help on how to explore the pinpong module APIs to communicate between cores (A9 and M4) with( kernel module to user module) middle ware or applications layer

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.

Regards

-Anil

Hi,

in case you are looking for exposing RPMSG endpoint to Linux userspace please look at following GitHUB project GitHub - NXPmicro/rpmsg-sysfs: Linux sysfs interface for RPMsg      .
