看起来，没什么问题一样，但是ubi是否挂载上了呢？怎么看
或者说，这个"root="参数不对？
setenv bootargs console=ttyS0,115200 ubi.mtd=2 root=ubi0_0 rootfstype=ubifs
=>root=ubi0:rootfs 试试 dds 发表于 2012-4-29 14:15 static/image/common/back.gif
setenv bootargs console=ttyS0,115200 ubi.mtd=2 root=ubi0_0 rootfstype=ubifs
=>root=ubi0:rootfs 试 ...
这种办法试了一下，也不行，一样的现象和提示 abnerle 发表于 2012-4-29 14:40 static/image/common/back.gif

那就 root=ubi0:mtd2_ubifs dds 发表于 2012-4-29 14:58 static/image/common/back.gif
那就 root=ubi0:mtd2_ubifs
还是不行，问题很奇怪啦 已经解决了，kernel太大了，是2.4M，kernel区域装不下了，原来是2M，调整kernel区域变为3M，就好了
