IPC Events along with Message_Q

Other Parts Discussed in Thread: TMS320C6678

Hi

I want to implement a Message_Q on my design using  TMS320C6678 EVM along with IPC event (using IPCGRn), so i run first the MessageQ (single image for all cores) example from IPC and I/O examples for C6678 and it works great, but when i added an HWI ISR to handle the IPC events from the other cores every time that MesssgeQ_put() was called (I assumed that this was the reason) the HWI for the IPC was invoked in the destination core with different messages (0, 1 or 2).

So, my questions are:

  • 1. Why is it happening?
  • 2. If this is the correct behavior, is there any way to knowwhich messages could be generated(or maybe all kind of messages could be generated)?
  • 3. Is there any way to use Message_Q along with IPC events?

 I'm using:

 CCS V5.0.3.00023

Sys/bios 6.32.02.39

IPC 1.23.02.27

XDC 3.22.01.21

           

Thanks
