DMA IP cause Jupyter notebook kernel dying

Support

Hi,

I follow this design: GitHub - strath-sdr/rfsoc_qpsk: PYNQ example of using the RFSoC as a QPSK transceiver.

And I modify rf data converter ip the dac and adc sampling rate to 512MHz, and the interpolate factor and decimate factor to 8x

and I also removed some module in prior design
rfsoc_qpsk_bd.tcl (112.2 KB)

Thanks!

the clock setting is below:

I’m not sure if the setting is causing the error

It can work now, but receive all the noise.
how can i receive the correct data?

What did you do to correct your “DMA channel not started” issue?

I modified the DAC and ADC sampling rate,
but the rx still received noise.
