Hi,

Linux RPMsg and M4 OpenAMP libraries uses interrupts. See https://wiki.st.com/stm32mpu/wiki/Coprocessor_management_overview .

Ready made examples are provided in Starter Package.

E.g. On the board console, please view README in  /usr/local/Cube-M4-examples/STM32MP157C-DK2/Applications/OpenAMP/OpenAMP_TTY_echo folder.

I guess examples should run on DK1 too.

Sources of examples are in Developer Package. See for instance https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-M4/Modify,_rebuild_and_reload_a_firmware .
