Communication between cores

[imanolallende]

Hello,

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?

Thank you,

Imanol Allende

I uploaded the mx6sx pdf file, you can find the MCC(multi-core communication) part, hope helpful for you.

Are you talking about this file: imx6x muliticore 

Is there any example to use the MU with Linux and FreeRTOS?

I can not find in Linux how to access the MU, I just find the mu.c.

And why does rpmsg use MU functions?
