X5 커널 2.6.10에서 nand-yaffs지원에 대하여 문의 드립니다...

저는 지금 EZ-X5 보드에 커널 2.6.10을 포팅 중에 있습니다. 그런데 nand flash 쪽이 잘 안되는군요...
일단 파일시스템은 yaffs로 지원하도록 커널을 세팅했구요... /proc에서 보면 아래와 같이 나옵니다.

cat /proc/yaffs

cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00200000 00004000 "EZ-X5 Kernel partition"
mtd1: 00800000 00004000 "EZ-X5 Ramdisk partition"
mtd2: 03600000 00004000 "EZ-X5 Data partition 0"

그리고 아래와 같이 mtdblock의 mtd2를 마운트 해보면 메시지가 주루룩 나오면서 마지막 줄에서 실패 했다고 나옵니다.

mount -t yaffs /dev/mtdblock/2 /mnt/nand
yaffs: dev is 32505858 name is "(unavailable)"
yaffs: Attempting MTD mount on 31.2, "(unavailable)"
yaffs: yaffs_GutsInitialise()

mount: Mounting /dev/mtdblock/2 on /mnt failed: Not a directory

이게 어디에서 잘못된건지 알수가 없군요... 혹시 2.6버전에서 yaffs포팅하신 분은 도움좀 주세요....
그리고 강좌란에 사용자 팁에 2.6.9에서 포팅한 패치 파일은 다운이 되질 않는군요....

하여간 제가 방향을 잡을 수 있도록 도움 부탁드립니다...ㅠ.ㅠ
