Great, this is what we've been doing with davinci too.

What exactly are you looking for ? RTOS or Linux side ?

On the Linux side, you can just make the rpmsg sample work (it's part
of the rpmsg patch set). For the RTOS side, feel free to just take our
code (it's BSD licensed and hosted on github) and adapt it to your
environment.
