[Xenomai-help] Newbie and Coldfire

[Miguel Angel Alvarez]

Hi.

I do not know if this in the correct mailing list to do this question. 
If not, please redirect me to the correct one.

I am beginning a new proyect using a Coldifre micro (Have previous 
experience with i386 and PPC). It is also my first proyect with real 
time linux, so I have began to read articles about preemption patches, 
RTAI...

It seems that Xenomai is the best effort to obtain hard real-time 
characteristics to my system, but... it is not ported to support 
Coldfire. Could anyone give me an advise on the difficulty of porting 
the systen to this architecture? Should I consider it just impossible?

Thanks

Miguel Ángel

Disclaimer: No expert on Coldfire speaking here. But given that Xenomai
already runs fine over Blackfin (also a MMU-less arch) and that it has a
clean architecture abstraction: should definitely be feasible.

The first step always involves an Adeos I-pipe patch. Check available
patches for other archs to assess the required effort for you. Feel free
to drop questions on their design or your Coldfire ideas on
xenomai-core/help or on adeos-main (similar people will listen).

Well. In fact I did a mistake in my previous messages. I am dealing with 
a V4Core Coldfire, so I have MMU. However your comments have been useful 
Jan. Thanks.
