mini2440보드에서는 u-boot보다는 supervivi가 기본드로 들어가 있습니다.
때문에 나와 있는자료도 supervivi와 dnw.exe를 사용하는 것으로 되어 있습니다.
일단 u-boot 전에 supervivi에서 완전하게 작동하는 것을 짚어보고 넘어가보고자 합니다.
1. NFS 마운트 하기!!!
<루트 파일 구해서 풀기>
패키지에 첨부된 root_nfs.tgz를 /opt/FriendlyARM/mini2440/root_nfs에 풉니다.
tar xvzf root_nfs.tgz -C /opt/FriendlyARM/mini2440
으로 풀면 됩니다.
<NFS 마운팅 하기>
그리고 NFS Server 패키지는 인스톨 되어 있어야 합니다.
NFS에서 export할 위치를 설정합니다.
#gedit /etc/exports
를 실행하여
/opt/FriendlyARM/mini2440/root_nfs *(rw,sync,no_root_squash)
를 추가합니다.
#/etc/init.d/nfs-kernel-server start를 실행해서 export가 적용되게 합니다.
(ubuntu 9.10에서는 위와 같이 하고, 다른데는 "/etc/init.d/nfs start"으로 실행해야하는 것 같습니다.)
root@ubuntu:/tftpboot# /etc/init.d/nfs-kernel-server start* Exporting directories for NFS kernel daemon... exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/opt/FriendlyARM/mini2440/root_nfs".Assuming default behaviour ('no_subtree_check').NOTE: this default has changed since nfs-utils version 1.0.x[ OK ]* Starting NFS kernel daemon [ OK ]root@ubuntu:/tftpboot#
확인을 위해 다음과 같이 해봅니다.
#mount -t nfs localhost:/opt/FriendlyARM/mini2440/root_nfs /mnt/
#cd /mnt
#ls -al
해보면 제대로 마운팅 되었다면 리스트가 보일 것입니다.
확인이 되었으면
#cd /
#umount /mnt/
를 해서 언마운트 시킵니다.
2. NFS로 Target System Booting 하기!!!
방법은 Supervivi 부트로더가 실행될때 빨리 스페이스키나 다른키를 누릅니다.
단, 엔터를 누르면 부팅됩니다.
그러면 부트로더 프롬프트가 나오는데, 거기서 nfs관련 파라메타를 등록 합니다.
리눅스 상에서 초기화 관련 부분 인 것 같습니다.
param set linux_cmd_line "console=ttySAC0 root=/dev/nfsnfsroot=192.168.11.103:/opt/FriendlyARM/mini2440/root_nfsip=192.168.11.200:192.168.11.103:192.168.11.103:255.255.255.0:ubuntu:eth0:off"
참고로, 192.168.11.200은 local ip 이고, 192.168.11.103은 NFS Server의 IP입니다. ubuntu는 Server name입니다.
console은 ttySAC0로 UART0 포트를 사용합니다.
그리고 루트 이미지는 "/opt/FriendlyARM/mini2440/root_nfs"에 존재합니다.
위의 명령이 끝났으면,
'boot'를 입력하여 리눅스를 재기동 합니다.
캡춰된 실행 수순은 다음과 같습니다.
