linux&arm内核移植问题

 

启动信息如下：
List of all partitions:

1f00       1024 mtdblock0 (driver?)

1f01       3840 mtdblock1 (driver?)

1f02       3072 mtdblock2 (driver?)

1f03      61440 mtdblock3 (driver?)

1f04      61440 mtdblock4 (driver?)

No filesystem could mount root, tried:  ext3 ext2 cramfs msdos vfat romfs

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,3)

求高手怎么解决问题啊，是什么出来问题？
