AWR1843中数据EDMA搬移丢失求解

       我的EDMA配置设置如下：

      numPingOrPongSamples = obj->numRangeBins * obj->numRxAntennas;
      aCount = numPingOrPongSamples * BYTES_PER_SAMP_1D;

     if (gMrrDSSMCB.subFrameIndx == 2)
    {
        oneD_destinationBindex = (int16_t)aCount;
        oneD_destinationPongAddress = (uint8_t *)(&obj->radarCube[aCount * 2 * obj->numDopplerBins]);
    }
    else if (gMrrDSSMCB.subFrameIndx == 1)
    {
        oneD_destinationBindex = (int16_t)aCount;
        oneD_destinationPongAddress = (uint8_t *)(&obj->radarCube[aCount * obj->numDopplerBins]);
    }
 else
 {
        oneD_destinationBindex = (int16_t)aCount;
        oneD_destinationPongAddress = (uint8_t *)(&obj->radarCube[0]);
 }

/* MMW_EDMA_CH_1D_OUT - Copies from ping FFT output (even chirp indices)  to L3 */
    retVal =
    EDMAutil_configType1(context->edmaHandle[MMW_DATA_PATH_EDMA_INSTANCE],
        (uint8_t *)(SOC_translateAddress((uint32_t)(&obj->fftOut1D[0]),SOC_TranslateAddr_Dir_TO_EDMA,NULL)),
        oneD_destinationPongAddress,
        MMW_EDMA_CH_1D_OUT,
        false,
        MMW_EDMA_CH_1D_OUT_SHADOW,
        aCount,
        obj->numChirpsPerFrame, //bCount
        0, //srcBidx
        oneD_destinationBindex, // //dstBidx
        eventQueue,
        NULL,
        (uintptr_t) obj);

     启动运行后，发现在EDMA数据搬移过程中，只能将一部分数据搬移到我的目标地址oneD_destinationPongAddress中，剩下部分全部为0，如下图所示（numRxAntennas = 4，numRangeBins = 32，numDopplerBins = 64，numTxAntennas = 3, numChirpsPerFrame = 1）：
