Forum Post: RE: Errors in EDMA Data Transfer

Hello Chad,

Can you explain the meaning of parameter of CSL_Edma3ParamSetup. I don't know what it is use to do in the follow code:

    CSL_Edma3ParamSetup    myParamSetup;
    
    myParamSetup.srcAddr     = (Uint32)srcAddr;
    myParamSetup.aCntbCnt    = CSL_EDMA3_CNT_MAKE(4,512);//1.what's the meaning of 4 and 512?
    myParamSetup.dstAddr     = (Uint32)destAddr;
    myParamSetup.srcDstBidx  = CSL_EDMA3_BIDX_MAKE(4,4);//2.what's the meaning of 4 and 4?
    myParamSetup.linkBcntrld = CSL_EDMA3_LINKBCNTRLD_MAKE(0xFFFF,0);
    myParamSetup.srcDstCidx  = CSL_EDMA3_CIDX_MAKE(0,1);
    myParamSetup.cCnt        = 1;//3.what's the meaning of 1?

Thank you!

Regards,

Jack
