TMS320C6713B: EDMA 1D transfer with frames

Part Number: TMS320C6713B

Hi
I am doing maintenance on some old code running on TMS320C6713, and I have some EDMA probles. I want to copy every second value from source to dest.
int source[5][65536];
int dest[5][32768];
To do this one need to use “1D” transfer since the element index is stepped by a value different from 1, and since the arrays are big one need to divide them into frames, and this is where I run into troubles.
I want to start the DMA transfer, and then I check the CIPR bit at each timer interrupt to see when the transfer is finished.

I have made a test case with smaller arrays:

int mySource[4][16];
int myDest[4][8];

EDMA_Handle handle;
EDMA_Config config;
short tcc;
EDMA_Handle hMyReload;

EDMA_Config myConfig = {
   EDMA_OPT_RMK(
      EDMA_OPT_PRI_LOW,
      EDMA_OPT_ESIZE_32BIT,
      EDMA_OPT_2DS_NO,
      EDMA_OPT_SUM_IDX,
      EDMA_OPT_2DD_NO,
      EDMA_OPT_DUM_INC,
      EDMA_OPT_TCINT_YES,
      EDMA_OPT_TCC_OF(0),  //Reserve TCC later
      EDMA_OPT_LINK_YES,
      EDMA_OPT_FS_YES
      ),
   
   EDMA_SRC_OF(&mySource[0]),
   EDMA_CNT_OF(0x00030008),  // 0x0003=4 frames, 0x0008=Elements to copy in one frame 
   EDMA_DST_OF(&myDest[0]),   
   EDMA_IDX_OF(0x00400008),  // 0x0040 bytes offset to next frame, 0x0008=Element index (in bytes)
   EDMA_RLD_OF(0)}

   
//---   
   //EDMA setup
   config = myConfig;
   handle = EDMA_open(EDMA_CHA_ANY, EDMA_OPEN_RESET);  //Open any free local_id
   EDMA_config(handle, &config);  
   tcc = EDMA_intAlloc(-1); ////Reserve a TCC number (0 to 15), -1=any free CIPR/TCC
   config.opt |= EDMA_FMK(OPT, TCC, tcc);  //Update options
   EDMA_intDisable(tcc); //We want to access irq registers like CIRP, but not generate a CPU interrupt since we will poll.   
   EDMA_config(handle, &config);    //Update config
   
   hMyReload = EDMA_allocTable(-1);  //Allocate reload 
   EDMA_config(hMyReload, &config);  //Config reload
   EDMA_link(handle , hMyReload);    //Link the handlers together
   EDMA_link(hMyReload , hMyReload);

//--   

The problenm I have with this code is that I have to run

EDMA_setChannel(handle)

four times (i.e. same as the frame size) before the entire copy process i done and the CIPR bit is set.

How can I kick the EDMA transfer to run all frames in one go?
