I am trying to get A55 and M7 Core communicating using Zephyr RTOS. I am currently using iMX95LPDDR5-EVK. A core is currently running Linux kernel whose image was generated using yocto.
please try below IPC demo, This demo demonstrates inter-processor communication (IPC) between Linux and Zephyr using OpenAMP, Remoteproc, and RPMsg. The openamp_rsc_table sample uses a resource table to define shared memory and communication channels.
