보드부팅되고 마운트 확인후 mtdblock3를 /tmp폴더에 마운트 하였습니다.
마운트는 되는데 mkdir명령으로 폴더 생성시 아래와 같은 에러가 발생하네요..
이게 udev때문인지요? 혹시 해당 mtd블록이 yaffs2로 포멧이 되어야하는지요?
그리고 mtdblock4는 마운트가 되지않습니다. 처음에 아래와 같이 마운트는 되었었는데
현재는 마운트 자체가 되지 않습니다.
매번 질문만 하네요.. 저도 답글 달수 있는 날 이 오겠지요..
그때까지 고수님들 도움 부탁드립니다.
질문들을 올리다 보니 스터디도 하고 공동 작업도 하시는것 같던데 혹시 저도 참여할 수있는 방법이 있는지요..
