(still! ;-) ) I managed to compile the kernel sources from kernel.org (2.6.12.3) with a cross tool chain created with this great script from kegel.com (using demo-ppc440.sh). I set ARCH=ppc and CROSS_COMPILE=powerpc-440-linux-gnu- during the configuration procedure (using xconfig) as well as for the actual buil process. Of course, I also added the path to the ppc-crosstools to my PATH variable. Seems I did all that right, because the build process succeeded. Finally I got an zImage.elf file (among some other variants) after the make process in .../arch/ppc/boot/images which I tried to load via TFTP of the PIBS ROM Monitor. After the image has been loaded into RAM I get a lapidar "error: can not process ELF program header, status: command rc=-1" and that's it... When I examine the image file with readelf everything seems to be all right. All data seems to be plausible and it is in fact a binary for PPC. Anyhow seems to be wrong with the header format... Has anyone a guess what's the problem? Is PIBS not able to load kernel images at all? Or do I have to create another kind of image format? By the way: Do I have to rearrange the default memory mapping of this board to get at least some success with the linux kernel? Thanks for your help and sorry for my lame questioning... I am just new to this domain... Bests, Frank
