Hello, i have read the document but still confused. Can i send some data bytes from cm7 to cm4 using IPC?

Hello,

Indeed you can share data between the two cores. You can also refer to the examples provided by STM32CubeH7 package under the path \Projects\STM32H745I-DISCO\Applications\OpenAMP

Also refer to the oscilloscope demo X-CUBE-H7DC-APP.
