EDMA problem

Hi all

I am working with the C6A8168 EVB, and I am investigating about the EDMA usage.

So I have written a DSP demo application which move a block memory from one buffer to another one.

The function I have written is the follow:

void dma_int_copy(int *source, int *destination, int size, int dma_ch, int tcc_code)

{

    edma3Regs = (CSL_Edma3ccRegs *) REGS_BASE;

    // Set channel to Region 1 DSP.

    edma3Regs->DRA[1].DRAE = 1 << dma_ch;

    edma3Regs->DCHMAP[dma_ch] = (PARAM_BASE + (dma_ch * 0x20));

    myParamSetup_base = (CSL_Edma3ParamSetup *) (PARAM_BASE + (dma_ch * 0x20)) ;

    myParamSetup_base->option = CSL_EDMA3_OPT_MAKE(CSL_EDMA3_ITCCH_DIS, \

                                              CSL_EDMA3_TCCH_DIS, \

                                              CSL_EDMA3_ITCINT_DIS, \

                                              CSL_EDMA3_TCINT_EN,\

                                              tcc_code,                        // TCC_CODE

                                              CSL_EDMA3_TCC_NORMAL,\

                                              CSL_EDMA3_FIFOWIDTH_NONE, \

                                              CSL_EDMA3_STATIC_DIS, \

                                              CSL_EDMA3_SYNC_AB, \

                                              CSL_EDMA3_ADDRMODE_INCR, \

                                              CSL_EDMA3_ADDRMODE_INCR);

    myParamSetup_base->srcAddr         = (Uint32) source;

    myParamSetup_base->dstAddr         = (Uint32) destination;

    myParamSetup_base->aCntbCnt     = CSL_EDMA3_CNT_MAKE(4, size);

    myParamSetup_base->srcDstBidx     = CSL_EDMA3_BIDX_MAKE(4,4);

    myParamSetup_base->linkBcntrld     = 0;

    myParamSetup_base->srcDstCidx = CSL_EDMA3_CIDX_MAKE(0,0);

    myParamSetup_base->cCnt = 1;

    edma3Regs->SHADOW[1].ICR |= (1 << tcc_code);    // clear the interrupt

    edma3Regs->SHADOW[1].ESR |= (1 << dma_ch);        // trigger the dma channel

    while( (edma3Regs->SHADOW[1].IPR & (1 << tcc_code) ) == 0);    // poll for xfer completion

}

called by the follow:

                int source[SIZE], destination[SIZE],i;

    for(i=0;i<SIZE;i++)

    {

        source[i] = i;

        destination[i] = 0;

    }

    dma_int_copy(source, destination, SIZE, 21, 21);

So I have created a 'typical' SYS/BIOS example project, and I have added the dma_int_copy() function and it works fine.

At this point, I have created a new SYSLINK project, following the steps found in:

http://processors.wiki.ti.com/index.php/Creating_CCS_Project_for_SysLink_samples

This sample, loaded with 'slaveloader_debug' work well.

Now I have added the dma_int_copy() to the sample, but the memory block has not been copied.

Someone could image the problem?

Bye.
