안녕하세요. s3c2440 보드로 공부중인 학생입니다.

 

현재 ramdisk 모드로 되어있는 것을 yaffs모드로 변경하려 하는데요.

 

강좌&팁에 있는 강좌물을 보면서 몇번을 수행해봤는데 계속해서 커널 패닉이 발생하더군요.

 

ramdisk 모드로 부팅하고, mount로 mtdblock2를 마운팅해보면 마운트는 되더라고요..

 

ramdisk모드로 부팅한후 ./mkflashroot 유틸리티를 실행한후 재부팅, 그후에 부트로더에 들어가서 yaffs 모드로 부팅모드를 변경한후

 

다시 부팅을 실시한 로그메세지를 밑에 첨부합니다.

 

고수님들 도와주세요..ㅠㅠ
