RPMsg bypass

On the imx8mm is it possible to use shared memory between the A53s (Linux) and M4 (RTOS) without going through RPMsg?  I don't see any notes stating that it's not possible, but also no examples of doing it without RPMsg.

TIA

Hi greg.edwards@harman.com ,

You can implement the shared memory between A53 and M4 on your own by sharing the DDR between them. However, RPMSG does the same. So, I would suggest rather than implementing it, you use the supported RPMSG.
