S3C2440 커널과 램디스크 올리는데 질문입니다..

커널은 강좌를 보고 2.6.28.10 을 올렸습니다..  

램디스크는 1.11-16M를 사용하였습니다. 1.12-24M는 부팅이 되질않아서...

제일 아래쪽에 부팅 로그르 올려놓았습니다. 램디스크로 부팅은 잘되는데 yaffs2모드로 사용하기위해 ./mkflashroot를 실행하면 

mkflashroot ver 1.1 (www.falinux.com)
wait about 20sec ...
backup app
mkdir: Cannot create directory `/tmp/': File exists
copy /bin
copy /dev
copy /etc
copy /home
copy /lib
copy /root
copy /sbin
copy /tmp
copy /usr
copy /var
mkdir ...done
restore app

please reboot system and enter EZBOOT->set
Select >> LF
: will be changed [noinitrd root=/dev/mtdblock2]

이런 메세지가 뜨길래 df를 쳐보니

Filesystem 1k-blocks Used Available Use% Mounted on
/dev/ram 15863 13470 1574 90% /

파일 시스템에 ram뿐이었습니다. 원래 mtd는 보이질 않는건가요? 마운트 하려고해도 no such device라고만 떠서 현재 진행이 되질 않고있습니다.

지금부터 flash로 루트 파일 시스템을 옮겨서 작업을 하고싶습니다.
