The board is based on STMicroelectronics STM32MP157 processor based on a dual Cortex-A7 core and a Cortex-M4 core.
STM32MP1 family support depends on STM32 HAL and OpenAMP for inter-core communication.
This change has been verified with zephyr-philosophers and zephyr-shell sample applications on by loading Zephyr image to Cortex-M4 core from Linux using remoteproc framework.
