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..

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..

>그러다가 D3, D4, D5 led 가 일제히 점등을 하면서 nfs 연결이 끊어집니다.
>그러고 타겟보드를 리셋하거나 껐다켜면 부팅 도중 커널 패닉에 빠집니다.
