Hello!

I'm trying to understand the interaction between CA7 and CM4.

I need to acquire some real-time signals in CM4 and show the signal in a display on CA7.

What is the easy way and what is the right way to do this?

​Hello lenonrt(IFSul)

I would suggest to read the STM32MP1 Coprocessor management overview to understand the interaction between CA7 and CM4:

https://wiki.st.com/stm32mpu/wiki/Coprocessor_management_overview

From there you can download the STM32CubeMP1 package: https://www.st.com/en/embedded-software/stm32cubemp1.html in which you can find some Application examples featuring the inter processor communication via OpenAmp. Also you will find a comprehensive set of examples for developping your real time application in CM4 domain.

Best Regards,

Olivier
