uboot 内核启动参数问题

今天把文件系统和内核烧进去以后，出现如下信息：

Cowardly refusing to erase blocks on filesystem with no valid JFFS2 nodes
Kernel panic: VFS: Unable to mount root fs on 1f:02
    到网络上查了一下，还是内核参数设置不正确，根据上面的启动信息，可知flash分区如下：
Creating 4 MTD partitions on "X-Hyper255 Flash":
0x00000000-0x00040000 : "Bootloader"
0x00040000-0x000c0000 : "Partition Tables"
0x000c0000-0x001c0000 : "Kernel"
0x001c0000-0x02000000 : "Filesystem"
    那么root分区应该位于/dev/mtdblock3，所以将bootargs设置如下
setenv bootargs noinitrd root=/dev/mtdblock3 rootfstype=jffs2 rw console=ttyS0,115200 mem=64M
saveenv
    重新启动后，又出现如下的错误信息
