Running Linux on Avnet's FX12 Evaluation Board

[Benedikt Wildenhain]

Hello,

I am trying to run a Linuxppc 2.4 kernel (20051021) on an IBM Powerpc
405, I have compiled it according to the instructions on
http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/uclinux_powerpc/#linuxppc-2,
I load it into the ram using the Xilinx Microprocessor Debug (XMD)
Engine and try to run it, but it seems to have some trouble with the
memory:

Linux/PPC load:
Uncompressing Linux...done.
Now booting the kernel

Do I have to set any memory positions or something like that manually?
I also tried to compile the Kernel with XMON support, but this also
failed:
