안녕하세요.
jffs2 mount 에러에 대해서 문의를 드립니다.
아래 메세지를 보니 mkfs.jffs2의 버전과 커널의 jffs2드라이버의 버전이
틀리다고 나오는 것 같습니다.
커널은 2.4.25 (denx홈에서 받은거)이고요
mkfs.jffs2는 여러가지를 받아서 해봤는데 1.7, 1.9
그리고, 페도라3에 들어 있는거 등등을 해봤는데 같은 메세지 입니다.
메세지는 커널드라이버 쪽이 새것이고 mkfs.jffs2쪽이 오래된 것이라고 나오는데
커널이 2.4라서 오래 된 것이고 mkfs.jffs2쪽은 새로 받은 것들이라서
새거 같은데요.
아래 메세지가 mkfs.jffs2와 jffs2드라이버 버젼이 틀려서 그런거 맞을까요?
아니면 다른 프로그램의 버젼이 틀려서 그런 것일까요. ㅜ.ㅜ
고수님들 부탁드립니다.
