Hi All,


need help on how to explore the pinpong module communication between cores (A9 and M4) with middle ware or applications layer.

Known thing is: now communication is happening between cores (A9 and M4) by RPMsg examples (with the imx_pingpong.ko and freeRTOS pingpong application). 

TODO: by using imx_pingpong.ko (A9 side) how we can expose the pinpong module header-files(rpmsg.h) and APIs to middle ware or application layer( or user level) A9 side. please provide any approach or some examples ( kernel module to user module) if you have already done.

Thanks For your valuable support.
