[置顶] 64M nandflash分区示意图

这是我的64M的nandflash分区示意图涵盖的文件系统比较多，分区设置代码是在arch/arm/plat-s3c24xx/common-smdk.c：

static struct mtd_partition smdk_default_nand_part[] = {
    [0] = {
        .name   = "bootloader bin",
        .size   = 320*SZ_1K,
        .offset = 0,
    },
    [1] = {
        .name   = "bootloader env",
        .offset = MTDPART_OFS_NXTBLK,
        .size   = 704*SZ_1K,
    },
    [2] = {
        .name   = "linux kernel",
        .offset = SZ_1M,
        .size   = SZ_1M*10,
    },
    [3] = {
        .name   = "rootfs jffs2",
        .offset = MTDPART_OFS_NXTBLK,
        .size   = SZ_1M*8,                                                                        
    },
    [4] = {
        .name   = "rootfs ubifs",
        .offset = MTDPART_OFS_NXTBLK,
        .size   = SZ_1M*8,
    },
    [5] = {
        .name   = "rootfs cramfs",
        .offset = MTDPART_OFS_NXTBLK,
        .size   = SZ_1M*8,
    },
    [6] = {
        .name   = "rootfs yaffs2",
        .offset = MTDPART_OFS_NXTBLK,
        .size   = SZ_1M*8,
    },
    [7] = {
        .name   = "apps partition",
        .offset = MTDPART_OFS_NXTBLK,
        .size   = SZ_1M*8,
    },
    [8] = {
        .name   = "info partition",
        .offset = MTDPART_OFS_NXTBLK,
        .size   = SZ_1M * 8,
    },
    [9] = {
        .name   = "backup",
        .offset = MTDPART_OFS_NXTBLK,
        .size   = MTDPART_SIZ_FULL,
    }
};

不好意思图片上的地址有误：-），下面这个是启动时打印的信息：
