DMA_configMode () not working

Thank you  Matthew for your swift response,

Yes, I discovered that but now I am having problem to "RE trigger" the DMA.  it seems to trigger only once. 

I tried to restart as shown below but no luck:

__interrupt void dmaCh1ISR(void)
{
static int PingPong =0;
static int test =0;

PingPong ^=1;
test= test +1;

DMA_startChannel(DMA_CH1_BASE);

return;
}

void initDMA()
{
//
// Refer to dma.c for the descriptions of the following functions.
//

//
//Initialize DMA
//
DMA_initController();

const void *destAddr;
const void *srcAddr;

srcAddr = (const void *)sData;
destAddr = (const void *)rData;

//
// configure DMA CH1
//
DMA_configAddresses(DMA_CH1_BASE, destAddr, srcAddr);
DMA_configBurst(DMA_CH1_BASE,BURST,1,1); // DMA_configBurst(DMA_CH1_BASE,BURST,1,1);
DMA_configTransfer(DMA_CH1_BASE,TRANSFER,0,1); //
DMA_configMode(DMA_CH1_BASE,DMA_TRIGGER_EPWM1SOCA, DMA_CFG_ONESHOT_DISABLE);
DMA_setInterruptMode(DMA_CH1_BASE,DMA_INT_AT_END);
DMA_enableTrigger(DMA_CH1_BASE);
DMA_enableInterrupt(DMA_CH1_BASE);
}

Cheers

Naim,

Can you enable continuous mode in your _configMode funcition call and see if this works.  Your ISR looks correct, the _startChannel should reactivate the DMA, but setting continous mode would show if this is the issue or not.  If this doesn't work, then there is some other setting effecting things.

Best,

Matthew
