Example of OpenAMP send message from core M4 to M7 (Nucleo H745ZI)

Hello everyone,

I am using Nucleo H745ZI dual core and I want to communicate intercore by OpenAMP.

The ST only giving example send message from core M7 to M4. But I want to send message from core M4 to M7, I tried follow the OpenAMP flowchart but not working.

Do anyone has the example of OpenAMP send message from M4 to M7?

EDIT:

Indeed, it does (from the data brief:(
