Sorry for reporting so late.

But as my tests did not yet include starting up my board I did not notice
that changes (probably between 2006-05-10 19:30 and 2006-05-11 20:31) made
my board unbootable. 

The board hangs after emitting "(Engines Of Creation) loaded." output is:
ocp: exit
arch: exit

Xenomai: real-time nucleus v2.2-rc1 (Engines Of Creation) loaded.

I have no ideas why, as my PowerBook is running fine with an actual Xenomai
based kernel. But I now that the timer architecture for the PPC40x family
is quite different to the PPC en general.

Any ideas where to begin debugging? I am familiar whith the timer/interrupt
architecture of the PPC405 but a hint would be welcome. I will take my BDI
debugger from Abatron home to have a look where the processor hangs, but
will not have time till tomorrow or Wednesday to dig into this problem.

Best regards
