Shared Memory in STM32MP257F-EV1 Evaluation Board

Amruta_Dixit · ‎2026-04-17

Hi,

I am working on STM32MP257F-EV1 Evaluation Board. I want to use shared memory (like DDR) between M33 and A35 cores. M33 should write data samples collected form peripherals in shared memory array and A35 should read this memory array to process it further. How to achieve this?
