Problem with IPC on STM32H747I-DISCO

[Nikbia]

Good morning everyone, I have been trying for two days now to perform a communication between the two cores of STM32H747I-DISCO. Being my first time to try my hand at dual core Processors I decided to start from tutorials:
- https://www.youtube.com/watch?v=MLcULDnF5ic
- https://www.youtube.com/watch?v=miUzjoe3rAo&t=561s (Also the precendent videos

Although I followed these tutorials step by step (without even changing the names to the variables) I could not get it to work at all.

I then also tried with the "PingPong" example directly from STMCubeIDE but with both RTOS and bareMetal versions it didn't work...

The only thing I can think of is that maybe I need to move some jumpers on the board or something....

Thanks in advance to everyone

P.S.
FW H7 Version 1.12.1
STMCubeIDE Version 1.18.0
STMCubeMX Version 6.13.0

Hello @Nikbia,

Please check the OpenAMP applications available in the STM32CubeH7 firmware package. Below is the link to download the package: STM32CubeH7.

Two OpenAMP applications are available for the STM32H747I-DISCO board and run without any hardware configuration (located in Projects\STM32H747I-DISCO\Applications\OpenAMP).

Please refer to the readme.txt file available within each project for technical details.

With Regards,

Anis

After creating a new Workspace and a new project (As you said from the OpenAMP_PingPong example) It worked. 
Now I'm comparing the different tutorial on YT with the content of the example project but unluckly there's no .ioc file for the example...

Still I will try to create a running version using this example as reference and I will let you know.

Hi @Nikbia ,

I think this video tutorial is very helpful for understanding how OpenAMP is used with FreeRTOS. I recommend checking it out:
The BEST OpenAMP project implementation on STM32H747 with TouchGFX analogy clock

Thanks for the invise. I looked it up but it doesn't do much different from the other videos and i thinks that the implementation with TouchGFX and also the RTC makes it even more confunsing (Due to it's "Special" Clock setup).

Anyways thank you for your help ;) .
