ZCU106 VCU TRD 2019.1 SDI Tx example not working


I am using ZCU106 VCU TRD 2019.1 examples as it is, i.e. without any compilation or building.
I am able to sucessfully run HDMI Tx example and it can read a TS file from SD Card or USB, decoding it and displaying over monitor (as shown in the image).
However when I run SDI Tx example using same TS file, it gives me error "ERROR: vgst_config_options() failed, error code "VLIB DRM Plane Not Found".
I tried to run the SDI Tx through stream input as well, but it failed too, giving following error "ERROR: vgst_start_pipeline() failed error code "state change failed". 

I was thinking if it had been an input file encoding issue, why did it run in case of HDMI.
I am just passing my own TS file name,  input resolution, and UDP IP information in .cfg files provided in the original TRD, but nothing works.

However I am able to see output monitor tuned up when I run the following command.
$ xmodetest -M xlnx -s 36:1920x1080-60@XV20  -w 36:sdi_mode:2 -w 36:sdi_data_stream:2 -w 36:is_frac:0 &

I am using an SDI to HDMI convertor to get SDI output from ZCU106.

Any guidance and suggestions are highly appreciated as I am a beginner working with VCU TRD.

Thanks in advance.

Hi @bilal5330 


Could you share log file or zoom-up two kind of console's picture ?

It is hard to make sure console messages for me.


Best regards

Re: ZCU106 VCU TRD 2019.1 SDI Tx example not working

Thanks watari,

I have attached the full log in attachment.

Here is the last excerpt from that log in the bottom.

Note: I am using "inpsdc.cfg" which is a copy of .cfg file provided in TRD for SDI-Tx example. (I have attached it as well).
I am only replacing my TS file name, FPS and resolution information in it. 

Thank you so much again,

Re: ZCU106 VCU TRD 2019.1 SDI Tx example not working

Hi @bilal5330 


I guess it seems clock source issue from boot log file.

But I don't have any idea to resolve this issue now.


Would you make sure clock source and AXI4Streaming clock on SDI Tx ?
