I have few queries for zephyOS support for STM32H757

Does ZephyOS support symmetric multipoint processing on cortex M7 and M4 cores.
Can I only execute ZephyOS on M7 and baremetal application on M4 core.
Does ZephyOS support OpenAMP for STM32H757 between cortex M7 and M4
If OpenAMP is supported for STM32H757 via ZephyOS , is it possible to communicate between ZephyOS on M7 and baremetal OpenAMP on M4 ?

Regards,
Sarfaraz

Hi Sarfaraz,

No, Zephyr OS does not support SMP
Yes you can. Take a look at this board: https://github.com/zephyrproject-rtos/zephyr/blob/main/boards/st/stm32h757i_eval. also take a loot at its documentation, you might find this useful: https://docs.zephyrproject.org/latest/boards/st/stm32h757i_eval/doc/index.html
Yes again. see sample: https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/subsys/ipc/openamp. Take a look at esp32_devkitc_procpu and esp32_devkitc_appcpu for example
It should in theory but I don't have the hardware to confirm.
