Understanding and mastering inter-processor communication on STM32MP
In modern embedded systems, it is common to find multiple processor cores (CPUs) working together, each potentially running a different operating system — for example, Linux on a Cortex-A core and an RTOS such as FreeRTOS on a Cortex-M.
Communication between these cores is essential, but there is no single standard to achieve this. OpenAMP, with its RPMsg and RemoteProc components, provides a flexible and widely adopted solution for intercommunication between Linux and RTOS or bare-metal systems.
