You'll need to give more details for people to be able to help with that - please see How to write your question to maximize your chances to find a solution

PS:

Have you seen this Knowledge Base article:

How to implement inter-processor communication in an STM32H7 using HSEM ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

So look at the error, read it, and fix the issue.

What do you want us to do with this post? No details, just "something doesn't work".

Look at existing examples or show your code and error messages.
