Message unit in iMX7

[suryapradhan]

Hello,

I am using iMX7D based board & my objective is to communicate between its two processors (Cortex-A7 &  Cortex-M4).

From technical data sheet of iMX7D i got to know that Message Unit(MU) normally does this work.

Is there any default driver for Message Unit [MU] or reference document for communication between two cores.

Thanks & regards

Surya

Hi Surya

seems it is necessary to generate them by building image, use guidelines in

attached Linux Manual.
