    I have tested the MCBSP  and EDMA  with ping pong the example provided is not using MCBSP interrupt
    which is important for as.
    can you please provide with MCBSP interrupt
    since we are reusing code chip 6424.

    as i understand, the event number for the mcbsp is found on the secondary event table 
    Table 6-27. CIC0 Event Inputs (Secondary Interrupts for C66x CorePacs) on page  109 
    in the file tms320c6657.pdf.
    in the file sprugw4a i found example, but in the linking process it fails on missing function 
    definition like CSL_intcGlobalEnable, CSL_intcGlobalNmiEnable, CSL_intcHwControl,
    CSL_intcInit, CSL_intcIOpen, CSL_intcPlugEventHandler
    this functions are define in the "ti/csl/src/intc/csl_intc.h" but the code is missing
    for sum of the function

    Doron,

    I am able to find both the declarations and definitions too.

    For example, for the function, "CSL_intcPlugEventHandler", it is given in csl_intcPlugEventHandler.c located at 

    C:\ti\pdk_c665x_2_0_16\packages\ti\csl\src\intc\

     

    CSL_Status CSL_intcPlugEventHandler (
    CSL_IntcHandle                        hIntc,
    const CSL_IntcEventHandlerRecord     *eventHandlerRecord
)
{
    volatile Uint16  i;
    CSL_Status status = (CSL_Status)CSL_ESYS_FAIL;

    CSL_dint();

    /* Search for free entry and plug in handler */
    
    for (i = 0; i < CSL_intcNumEvents; i++) {
        if (CSL_intcEventHandlerRecord_p[i].handler == CSL_INTC_EVTHANDLER_NONE){
            /* Plug in Handler */
            CSL_intcEventHandlerRecord_p[i].handler =
                eventHandlerRecord->handler;
            CSL_intcEventHandlerRecord_p[i].arg =
                eventHandlerRecord->arg;    
            /* Establish mapping */
            CSL_intcEventOffsetMap[hIntc->eventId] = (Int8)i;
            status = CSL_SOK;
            break;          
        }
    
    }
    CSL_rint();
    
    return status;
}

    Regards
