기존 이솝 임베디드 포럼의 지식인 서비스가 게시판 형태로 변경되었습니다.
2.6.21 aesop kernel 을 2.6.24 로 바꾸는 작업을 대충 마무리 했습니다.
그런데 이상한 점은 2.6.21 에서 잘 mount되던 SD가 mount가 되지 않았습니다.
아래와 같은 오류 메시지가 나타났습니다.
[root@S3C6410 /]# mount /dev/mmcblk0p1 /mnt

mount: /dev/mmcblk0p1 is not a valid block device
[root@S3C6410 /]#
처음에는 porting 중에 잘못한 부분이 있나 해서 mmc관련 source를 여러번 살펴 보았습니다.
그러다 마지막 줄의 오류 메시지가 눈에 들어왔습니다. " not a valid block device"
앗 그래서 SD/MMC 의 block device No. 를 찾아보니 번호가 바뀌었더군요.

Major No. 가 바뀐게 맞는지 아시는 분 있나요??
device file를 새로 만들어 mount하니 한번에 붙더군요.
메시지 좀 잘 볼껄 괜히 시간만 낭비했습니다.
