Hello @RMcCa 

I am working on the same area where i want to write variable in shared memory of SRAM4 via M4 and to read from M7. 

I have gone through your post Best/easiest way to share data between cores in ST... - STMicroelectronics Community

Could you please let me know how to do sharing and writing reading variable in STM32

Thanks in advance

    Hello @Nsg1987,

    Thank you for highlighting a frequent topic/question. Here is an example developed by our colleague in which you can test Inter-CPU asynchronous communication. However, I guess we cannot judge if this is the best or easiest way to share data between two cores.

    Hope this helps!

    Generating a duplicate topics for the same issue is spamming. Why are you spamming?

    An you have already received all the details in your previous topic:

    That link was in the topic, which he said he did read, and it was also recently already given to him specifically and the reaction was: "Could you share any other way..." Beginners cannot do everything - one has to learn things.
