That seems ... odd. What's the point of having a > variable src and dst if they are effectively hardwired to a single > communication channel? 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. Thanks, Mathieu [1]. https://elixir.bootlin.com/linux/latest/source/include/linux/rpmsg.h#L125 > > Thanks.
