How to set up EDMA3 with BFIFO

Hi,

I am working on to set up OMAP-L138 MCBSP1 to working with a telecom codec, that codec working on 2.048MHZ PCM clock, 8KHZ SYNC, each channel is 8 bits, totoal 32 channels for one frame. i want to set EDMA3 and BFIFO to working as following requires

1. continue to send and receive pcm

2. PING-PONG buffer serviced

3. SYNCDIM is AB type

4. when received in 8 frames(that is 8*(32 * 8bits)) and the EDMA report a interrupt and send to other program to process

here is my Edma3ccParam Setting

BFIFO define as following

----------------------------------------------

CSL_FINST(hMcbspFifo->WFIFOCTL, BFIFO_WFIFOCTL_WNUMDMA, 1WORDS);
CSL_FINS(hMcbspFifo->WFIFOCTL, BFIFO_WFIFOCTL_WNUMEVT,
NUM_ELEMENTS_PER_DMA_EVENT);
CSL_FINST(hMcbspFifo->WFIFOCTL, BFIFO_WFIFOCTL_WENA, ENABLED);

CSL_FINST(hMcbspFifo->RFIFOCTL, BFIFO_RFIFOCTL_RNUMDMA, 1WORDS);
CSL_FINS(hMcbspFifo->RFIFOCTL, BFIFO_RFIFOCTL_RNUMEVT,
NUM_ELEMENTS_PER_DMA_EVENT);
CSL_FINST(hMcbspFifo->RFIFOCTL, BFIFO_RFIFOCTL_RENA, ENABLED);

while (CSL_FEXT(hMcbspFifo->WFIFOSTS, BFIFO_WFIFOSTS_WLVL) == 0)
;

DELAY_MICROSEC(5);

CSL_FINST(hMcbsp->SPCR, MCBSP_SPCR_XRST, ENABLE);

-----------------------------

and the WFIFO - RFIFO status is (printf("WFIFOSTS-RFIFOSTS  %x-%x\n", hMcbsp1Fifo->WFIFOSTS, hMcbsp1Fifo->RFIFOSTS);)

[C674X_0] Enter mcbsp1
[C674X_0] WFIFOSTS-RFIFOSTS 40-0
[C674X_0] WFIFOSTS-RFIFOSTS 3f-0
[C674X_0] WFIFOSTS-RFIFOSTS 3f-1

[C674X_0] WFIFOSTS-RFIFOSTS 3f-1
[C674X_0] WFIFOSTS-RFIFOSTS 3f-1

------------------------------------------

but i can not get any output from DX port, please help to figure out where is wrong of setting. btw, the SYNC and PCM CLOCK is working as expected.

Thank you
