뽑아놓아도 한참 두면 D3, D4, D5 led 가 일제히
점멸하기 시작하고, 그 이후 보드를 껐다켜면 무조건 커널 패닉이 나네요. 한참이란 건 대충 10여분 정도입니다. 그러다가 한 10분 뒀다가 다시 하면 또 멀쩡하네요. 심지어 커널 패닉도 아니고 Segmentation fault 도 한번 났었습니다. -_-; 부팅하다 말고 그러니 굉장히 당황스럽더군요.
개발을 진행을 못할 지경이어서 보드를 바꿔야하나.. 를 생각중입니다.
어떤 문제일까요? 전원 문제일 수도 있는건지요?
답변 부탁드립니다.
참고로 커널은 고치지 않았습니다.
