Both side will be great. Rtos is freertos.

You mean that server_sample and rpmsg_omx right? I have also found rpmsg-omx demo application. What I am missing is how to probe rpmsg bus. Do you have any working example?
Communication between cpus is done through swirqs. I have test sending it from linux to rtos.
