2.6.29内核移植

我今天尝试移植2.6.39的内核过程没有什么问题.
在烧录时候无法正常进入文件系统.
提示如下:

复制代码 FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive! List of all partitions: 1f00             256 mtdblock0  (driver?) 1f01             128 mtdblock1  (driver?) 1f02            5120 mtdblock2  (driver?) 1f03          125568 mtdblock3  (driver?) No filesystem could mount root, tried:  vfat Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-b0x18/0x1c) r7:00008001 r6:c0020878 r5:c0811005 r4:c0471be8 [<c0316b28>] (dump_stack+0x0/0x1c) from [<c0316ba4>] (panic+0x60/0x190) [<c0316b44>] (panic+0x0/0x190) from [<c0008de0>] (mount_block_root+0x26c/0x2bc) r3:00000000 r2:c0829f60 r1:c0829f60 r0:c03d8e5c [<c0008b74>] (mount_block_root+0x0/0x2bc) from [<c0008e84>] (mount_root+0x54/0x6c) [<c0008e30>] (moun<c0008e9c>] (prepare_namespace+0x0/0x180) from [<c0008474>] (kernel_init+0x104/0x140) r5:c002005c r4:c0471520 [<c0008370>] (kernel_init+0x0/0x140) from [<c0043b80>] (do_exit+0x0/0x6bc) r5:c0008370 r4:00000000

不知道这个是什么错误呢?有劳各位解答下了.

补充下问题.
事实上我有文件系统的.是yaff2.
但是提示找不到..这让我很烦恼..

rootfs…那个文件系统烧进去了吗？把文件系统都烧进去看看
以前遇到过烧完内核之后启动开发板出现过这种情况，再烧入文件系统就没事了
