C6638 SRIO LSU Interrupt Not triggerd

Other Parts Discussed in Thread: SYSBIOS

Hi ,

I am using the TCI6638 Kepler 2 EVM to develop a SRIO driver using the DIO Operation.

With reference to the "SRIO_LpbkDioIsrK2KC66BiosExampleProject", i have configured my SRIO driver.

I am a testing a send/receive functionallity in loopback mode and configuring the LSU completion interrupt.

pSrioSocket->lsuIndex        = LSU_INDEX (gCoreId);

lsuInitParam.intrRequest     = TRUE; // Enabling the LSU completion interrupt

I am able to send/revice the data but the LSU TX interrupt is not received.

Below is the TX completion Interrupt configuration :-

void SRIO_configLSUTxInterrupts()

{  Hwi_Params params;  u32_t eventId;

    /* SRIO DIO Interrupts need to be routed from the CPINTC0 to GEM Event.     *  - We have configured DIO Interrupts to get routed to Interrupt Destination 0     *    (Refer to the CSL_SRIO_RouteLSUInterrupts API configuration in the SRIO Initialization)     *  - We want this System Interrupt to mapped to Host Interrupt 8 */

   /* Disable Interrupt Pacing for INTDST0 */    CSL_SRIO_DisableInterruptPacing (gSrioHandle, 0);

   /* Route LSU0 ICR0 to INTDST0 */    CSL_SRIO_RouteLSUInterrupts (gSrioHandle, 0, 0);

   /* Route LSU0 ICR1 to INTDST0 */    CSL_SRIO_RouteLSUInterrupts (gSrioHandle, 1, 0);

   /* Route LSU0 ICR2 to INTDST0 */    CSL_SRIO_RouteLSUInterrupts (gSrioHandle, 2, 0);

   /* Map the System Interrupt i.e. the Interrupt Destination 0 interrupt to the DIO ISR Handler. */    CpIntc_dispatchPlug(CSL_CIC0_SRIO_INTDST0, (CpIntc_FuncPtr)myDioTxCompletionIsr, (UArg)NULL, TRUE);

   /* The configuration is for CPINTC0. We map system interrupt 112 to Host Interrupt 8. */    CpIntc_mapSysIntToHostInt(0, CSL_CIC0_SRIO_INTDST0, 8);

   /* Enable the Host Interrupt. */    CpIntc_enableHostInt(0, 8);

   /* Enable the System Interrupt */    CpIntc_enableSysInt(0, CSL_CIC0_SRIO_INTDST0);

   /* Get the event id associated with the host interrupt. */    eventId = CpIntc_getEventId(8);

    /* Plug the CPINTC Dispatcher. */    EventCombiner_dispatchPlug (eventId, CpIntc_dispatch, 8, TRUE);

}

I have captured the Event registers with refence to the TCI C66x data sheet.(Sorry, I cant paste the screen shot), due security issues)
