volatile int32_t i32Count, status = 0;

hMcaspDev2 = NULL;

/* 1. EDMA Initializations */
EDMA3_DRV_Result edmaResult = 0;

/* Enable all McASP events */
sampleEdma3GblCfgParams[0].dmaChannelHwEvtMap[0] |= 0xFFFFu;

hEdma_0 = edma3init(0, &edmaResult); <----- here error

And the following error occurs.
