data sharing between the cores

[Srinath_03]

Hi,

I'm using STM32H7 dual core, where the data has to be shared between the cores, so im having totally 21 variables totally 76 bytes, thought of do it like a structure, so where to place the structure exactly for this data sharing. so, this structure should be placed in any linker file of one of the cores or where?

if so, thus we have to keep the structure in both the core or what

which method is a fastest wat to share the data, like a ring buffer, HSEM.

if we use HSEM, we can use that structure or access outside, before calling the HSEM TAKE, or structure values should be assigned only inside after the HSEM TAKEOVER.

 

 

regards,

srinath
