i2c 프로그램 돌려봤는데.. write에서 Remote I/O error가 뜨네요..

보드 상에서 돌린거고요...

보드상에서 cat /dev/i2c-0 하면..
i2c-dev.o : opend i2c-0
i2c-dev.o : i2c-0 reading 8192 bytes.
cat : read : Remote I/O error
i2c-dev.o:Closed: i2c-0

부팅할때..이렇게..뜨는데..스캐닝버스에서..어드레스를 못찾는 것 같은데..
특정 어드레스만 떠야 하는것 아닌가요...
그냥..아무것도 없이..부팅해도..위와 같이 뜨던데..도무지 모르겠군요..
도대체...어떻게..해야 하는지..ㅜ.ㅜ

이런 에러 뜬적 있으신 분들..도움을 주세요!~~
