Yes, you are right, i was using the wrong one. Now I installed the
toolchain for 6xx and use the env-variable:
export CROSS_COMPILE=ppc_82xx-
- kernel compiled as before and is booting (again configured with the
xenomai prepare script and the adeos patch)
But when compiling xenomai, still the same issue.

it does not seem like that :-(

Thanks for this information having ppc and powerpc is little confusing.

I'm using the ELDK 4.1 Toolchain (ppc-2007-01-19.iso)
The complete log is attached.
