S32k322 Messaging Unit Driver

[slawomir-bb]

Hello,

If I understood correctly from the S32k3xx RM, there is a possibility tu utilize MU_2 for application purposes for inter-processor communication (i.e. between cores). Unfortunatelly I cannot find any code related to MU usage in RTM. I know, there is a IPCF lib, which seems to be a software implementation of message queue, which uses core-to-core IRQs. 

I would like to use that HW message queue to send very small payload between cores.

Are there any drivers and examples related to it available?

Best Regards,
Slawomir

Hello @Senlent ,
thank you for the reply. I have IPCF installed. But I'm interested in direct use of MU HW queues, without extended software implementation which IPCF provides. If IPCF package provides such driver for MU, could you please show me which entry from the driver list I have to add to my config?

Hi@slawomir-bb

You can check out the IPCF we provide, which should be based on the MU module.

And,there is no separate MU driver available for your reference.
