I have a simple ZCU111 project which has four ADC and four DAC channels.
Unfortunately I cannot get the ADC to output any data, so I checked the all the clocks, PLLs etc and all are running. I beleive the ADC won’t start up until it is reset.
Then I looked at the pl_resetn0 coming out of the ZYNQ processor, I have this drive an external pin, so I can monitor it.
Unfortunately I can never assert reset .
I can re program the PLLs ADC & DAC tiles etc, but I do not know how to drive this reset pin using PYNQ.
