IPC Notify Event not responding

Hi , 

MCSDK version : 2.2.1.03

IPC Version: ipc_1_25_03_15

Bios Version : bios_6_35_04_50 

XDC version : xdctools_3_25_03_72 

We are trying out interrupt based Message_get() .  Since Message_put() and Message_get() uses signal() and wait() functions which are more like polling . 

So we thought of using notify to send an interrupt as soon as the put happens to the remote proc . But unfortunately the code is not calling the callback function.

In ROV we saw Notify event registration is successful for both the cores. 

Core 0 : Puts the message and send the event 

Core1:  Is in indefinite run state .

Core 0 code snippet : 

               status = MessageQ_put(remoteQueueId, msgTx);

               if (status < 0) {
                  System_abort("MessageQ_put had a failure/error\n");
               }
               System_printf("Msg Core1 put \n");
               status = Notify_sendEvent(nextProcId, LINEID, eventId, NULL, TRUE);

core 1 code snippet : 

attachAll(Num_Processor) ;

    status = Notify_registerEventSingle(nextProcId, LINEID, eventId,(Notify_FnNotifyCbck)Core0_Interrupt,
                                        NULL);

void Core0_Interrupt(UInt16 procId, UInt16 lineId,UInt32 eventId, UArg arg, UInt32 payload)
{


	          int status ;
			 status = MessageQ_get(messageQ, &msgRX, MessageQ_FOREVER);
		     if (status < 0)
		     {
			  // System_abort("This should not happen since timeout is forever\n");
			 }
		     core1msg = (Core1Struct*)msgRX;
		    // System_printf("Msg Core1 Got :: %d\n" ,core1msg->test_val1);
			 status = MessageQ_free(msgRX);
	         if(status == MessageQ_E_FAIL )
			 {
			    // System_printf("Msg free failed\n");
			 }



}

#   We tried semaphore_pend and post to handle the interrupt flow : but both core was getting into an indefinite run state (Deadlock) .

PS : WIthout the notify functionality the code was working fine with MessageQ_get in BLOCKING mode. 

1# Can MessageQ_get() can be called inside the Callback function ?

2# Is default value for EventId and LineId is 0 or any values can be assigned ?
