I have a simply question. I want to know the different ways some cores can communicate with each other. I have the imx6sx platform with FreeRTOS and Linux. In order to communicate both cores I think there are three ways: rpmsg, MU and shared memory. Is that correct?
I understand that rpmsg use blocking function, therefore, it is not the besto obtion for Real Time applications. Besides, I can not found examples using MU, does NXP provide any example?
