LogiCORE Video PHY Controller, Software Driver v1.1 - Why do I see intermittent training problems, or have trouble with training more than one lane?

Description

Why do I see intermittent training problems, or have trouble with training more than one lane?

Solution

This is a known issue where training fails intermittently or the link only trains one lane.

This is due to an issue in the Video PHY Controller that caused it to only look at the PLL lock for one of the DisplayPort GT lanes.

This issue is resolved in the Video PHY Controller, Software Driver v1.2 in Vivado 2016.3 and later.

Note: Vivado 2016.2 users should see (Xilinx Answer 67924) for a patch.
