In DisplayPort 1.4 RX Subsystem (DisplayPort example), DP RX IP stops after 4~5 hours.

Jump to solution

Dear Xilinx experts.

Thank you very much for your support and kind answers.


I implemented a design using DisplayPort 1.4 RX Subsystem (DisplayPort example).

My Vivado and SDK version is 2020.2. The device is xcku115-flvf1924-e-i.

My PC has GeForce GTX 1050 Ti graphic card with Windows 10 OS.


The DP Rx IP works well at start up, however DP RX stops after a 4~5 hours.

The DP_RX IP address is 0x44AC0000.

I checked the IP register map.

The difference between stopped condition and normal operation is as follows. All the other registers have same value in stopped condition and normal operation.

44AC000C: Enables the display timing generator in the user interface(value 1). 00000000(stop) 00000001(normal operation).

44AC02F0: [31:16] - Adaptive Sync Vertical Front Porch (VFP) derived based on Adaptive-Sync SDP reception. Assertion of Bit-31 of 0x070 has to read this register. 03A40000(stop) 02400000(normal operation).

44AC0114: Provides a mechanism for the host processor to monitor the state of the video datapath. This bit is set when vsync is asserted.
[3] - State of the vertical sync pulse for Stream 4.
[2] - State of the vertical sync pulse for Stream 3.
[1] - State of the vertical sync pulse for Stream 2.
[0] - State of the vertical sync pulse for Stream 1.
00000001(stop) 00000000(normal operation).


I don't know how to solve this problem.

I will really appreciate if I can be given solution or advice.

Thank you very much

 

Ick-Sung Choi.

Hi @chldlrtjd 

 

Which license are you using for DP ? Evaluation license or purchased license ?

 

I guess you're using an evaluation license.

If so, this behavior is limitation of evaluation license.

 

If you'd like to resolve it, you have to purchase a valid license for DP.

 

Hope this helps.

 

Best regards,
