I'm using No-OS driver of ad9364. I set the sampling rate to 33.55MHz, and the custom waveform is 256 points in length. The DAC is set to DMA mode so that it should produce continuous waveform. However, when I took a loop-back test and measure what the ADC receives it seems to be time-sloted with about 8000 samples (approximately 0.25ms long).
I noticed that there was a similar situation discontinuous custom waveform, are they the same issue?
Thanks in advance.
