Hi all
We are seeing some errors where our ADC16x250 cards don’t seem to be completing
SERDES calibration successfully when programmed (using the adc16_init.rb
script).
Running the adc16_status.rb script we see errors like this:
rofl1: Design built for ROACH2 rev2 with 8 ADCs (ZDOK rev2)
Hi, Danny,
If you have its dependencies installed, the adc16_plot_taps.rb script can be
useful for showing the deskew stuff. The sync errors seem really strange.
What is the ADC clock frequency? Have you tried swapping ADC clock cables
between a “good” ROACH2 and a “bad/marginal” ROACH2?
