I try to build a rpmsg sample app by following this instruction : https://docs.zephyrproject.org/latest/samples/subsys/ipc/rpmsg_service/README.html
The example repository here: https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/subsys/ipc/rpmsg_service
It seems that the device tree overlay is missing for STM32MP157F-DK2, so I create one
/ {
chosen {
/*
* shared memory reserved for the inter-processor communication
*/
zephyr,ipc_shm = &mcuram2;
zephyr,ipc = &mailbox;
};
mcuram2: mcuram2@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x40000>;
};
It is not working, please advice if the device tree is correct or not? and Is there any relation with Linux device tree?
thanks
