안녕하세요~^^

저번에 한번 질문 드리고 aesop u-boot를 이용해서 부팅은 성공했습니다.^^

완벽하게 이해한건 아니지만 제가 기존에 가지고 있던 u-boot 1.0.0 버전도 부팅해서 커널까진 넘겨봤구요.

커널에서 겨우 파티션 만드는 부분은 찾았습니다.^^
그동안 왜 안보였는지ㅠㅠ

struct mtd_partition aesop_default_nand_part[] = {
        {
                name:                "NAND partition 0 : Bootloader BY 64M",
                offset:                0,
                size:                (384*SZ_1K),
        },
        {
                name:                "NAND partition 1 : Kernel BY 64M",
                offset:                (384*SZ_1K),
                size:                (2*SZ_1M) - (384*SZ_1K),
        },
        {
                name:                "NAND partition 2 : Filesystem BY 64M",
                offset:                (2*SZ_1M),
                size:                (32*SZ_1M) - (2*SZ_1M),
        },
        {
                name:                "NAND partition 3 : Data Area BY 64M",
                offset:                (32*SZ_1M),
                size:                (32*SZ_1M),
        },
};

이런식으로 파티션을 만들었습니다. 그리고 nand의 0x200000번지에 기존에 제가 가지고 있던 cramfs파일시스템을 올렸습니다. 근데 안되네요~

커널로그는 아래에 붙여놨습니다.

제가 기존에 cramfs용 파일시스템 이미지가 있는데 이 이미지를 cramfs로 부팅을 하기 위해서는 aesop 커널을 수정해야 할까요? 수정해야 한다면 대략 어떤 방식으로 해야 할지 방향 지시 부탁드리겠습니다.^^

혹시 cramfs가 어렵다면 yaffs나 다른파일시스템 올리기가 더 쉬울까요?

수고하십시요.^^
