Hi.

Is there's any chance that  AT91SAM9G45 will be supported in Xenomai?

Regards,
R.

There is always a chance.  Actually there are several options if a
feature does not exist yet:

1) Wait long enough until sombody else submits the needed code.
   Problem: it might take longer than you can afford.

2) Hire an expert.
   Problem: it might cost more than you can affort.

3) Implement it yourself.
   Problem: it might take longer and cost more than you can afford.

That's a _very_ common situation - see signature below.

Everyone who comes in here wants three things:
        1. They want it quick.
        2. They want it good.
        3. They want it cheap.
I tell 'em to pick two and call me back.

Indeed. I knew it was a long shot.

I already have a few boards for experimenting with Xenomai. AT91SAM9G45
has some interesting features with respect to other AT91s.

Thanks,

In cases like yours it is usually a good idea to start reading the
documentation.  For example,
http://www.xenomai.org/index.php/Embedded_Device_Support
will tell you that AT91 in general is supported by Xenomai, so the
eforts needed for your board should be not too big.

On the other hand... I don't know your requirements, but none of the
AT91 processors will actually give whopping real-time performance
(compared to other processors at the same clock rate).  There might be
other, better options.
