UBIFS启动错误

问题描述:

我有一个基于SAM9的电路板运行嵌入式Linux。UBIFS启动错误

我有一个JFFS2文件系统,现在想转移到UBIFS。

我启用了UBIFS作为目标文件系统,在make menuconfig的buildroot包中使用了我的板子。

我生成了rootfs.arm.ubifs文件,我使用bootloader的nandwrite实用程序以我用于.jffs2文件的相同方式闪存在板上。

我也改变了bootargs到:

setenv bootargs 'console=ttyS0,115200 rw ubi.mtd=1,2048 rootfstype=ubifs root=ubi0:rootfs'

但我发现了以下错误,引导板:

这是一个猜测,但你ubinize你的rootfs在闪存到原始NAND之前?

http://www.linux-mtd.infradead.org/doc/ubifs.html#L_usptools

The images produced by mkfs.ubifs may be written to UBI volumes using 
ubiupdatevol or may be further fed to the ubinize tool to create an UBI 
image which may be put to the raw flash.

谢谢!这工作:) ...我ubinized rootfs闪存到NAND和它的工作。 – androidFan 2012-04-05 05:50:49
