IMX8MM: RPMsg between A core and M4

I am using a IMX8MM in my project and running android 9 on this. In the project, we plan to have some GPIO function working on M4, and there will be some communications between A core and M4.


I have download the RPMsg-lite sample for reference, but I still have no idea what's the mechanism for avoiding resources overlap on both A core and M4. Is the multicore manager responsible for the resource allocation and monitoring between multiple core? If it is, where can I find the sample code? (I only found RPMsg-lite under the multicore example folder)
