Since pru_rpmsg_send/receive() don't exist in the mainline kernel you will have
to be more specific... What TI examples are you referring to?  Where can we find
them? 

There are other rpmsg_sendxyz() functions that allow you to send messages to
different addresses[1].  Given the amount of information, I'm afraid there isn't
much else I can add at this time.
