Hi @IvyGuo
We have available examples of the Inter-Platform Communication Framework (IPCF). Subsystem that enables applications, running on multiple homogenous or heterogenous processing cores, located on the same chip or different chips, running on different operating systems, to communicate over various transport interfaces.
You can download them from S32K3 Standard Software > Automotive SW - S32K3 - Inter-Platform Communication Framework.
