内核和根文件系统移植问题

悬赏园豆:5 [待解决问题]

最近在搞内核和根文件系统的移植,但是当我把内核和根文件系统通过uboot烧写到开发板(我所使用的是TI的dm6467开发板)中以后,启动内核时,就出现了如下的错误:

Cowardly refusing to erase blocks on filesystem with no valid JFFS2 nodes

empty_blocks 1536, bad_blocks 0, c->nr_blocks 3520

VFS: Cannot open root device "mtdblock3" or unknown-block(31,3)

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

1f00             128 mtdblock0 (driver?)

1f01            1280 mtdblock1 (driver?)

1f02            4096 mtdblock2 (driver?)

1f03           56320 mtdblock3 (driver?)

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

因为我自己是刚刚接触这一块不久,还请大家帮帮忙,指导指导。谢谢啦!
