Hi,

My customer is interested in Message Manager module, which is explained in Technical Reference Manual. It looks like HW queue for messaging between A15, C66 and PRU.

So the questions are:
1. Do you have any example code for this module ? I found the similar question here but it did not answer to the question:

2. What is the easiest way for messaging among the cores on K2G ? I know TI provides IPC framework for TI RTOS and Linux use case, but the problem is they would use 3rd party OS on A15.

Best Regards,
NK

See if this link helps:

The examples about QMSS are available in latest TI RTOS SDK:

Hi Yordan,

Thanks for the reply, but my understanding is QMSS is the part of multicore navigator especially for K2H/E/L or KeyStoneI devices and Message Manager looked different from that. Is Message Manager same with QMSS you suggested here ?

Hi,

Sorry, yes this is different of course. My mistake.

No, there are no examples for the message manager for now.

Available interprocessor communication is IPC & MPM, and as seen from the TRM Message manager is part of IPC, both can be found in the RTOS Software developers guide:
