Dual core communication S32K322

[Stark_]

Hi everyone,

I have started a dual-core project where both Core 0 and Core 1 are enabled. As a test, I have created an incrementing variable on each core.
What is the recommended way to share or transfer this variable data from Core 1 to Core 0 (and vice versa)?
Any examples or best practices using shared RAM would be greatly appreciated.

microcontroller : NXPS32k322

IDE: S32 Design Studio
RTD: v3
Debugger: PEMicro

Thanks!

I would recommend to use Inter-Platform Communication Framework (IPCF)

Examples and trainings are included.

Hi @davidtosenovjan 

According to the demo training, the IPCF Quick Start Guide includes a middleware block and driver, but they are not available in my configuration tool.

configuration as in Demo training

configuration in my project

is there any-other way to share the data between the cores ?

Please refer to UM12479: User Manual for S32K3 IPCF for 5.2 NXP S32 Design Studio Configuration

Hi @db16122 

Without IPCF driver, dual-core can communicate in S32K322?

There are no direct communicated channel between two core physically.

How about add two counter for each M7 core? Once the M7 is running, the counter start to count and you can check the value if it is same or not.

BTW, what is the purpose to check each core status? for safety reason?

Hi @db16122
I started working on a dual-core setup and verified that Core 0 and Core 1 are running by using counters. However, my main question is: how do I pass data from Core 1 to Core 0 and vice versa? Do you have an example related to data sharing between cores?
