안녕하세요. 항상 많은 도움을 받고있는 왕초보입니다.
현재 루트파일시스템을 yaffs2 로 바꾸려고 포팅중입니다.
고도리님 말씀대로 로그 첨부합니다.^^;;
추가 현재 쓰는 nand 데이터시트와 적용한 패치파일을 첨부합니다.
* 커널버젼 : 2.6.32.2
* Nand : 512m (모델 : NAND04GW3B2D)
* CPU : Ppc440
* board : 회사개발보드
순서는 다음과 같이 진행했습니다.
-. yaffs사이트 에서 최신버젼 (yaffs2-d43e901.tar.gz)다운.
-. 압축 풀고 커널 패치.
(# sudo ./patch-ker.sh c m 커널path)
-. make menuconfig에서 yaffs옵션 선택
-. make 커널 -> 커널이미지 생성 및 타겟보드에 fusing
-. utils에 들어가서 make 해서 mkyaffs2image 생성.
-. 생성된 바이너리로 루트파일 시스템 이미지 생성.
(sudo ./mkyaffs2image 파일패스 이미지이름)
-. u-boot에서 루트파일 시스템영역에 yaffs2이미지 fusing.
nand.write.yaffs2 추가 수정 소스 (http://lists.denx.de/pipermail/u-boot/2010-January/066156.html)

1.6.3.3
------------------------------------------------------------------------. u-boot에서 mtd_args에서 boot type을 yaffs2로 변경.
그리고 부트하면 No init found try passing init option to kernel 메세지가 나옵니다.
커널패치확인을 위해 jffs2파일시스템으로 커널 부팅후
cat /proc/filesystem으로 yaffs,yaffs2 확인하였습니다.
혹시 몰라 mtdblock7을 만든 후, 테스트yaffs2 파일을 u-boot에서 write를 하고
커널에서 mount /dev/mtdblock7 임의폴더/ 로 하면
lost+found 폴더만 보이고 제가 넣어놓은 파일들은 보이지 않습니다.
정리하면 증상은 다음과 같습니다.
-. yaffs2 루트파일시스템 : No init found try passing init option to kernel
-. 커널에서 mtdblock mount : lost+found 폴더만 나옴
-. 커널에서 테스트 yaffs이미지 직접 마운트 : 마운트 안됨 ( 에러메세지도 없음 )
인터넷에서 좀 찾아보니, mkyaffs2image.c 소스를 수정해야된다고 하는데,
수정할부분을 통 찾지 못하겠더군요..ㅠㅠ
(h/w ecc를 disable해야된다길래 했지만 소용없음;;)
고수분들의 많은 도움 부탁드립니다.
감사합니다.
