about F28377s DMA data translate

Please provide some more detail about the issue and it'll be good if you could share the DMA code.

DMACH5AddrConfig(&AdcaResults[0], &AdcaResultRegs.ADCRESULT0);
DMACH5BurstConfig(0,0,1); // Burst size, src step, dest step
DMACH5TransferConfig(1023, 0, 1); // transfer size, src step, dest step
DMACH5WrapConfig(0,0,0,1);
DMACH5ModeConfig(1,1,0,0,0,0,0,0,1,1);

above of this is about DMA init, sample ADC data, ADC sample rate is 60K，that is every second need to finish 60 times DMA translate, every time translate 1024 datas

Could it be possible that there is delay in restarting the DMA to transfer next set of 1024 data and that causing the missing samples? Did you try reducing the sampling rate to see if that fixes the issue?
