DDR到SL2的EDMA数据搬移

工程师好，我现在利用调用例子函数的EDMA搬移就能搬移成功，我把接口去掉直接调用内部函数搬移一直没更新，提示EDMA3_DRV_enableTransfer Failed, error code:-139错误代码。为了简洁我把srcBIdx这几个参数都先设置为64，我的程序如下：

EDMA3_DRV_PaRAMRegs paramSet;

EDMA3_DRV_Handle hEdma;

unsigned int chId0= 0;

unsigned int tcc0= 0;

unsigned int edmaInstance = 0;

EDMA3_DRV_Result edmaResult = EDMA3_DRV_SOK;

//EDMA3_DRV_Result result = EDMA3_DRV_SOK;,

hEdma = edma3init(edmaInstance, &edmaResult);

/* Setup for Channel 0*/

tcc0 = EDMA3_DRV_TCC_ANY;

chId0= EDMA3_DRV_DMA_CHANNEL_ANY;

/***************/

// Request any DMA channel and any TCC

EDMA3_DRV_requestChannel (hEdma, &chId0, &tcc0, (EDMA3_RM_EventQueue)0, NULL, NULL);

   paramSet.srcBIdx   = 64;

   paramSet.destBIdx   = 64;

   paramSet.srcCIdx   = 64;

   paramSet.destCIdx   = 64;

   // For AB-synchronized transfers, BCNTRLD is not used.

   paramSet.bCntReload = 64;

   paramSet.linkAddr   = 0xFFFFu;

   // Src & Dest are in INCR modes

   paramSet.opt &= 0xFFFFFFFCu;

   // Program the TCC

   paramSet.opt |= ((tcc0 << OPT_TCC_SHIFT) & OPT_TCC_MASK);

   // Enable Intermediate & Final transfer completion interrupt

   paramSet.opt |= (1 << OPT_ITCINTEN_SHIFT);

   paramSet.opt |= (1 << OPT_TCINTEN_SHIFT);

   paramSet.opt |= (1 << OPT_SYNCDIM_SHIFT);

    /****************************************/

   EDMA3_DRV_setPaRAM(hEdma, chId0, &paramSet);

    srcAddr = (Uint32)pMatC     ;

    dstAddr = (Uint32)pBufPackCL2 ;

       pParamSet->srcAddr   = srcAddr;

    pParamSet->destAddr   = dstAddr;

    /* Now, write the PaRAM Set. */

    EDMA3_DRV_setPaRAM(hEdma, chId, pParamSet);

    EDMA3_DRV_setSrcParams (hEdma, chId, srcAddr, EDMA3_DRV_ADDR_MODE_INCR, EDMA3_DRV_W8BIT);

    EDMA3_DRV_setDestParams(hEdma, chId, dstAddr, EDMA3_DRV_ADDR_MODE_INCR, EDMA3_DRV_W8BIT);

       EDMA3_DRV_Result result = EDMA3_DRV_SOK;

    // trigger DMA transfer

    result = EDMA3_DRV_enableTransfer (hEdma, chId, EDMA3_DRV_TRIG_MODE_MANUAL);

    if (result != EDMA3_DRV_SOK)

       printf ("edma3_test: EDMA3_DRV_enableTransfer Failed, error code: %d\r\n", result);
