일반 [re] EZ-EP9312 커널 패닉 질문입니다.
2006.01.25 23:55
안녕하세요..
이상하네요.. 저희가 가지고 있는 보드 몇개를 TEST 해 보았는데.. 전혀 문제가 없습니다...
일단 전원은 어떤걸 사용하나요?? ( 5V/1A 이상을 권장하고 있습니다. )
만약 전류가 부족하면 이더넷부분에서 링크를 못할 수가 있습니다.
전원을 정상적으로 사용하셨는데도 이상이 있으면 A/S를 보내주시거나 또는 보드를 가지고 방문해 주세요.. 바로 확인 해 드리겠습니다..
그럼 수고하세요..

>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 -_-;)

>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.

>>안녕하세요..
>>
>>문서에서 약간 수정할 부분이 있네요..초기 문구에 "타겟보드의 디버깅용으로 달려있는 2개의 LED를 가지고 GPIO 입출력을 TEST 한다." [14장. 1.4.절 ]
>>
>>문서작성시 이 디버깅용으로 할려고 하다가 2개의 LED는 입력으로만 가능하기 때문에 따로 회로도를 꾸며서 사용하는것으로 변경하였습니다.. 이 문구를 바꾸지 못했네요...죄송합니다.
>>
>>일단 소스를 두 종류로 다시 올려 드리겠습니다.
>>
>>1. GPIO 디렉토에 있는것은 문서의 회로도대로 작성한 소스입니다.
>> GPIO-A Port [0..3]
>>
>>2. GPIO-DEBUG 디렉토리는 디버깅 LED로 사용된 GPIO-E Port [0..1]를 ON/OFF 하는 소스입니다.
>>
>>두개의 사용방법은 다음과 같습니다.
>>
>>1. 보드 부팅 후 nfs로 접속한다.
>>
>>2. 해당 모듈과 어플리케이션 실행 파일을 nfs로 복사한다.
>> - dev_gpio.ko
>> - app_gpio
>>
>>3. 모듈을 적재한다.
>>
>> $ ismod dev_gpio.ko
>>
>>4. 디바이스 장치 파일을 만든다.
>>
>> $ mknod /dev/gpio c 240 0
>>
>>5. 어플리케이션을 실행시킨다.
>>
>> $ ./app_gpio
>>
>>
>>이렇게 하시면 됩니다...
>>
>>
>>그런데.. 커널 패닉이 나타난다는 문제는 이상하네요...
>>아래 메세지를 보면 커널부팅시 중간 중간에 어플리케이션이 실행하는 코드가 보이는데...
>>LED 깜빡이는 예제를 어떻게 타겟보드에 실행 하셨는지 적어 주시면 감사하겠습니다.
>>GPIO와 이더넷은 전혀 관계가 없습니다....
>>
>>일단 위와 같이 해 보시고 안되시면 다시 리플달아 주세요..
>>
>>
>>그럼 수고하세요..

>>>카테고리에 EZ-EP9312 가 없네요.
>>>
>>>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.

이상하네요.. 저희가 가지고 있는 보드 몇개를 TEST 해 보았는데.. 전혀 문제가 없습니다...
일단 전원은 어떤걸 사용하나요?? ( 5V/1A 이상을 권장하고 있습니다. )
만약 전류가 부족하면 이더넷부분에서 링크를 못할 수가 있습니다.
전원을 정상적으로 사용하셨는데도 이상이 있으면 A/S를 보내주시거나 또는 보드를 가지고 방문해 주세요.. 바로 확인 해 드리겠습니다..
그럼 수고하세요..
>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 -_-;)

>근데 지금 더 중요해진 것은 자꾸 커널 패닉이 나온다는 것과 점점 그 횟수가 잦아진다는 것입니다.

>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.

>>문서에서 약간 수정할 부분이 있네요..초기 문구에 "타겟보드의 디버깅용으로 달려있는 2개의 LED를 가지고 GPIO 입출력을 TEST 한다." [14장. 1.4.절 ]

>>문서작성시 이 디버깅용으로 할려고 하다가 2개의 LED는 입력으로만 가능하기 때문에 따로 회로도를 꾸며서 사용하는것으로 변경하였습니다.. 이 문구를 바꾸지 못했네요...죄송합니다.
