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.
