C2 cvbs 문제

Unread post by jason8098 » Sun Mar 15, 2020 11:56 am

제가 아래 모니터랑 c2 를 연결할려고 하는데요, 공식 사이트에 나온걸로 해도 안되서 문의드립니다.

분명 모니터가 정상인것은 확인했고, boot.ini 도 수정했고, hdmi 출력도 확인 했고, c2 cvbs 연결도 제대로 했습니다. 그런데도 모니터에 아무 반응도 없습니다.

운영체제는 안드로이드 6.0.1 입니다.

분명 출력이 디지탈이거나 해상도가 높게 출력되고 있는것 같습니다만..
어떻게 해야 햐까요?

참고 사이트:

이부분은 제가 납땜기가 없어서 그렇습니다.

이건 제 boot.ini 입니다.

안드로이드 6.0에서 CVBS 출력이 정상 동작하는지 추후에 확인해 보겠습니다.

우분투 이미지로 하드웨어 연결에는 문제가 없는지 먼저 테스트 해보시길 바랍니다.

혹시 밑의 아답터를 이용하면 될까요?

답변이 늦어져서 죄송합니다.
안드로이드 6.0.1에서 CVBS 출력이 되지 않습니다.
WIKI 작성 당시의 버전이 5.1.1이고 그 당시 버전의 없어서 마지막 버전으로 확인해 보았지만 되지 않습니다.
조금 오래된 내용이라 확인하는데 좀 더 시간이 필요 할 것 같습니다.
이용에 불편을 드려서 대단히 죄송합니다.

boot.ini 파일을 다음과 같이 바꿔 보시기 바랍니다.

setenv hdmimode "480cvbs"
setenv cvbs "480cvbs"

setenv display_autodetect "false"

hdmimode=${hdmimode} cvbs=${cvbs} ${cmode}
