I am using PYNQ with ZCU111 RFSOC board. I have probed the design hardware using ILA’s and I can see that the RF data converter has ADC and DAC clock out active, indicating it has all the clocks it needs.
None of the reset pins are being asserted and the adc_status[3:0] bus indicates 0xF . However when I monitor the output of the master axis busses driving the ADC digital output, I see there is no activity. The Axis interface tready and tvalid flags are also asserted.
The lack of activity from ADC must surely mean it is being held off somehow. Doe sanyone have a sample PYNQ Python file that wakes up the ADC? attached is one I have tried to use.
