I need help using OpenAMP

[motaz9898]

Inquiry about the possibility of opening multiple endpoints to facilitate communication between M7 and M4, so that each specific message triggers a specific response.

Hello @motaz9898 ,

Please have a look at this article which shows how to implement inter-processor communication between CM7 and CM4 cores: How to implement inter-processor communication in ... - STMicroelectronics Community

There is an OpenAMP_PingPong example which is available in STM32CubeH7 MCU package.

I recommend you have a look to this video Inter-process Communication via OpenAMP.

Hope this helped you!

My issue is that when I add the OpenAMP initialization instructions to the task, the processor freezes.

if (MX_OPENAMP_Init(RPMSG_MASTER, new_service_cb)!= HAL_OK);
