Since this board is a PPC architecture and Orocos supports it, you can port
your application to the embedded system. We are doing almost the same thing
but on a Xilinx Virtex-5 (PPC440). Unfortunately, this is not a trivial task
since you will have to cross-compile every dependency. If you use Corba, I
strongly suggest to use OmniORB instead of ACE&TAO. It's much smaller and
easy to cross-compile. Here is some links that may help you to cross-compile
dependencies:

For cross-compiling Orocos, I suggest to use the CMake approach:

Thank you Philippe,For more
Thank you Philippe,
For more detail:i used Leon3 ,SPARC architecture, for Virtex-2Pro FPGA. I know we must use a cross compiler. But how to install the application on the target platform? and what are the tools we need to install the application OROCOS in the target?
Thank you Philippe,For more

Maybe you can check the recent posts by Zhang Lin, who just succeeded in
running an Orocos application on a Virtex FPGA. It's a PPC architecture,
but the worlflow and toolchain for such cross-platform development is
rather similar between platforms. The essential thing is to find decent
Linux kernel for your hardware.

Hi PhilippeI like to know
Hi Philippe
I like to know what is the problem.The architecture SPARC of my processor Leon3?or something else?

In Orocos, there's atomic operations (mostly assembly code) for each
architecture that it supports. Since SPARC isn't actually a supported
architecture, you will have to modify the orocos library to support SPARC.

Where i find a document explaining the changes?and the result is guaranteed?

To my knowledge, there's no official document that explain how to port
Orocos to a new architecture. However, you will find some useful information
by searching in the forum. What do you mean by "result is guaranteed" ? If
you mean feasible, yes, it's surely feasible but the amount of work to get
there may varies.
Philippe
Yes i mean feasible.Thank
Yes i mean feasible.
Thank you very much.

This is not an orocos-specific question, but rather a general question about
embedded linux system development. Depending on the build system of the
application, there's different ways to cross-compiling an application
(CMake, Autotools). You should start by teaching yourself how to write a
single hello world application for your target system before trying to port
orocos to this architecture. As far as I know, Orocos doesn't actually
support SPARC architecture, so you will have to implement some atomic
operations to make it work (e.g. http://www.orocos.org/node/377).

Is this a "virtual FPGA emulated" processor ? The VIIpro are equiped with 2
(real) PPC405 swimming into the FPGA gates, I am surprised you are not using
them.

I push up this, for having played with the xilinx suite, it's a long way
before setting up a bare metal application.
Are you trying to use Orocos as a bare metal application (I think it doesn't
work but I am not competent to answer) or have you an OS on the board ?
