안녕하십니까? 또 질문을 올리게 되네요...ㅜ.ㅜ;;
nfs로 마운트하고자 하는데 마운트가 안 되는 것 같습니다.
저는 u-boot나 커널이나 루트파일시스템으로 사용할 내용들에는 수정을 하진 않았습니다.
다만 약간 설정을 변경하였습니다.

게이트웨이(공유기) : 192.168.20.1
타겟보드(이솝보드3차) : 192.168.20.105
nfs로 마운트 할 디렉토리:/root/nfsroot/small_2613
혹시 게이트웨이도 설정이 필요한건가요?
나머지 부분은 다 그대로 했는데 마운트가 안 되네요...ㅜ.ㅜ;(패널에는 여우모양만이...^^;;)

답변 주신 분들 너무나 감사드리고요...
여기 까지 와서 NFS 마운트는 성공했습니다.
nfs mount위치는 그냥 제 위치(/root/nfsroot/small_2613)으로 진행했구요....
커널을 다시 포팅해야 되는게 문제였습니다.
테스트 프로그램들 돌려보니 다 되는군요... SDL쪽은 아예 몰라서 해보진 않았구요...ㅎㅎㅎ
어쨌든 제대로 되니 기쁩니다. 이제부터 이리저리 이것저것 해봐야겠네요...
이제 새벽 4시가 다 되어가니... 오늘 하루 좋은 하루 되세요~~~!!!!

여기 까지 와서 NFS 마운트는 성공했습니다.
nfs mount위치는 그냥 제 위치(/root/nfsroot/small_2613)으로 진행했구요....

저도 같은 증상이 나오는데요....
전 host 환경이 vmware에 fedora6을 설치해서 사용하고 있습니다.
bootargs root=/dev/nfs 라고 설정을 하는데
host에서 /dev/nfs를 찾아보면 없는데..
이 파일이 없어서 그런건 아닌지???
혹시 fedora6에서 성공하신분은 없으신가요?

그래서 "" $ hostname"" 이란 명령어로 자신의 리눅스 컴 이름을 알아내서 <host>이분분에 넣어주면 됩니다.
대부분 리눅스배포본 종류에 상관없이 NFS,tftp설정은 같습니다.
중요한것은 고현철님께서 소스 컴파일시 커널과 u-boot이미지 생성 장소를 /korea-dokdo/.....여기 아래로 설정을 하셔서 그렇지 Makefile에서 저부분을 자신이 원하는 작업장소로 변경하면 대부분 리눅스에서는 문제 없이 동작하실겁니다.
