2410보드에 sd card를 mount하려고하는데 잘 안되네요~
커널은 2.6.13버전의 이재훈님게서 만들어놓으신것을 사용하였습니다.
물론 커널 옵션에 fat, ntfs등 file system을 체크했습니다.
u-boot 1.1.2를 사용하여 fatinfo mmc 0으로 확인해보니 다음과 같이 확인할수 있었습니다.

SMDK2410 # fatinfo mmc 0
Interface:  MMC
  Device 0: Vendor: Man aESOP1 Snr 123456 Prod.: SDxxxMB Rev: 123 456
            Type: Hard Disk
            Capacity: 489.5 MB = 0.4 GB (1002496 x 512)
Partition 1: Filesystem: FAT16 "NO NAME    "

램디스크에는 /dev/mmcblk0이라는 디바이스가 없어서
cat /proc/devices로 mmc가 254로 잡혀있는 것을 확인하고
mknod /dev/mmcblk0 b 254 1로 만들어놓았습니다.
sd card는 윈도우상에서 fat로 포맷을 하였습니다.
하지만 커널 부팅후 다음과 같이 파티션을 인식하지 못하더군요.
그래서 mount -t vfat /dev/mmcblk0 /mnt/sd로 마운트를 시도해보았으나
No such device or address라는 에러와 함께 마운트가 안되더라구요.
당췌 무엇이 문제길래 이리도 속을 썩이는지 모르겠습니다.
고수님들의 한 마디가 저에게는 큰 도움이 됩니다~~^^;;
나른한 월욜 오후 수고하십시요~~~~

참고로 /dev의 장치들입니다.
