STM32H747 Dual Core Communication

Hello;

With STM32H747, I am trying to communicate with both cores.

For example;

To be able to read a variable in CM4 in the CM7 core. Depending on the state of this variable I read, running certain functions in CM7, etc.

I couldn't find a document or example of how to do it.

Place data in a structure, at the same address/location which both cores can access, and use HSEM to signal​.

See block diagram or memory matrix to determine memory both can see, and address within each cores memory view.​
