As described already in another post (treating of another problem),I trying to port Microzed ref design using Python and HDMI on SVDK running on Vivado 2015.2 instead of 2014.4.
I now get an image from the Sensor of HDMI but it contains artifacts. When using test pattern generator I don't get any artifacts. Those artifact are vertical repetition every centimeters (on my 22" screen) of around 6 to 8 pixels width random pixel colors(most being white).
You can see pictures on below link (Xilinx forum):
There is I think two potential rootcause:
1/Internally generated serdes clock inside Python block is not working properly on my design.
Unfortunately, it was not able to solve this problem.
2/ Registers value set within the IP core for Python are not the recommended value inside Python datasheet. What is strange is that I don't think that initial ref design running on Microzed in Vivado 2014.4 shows any problem with those values.
Thanks for your help.
