Memory Protection for Dual core S32k322 Controller

Hi Team,

Could you please share any example project or reference material demonstrating the use of MPU (Memory Protection Unit) and PPU (Peripheral Protection Unit) for a dual-core setup on the S32K322 controller?

BR,

The S32K322 does not include a module named 'PPU'. If you're referring to peripheral access protection, this is managed through the XRDC (Extended Resource Domain Controller), which allows you to configure access rights for peripherals and memory regions across the dual-core setup. Let us know if you were referring to a different concept or platform.

Example code you may find within RTD:

RM_Example.. shows also XRDC setup example, Platform_.. contains MPU setup example

Hi @davidtosenovjan ,

Thank you for the reference to the MPU example. However, I couldn't find an MPU example specifically for a dual-core setup. Could you please assist me with this?

BR,

There is no such example. Basically as multi-core projects are done separately for each core, and MPU is peripheral of the core, you would use two such projects. Configuration is however application specific.
