S32K322 dual core best configuration

[francescovico]

Hello,

I'm starting a new project using S32K322.

I would like use core 0 to manage application and core 1 to manage auxiliary functions like CCP communication.

Which is best solution to minimize core 0 occupation?

To send on CCP ram variables (managed by core 0) using core 1 the best solution it's use sharable RAM ?

It's necessary use IPCF driver to avoid conflict?

There are same code example?

Regards, Francesco.

Hello Francesco,

This is all application-dependant.

Refer to these examples:

https://community.nxp.com/t5/S32K/S32K324-Multi-Core-Example-Project-based-on-Whiteboard/m-p/1515429

The example were created with RTD 2.0.0, I would recommend that you install a new S32DS IDE instance for RTD 2.0.0 so that you can open the .mex configurator without any issues.

IPCF is not necessary, S32K322 has HW SEMA42 module - this semaphore is managed by the RM MCAL driver.

Configure an SRAM region as shareable in MPU and enable access to the region from both cores in XRDC.

Regards,

Daniel
