Hi,
There are different modules inside the S32G platform that may help to communicate the A53 cluster with an M7 core (either internally or externally). The common recommendation for this application is to use the "Inter-Platform Communication Framework" (IPCF), which uses an internal IRQ and shared memory between the different cores.
This framework should be available in the S32G2 product page (link: S32G2 Safe and Secure Vehicle Network Processor | NXP Semiconductors) under the "Software" section by the name of "Automotive Software Package Manager".
IPCF is not available as a standalone solution, it needs a previous package (Real-Time Drivers) for it to work. This package manager should give you the IPCF package as well as the corresponding RTD needed, given you select it for download. Also, the provided Linux BSP version should also have the corresponding IPCF needed to run the available examples.
Please, let us know if this information was helpful or not.
