LogiCORE DisplayPort v6.1 (Rev. 1) - Why do I see training Lost interrupts after training is done and while the Video is Running in the RX core?

Description

After the training is done and the video has started transmitting, the DisplayPort RX gives training Lost interrupts after running for a random amount of time (between 1 minute to 6-7 hours).

There is no issue with the video output. How can this be corrected?

Solution

This is a known issue in the Vivado 2015.4 DisplayPort v6.1 (Rev. 1) IP.

This issue is resolved in Vivado 2016.1.

Please see (Xilinx Answer 66301) for a patch for the DisplayPort v6.1 (Rev. 1) in Vivado 2015.4.
