Re: ppcboot, linux , hang at the last step

When I boot a linux image use "bootm ffa00000 ffb00000"

VFS: Cannot open root device "" or 16:01
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 16:01

I have set the "bootargs=root=/dev/ram"

Is this your input, or the putput of the printenv command in PPCBoot?
Remember that you must not use a '=' with setenv!

Is my linux kernel's erro or ppcboot's problem?

Which arguments are really passed to Linux?  The  kernel  prints  the
boor arguments it receives on the console.

Does ppcboot send the bootargs to linux kernel correctly?

It does. Probably you did not specifyu correct boot arguments.
