2.6.24 移植 不能找到NAND 分区求助。

我按照kasim 的 帖子做的，下载到开发板后启动，总是不能找到mtb分区，不知道是什么原因呢。
日志如下：

正常情况，这儿应该要打印出分区的信息的。



希望[url=profile.php?action=show&uid=27]kasim[/url] 大大 能给予指点。

你需要在内核命令行上指定MTD的分区表，格式如下：
mtdparts=qq2440-nand:0x00030000(u-boot),0x00004000(u-boot_env),0x00200000(kernel),0x000a0000(splash),0x03d2c000(rootfs)

按照 您说的做了 ，我是按照2.6.13的分区 改的(2.6.13 启动是正常的 ，bios是vivi) .
2.6.13 定义是这样的
    [0] = {
        .name    = "vivi",
        .size    = 0x00030000,
        .offset    = 0,
    },   
    [1] = {
        .name    = "kernel",
        .offset = 0x00050000,
        .size    = 0x00200000,
    },
    [2] = {
        .name    = "rootfs",
        .offset = 0x00250000,
        .size    = 0x03dac000,
    }

内核参数我是这样加的 mtdparts=qq2440-nand:0x00050000(vivi),0x00200000(kernel),-(rootfs)








但是现在出现了这个错误哈

TCP cubic registered

NET: Registered protocol family 1

NET: Registered protocol family 17

RPC: Registered udp transport module.

RPC: Registered tcp transport module.

drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

VFS: Cannot open root device "mtdblock2" or unknown-block(31,2)

Please append a correct "root=" boot option; here are the available partitions:

1f00        320 mtdblock0 (driver?)

1f01      2048 mtdblock1 (driver?)

1f02      63168 mtdblock2 (driver?)

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,2)

抱歉，忘了说了，这个内核不支持Yaffs，如果你用的是这种类型的文件系统image，需要自己加补丁

哦，谢谢，我试试看
