S3C2440 램디스크 변경후 커널 패닉
2010.10.27 23:36
안녕하세요
사이트에 있는 램디스크로 바꾸어 올려 보았습니다.
커널 패닉이 나타나 해결을 위해 이것 저것 찾고 있습니다. (잘 안 되네요 )
램디스크 : ramdisk-1.12-24M.gz
==> 18M디스크를 만들어서 24M 내용물을 복사해 넣었습니다.

========================================================
중간 INIT 부분은 색깔 변경해 놓았습니다.
툴체인을 4.3 으로 바꿔 보려고 램디스크를 바꿀려고 합니다.
감사 합니다.

RAMDISK size 를 바꿔줘도 동일 하네요 ..
18M로 만들어서 1024 * 18 = 18432
20M로 설정 20480
램디스크는 18M로 만들 었습니다.

invalid format 이라고 되어 있습니다.
바꾸어서 만드는 과정을 한번 올려주세요.
만드는 과정을 한번 살펴 보는 것이 좋을 것 같습니다.

네 .. 저도 지금 그부분을 보았습니다.
http://southlife.tistory.com/61 <== 이곳을 보고 램디스크를 만들었습니다.
[root@localhost ramdisk]# dd if=/dev/zero of=R_16M bs=1k count=16384

R_16M is not a block special device.
Proceed anyway? (y,n) y

[root@localhost ramdisk]# mount -o loop R_16M 16M/내용 복사
umount ..
gzip R_16M

혹시 압축 상태의 size 가 5M 넘은건 아닌가요?
s3c2440 보드를 사용하신다면 현재 NAND 파티션이 5M 로 설정 돼 있습니다.
==> 14) nand part (B,C,L,K,R,A): 1,1,2,3,5,1012
파티션 나눈게 사용하시는 보드와 다를수도 있지만 윗줄에 표시한부분을 확인 해 보세요.

참조하셔서 시도해 보세요

===================Message Ending..
이와 같은 증상은 etc나 dev디렉토리의 오류라고 적혀다른곳에서 본것 같네요.
좀더 찾아 보도록 하겠습니다. -- 도움을 주시면 좀더 빨리 해결할수 있을테니 도움도 간절히 기다립니다. ^^

아직 해결을 하지는 못하였습니다. 조금 의심 스런 것이 있다면
/bin/sh ---> ../bin/busybox
/bin/sh --> ../bin/bash
두개의 차이 입니다.
부팅에 문제가 없는 것은 /bin/bash 가 들어 있네요
이것이 아니겠지만. 의심이 되어서 ~ 흔적을 남깁니다.
부트옵션에는 램디스크 사이즈를 정해주게 되어 있습니다.
루트 마운트시에 그 크기를 알기 위해서지요.
방법은 ramdisk=16384 -> ramdisk=1024*원하는 사이즈 가 되겠습니다
이지부트에서는 부팅시 스페이스 누르시고 커맨드 라인이 뜨면
set 하시면 부트옵션을 바꾸는 메뉴로 진입하실수 있습니다.
다른 것은 그대로 두고 ramdisk=숫자 만 바꾸시면 됩니다.
