안녕하세요
현재 ez-s3c2440과 5.7인치 lcd를 사용중에 있습니다.
장시간 전원 off된 상태에서 스위치를 on시키면 부팅이 정상적으로 이루어 지는데 프로그램 실행후 (qt)  먹통이되거나
제 부팅시 아래의 메세지 이후 다시 먹통이 됩니다.
정상적으로 부팅 하고자 하면 다시 5분 정도 전원을 off 시킨후 on를 시키면 정상부팅이 되는데 리셋 스위치나 전원 스위치를 바로 off -> on 시키면 아래 메세지 이후 부팅이되지 않습니다.
혹시 이러하신분 계신지요? 답변 부탁드립니다.

ps.
부팅 완료시 팽귄 그림과 커서만 깜빡그립니다. 보드 처음 받았을때는 로그인 화면이 나왔었는데요 커널 / 램디스크 바꾼
이후로는 팽귄 그림만 나오네요.
아래에 같은 질문이 있던데 답변 주신되로 해도 증상은 같습니다. 다시 한번 확인 부탁드립니다.
한가지만 더요 ^^;
qt 4.3.3으로 포팅까지 했습니다만 프로그램 실행시 타킷 머신이 다운됩니다. 콘솔도 멈춰버립니다.
실행시키면 터치도 동작합니다만 상하가 반대로 동작하다가 10초 정도 후에는 멈춰버립니다.
혹 이것이 qt에서 터치관련 사항 때문인지요? 아님 다른 이유인지 ... 이것 때문에 2주정도 고생 중입니다.

행복하세요. ^^*
