using DisplayPort RX Subsystem with zynq GTP transciver problem

Jump to solution

Hi,

  I am working with a custom ZYNQ board, and using DisplayPort RX Subsystem v2.1 to receive GPU DP 4K video;

However, the link training was always failed, also dp159 PLL was not locked, and the computer was locked down for a long time during training. GPU can read/write EDID/DPCD, and fpga can config dp159 thru i2c.  the dp159 (package marking is TI 77I AOGO G4)and FPGA got hot. I'm using vivaido 2017.4

Questions:

(a) As PG233 mentioned: Artix®-7 (GTPE2) (Removed in Vivado 2017.4). So consider using zynq GTP, will it be successful to use it as DP sink? Does anybody has tried GTP?

(b) The SDK software makes reference to pg233 zcu102 example , its output menu is not correct:

 

 

Thanks!

Hi @ernesttse,

 

Xilinx does not support DP on Artix-7. You will not get better result in 2016.1 when it was part of the catalog. If you check the IP status it was not in production.

Again, you might want to discuss this with your FAE

Hi @ernesttse,

 

The fact that you can add the Displayport IP from the IP catalog for a XC7Z015 is an miss in the IP. This is an Artix fabric and Xilinx does not support it anymore.

You might want to contact your FAE about this to find the best solution for you.

Hi, I have changed the project under vivado2016.1, it also failed strangely. That verison of PG233 didn't say Zynq GTP not support DP. How to explane these?
