I don't think you have to add any VHDL Code for the ppc (2 of them on my V2)
But I use a Kernel from here
http://git.xilinx.com/cgi-bin/gitweb.cgi?p=linux-2.6-xlnx.git;a=summary
because there are already some drivers for my Evaluation Board intergrated.

I already got some trouble. But this could also be because I don't know 
what exactly to do. Is there a good Step by Step howto you know? I don't
think one of the howtos at the xenomai site explains how to setup xenomai.
What is this ipipe thing?


>Which framework ?

An application, basing on this framework (written by someone at my college, 
who isn't here anymore), which bases on rtai, was running on linux on a celeron.
This application should be ported to the Virtex 2 Pro by me. So I ask myself how 
hard it would be, to use Xenomai (perhaps with this "rtai skin??") instead of rtai. 

Thank you for you answer and help.
Greetings
Joachim
