ZCU102 DP PHY setting failed (suspect of failed board)
We have a ZCU102 and used it for Displayport application. Things have been working fine and I was able to get DP output (vivado 2019.1). Later, the board was used to run some GPIO test. Now I re-run DP project, the DP TX PHY setting has failed. DP AUX read also failed. I used ZCU102 system control GUI to read voltage level, they are good. I also re-set frequency. Nothing helped the DP interface. I suspect the board is damaged during GPIO test but not sure, so I wonder if there's any board interface test I can run to identify the issue.
