AM3517을 쓰는 커스텀 보드가 있습니다 외주 업체에서 받았는데요
UBI 파일시스템이 들어 있던데 파일시스템이 너무 자주 깨져서
(NAND 플래시)
YAFFS2 파일시스템으로 바꿀려고 하는데 잘 안되네요
http://processors.wiki.ti.com/index.php/Filesystem_in_NOR_or_NAND
여기를 보고 커널에 YAFFS2 패치해서 포함 시키고 설정 해서 빌드 했습니다
그리고 파일시스템은 UBIFS 만들때 쓰던 폴더를 mkyaffs2를 이용해서 만들었고요
(mkyaffs2 rootfs/ 파일명)
u-boot 에서
AM3517의 메모리 맵대로 위에서 압축한 파일시스템을 0x00780000에 올렸습니다
그리고
setenv bootargs console=ttyO2,115200n8 root=/dev/mtdblock3 rootfstype=yaffs2 rw mem=256M
이렇게 설정했습니다
root=/dev/mtdblock를 mtdblock0에서 mtdblock5까지도 변경해봤고
init = /sbin/init 도 추가해봤지만 여전히 에러가 나네요
아래가 부팅 메세지 인데
YAFFS2 파일시스템으로 바꿀려면 어떤 작업이 더 필요한지 궁금합니다
정말 감사합니다^^

음. TI가 아직 ARM AP를 내놓고 있군요. 접은줄알았는데...
왜 굳이 오래된 커널과 파일시스템을 사용하시려는지 잘 이해가 안되네요.
