[U-Boot-Users] boot linux kernel problem

[yu]

Hello. Everyone.
I use ppcboot and linux on a walnut board for test.
I compile the linux kernel source src-linuxppc_2_4_devel from 
ppckernel.org with the command:
make pImage

then I copy the pImage file to walnut board RAM and boot it.
but the linux kernel hang up after the decompression.
What is the possible reason?
thanks in advance.
