Thanks Christoph, I succeed to execute the prepare-kernel script and to build linux/xenomai for my target using the Xenomai next branch.

Xenomai v3.0.5 does not support arm64. Try using the next branch. In fact I am using Xenomai-next with I-pipe (Linux 4.11) and (nearly) mainline Linux 4.12.14 kernel on a RK3399 (four Cortex-A53 cores plus two Cortex-A72 cores).
