Kernel compile (linux) for MPC5200B Lite board

I've downloaded the ltib package and installed it.
some problems with one line tho. I installed the newest debian directly from the net on my machine and sed couldn't find any of the standard library because of the line
if [ 'uname -m' != 'x86_64' ]; then
export LD_ASSUME_KERNEL=2.2.5
in one of the ltib/dist/lfs-5.1/ files
by replacing assume_kernel=2.2.5 to the actual kernel version I managed to fix this.
But now to my problem.
I've built a few kernels now and I get a uImage
but the u-Boot complains on inflate() which returns -3
So I decreased the compression to gzip -1 vmlinux.bin
then made the image my self with
/opt/freescale/ltib/usr/bin/mkimage -A ppc -O linux -T kernel -a 00000000 -e 00000000 -n 'Linux-2.6.11-7-ppc' -d vmlinux.bin.gz uImage
works fine, u-Boot says that the checksum is ok and extraction is ok but then the serial link dies or something. I don't get anything more, I think the watchdog kicks in after a while and resets the cpu
Obviously I'm doing something wrong, but what? :smileyhappy:
I've used kernel boot commands:
console=/dev/ttyS0 root=/dev/nfs rw
console=ttyS0 root=/dev/nfs rw
Anyone who could give me some links to previous posts/documents/etc to help me out?

Thanks in advance
