Trying to recreate Digilent Zybo HDMI Z-20 design

[Cherif]

Hello,

 

I am trying to re-create the design located at Digilent HDMI Demo Design and I am having issues re-creating it. Is there somewhere where I can get a compiled version of it? I just want to run it to see how it works and my project involves something else.

Thanks,

Cherif

HI @Cherif,

Welcome to the Digilent forums!

Vivado projects are version specific. The Zybo-Z7-20-HDMI project is made for Vivado 2016.4.  I have generated a bitstream and imported the application/bsp into SDK in vivado 2016.4. Here is the completed project. I can be found in the proj folder. I have attached screen shots and a picture with the project working. 

best regards,

Jon

Hi Jon,

Thanks a lot for your help. I tried it and here is what I found. I am using Linux and 2016.4

Test 1:

1- I loaded the YourProject as you posted it

- Then when I go to SDK from Vivado.  SDK does not come up.

- Then I invoke SDK from the command line

 - Program the bit file into the FPGA

  2- Right click on HDMI-in  ->  run as   ->  launch on hardware (GDB)

I see the following message error:

Unexpected error while launching program: Error while running ps7_init method.

No Elf file associated with target.

 

Test 2:

- Load the project you made available

- Run Synthesize, Implement and generate bit stream

- Delete .SDK directory from your directory

- Export bitsteam

- Launch SDK from Vivado

in SDK create an empty application

- go to src directory right click ->  Import -> general -> File system -> and  /yourProject/sdk/hdmi/src

- select the files and import

Load   bit file into FPGA

- Right click on HDMI-in  ->  run as   ->  launch on hardware (GDB)

I see the following message error:

Unexpected error while launching program: Error while running ps7_init method.

No Elf file associated with target.

 

Am I doing something wrong here?

Thanks,

Cherif

PS: I tried to load screen shots but was not able. I do not see where it says load pictures.

Hi Jon,

 

I have tried reading this design using 2018.3 and everything works fine. I am not what the problem was.

Thanks for your help.

Hi @Cherif,

To clarify you were able to get the project running correctly in Vivado 2018.3?

best regards,

Hi Jon,

 

Sorry for the delay. I wanted to make sure what I have before I report.

Yes I can read your project with 2018.3. And if I synthesize, implement and generate bit stream without updating the IP it works. I can run the application with no problem.

However, when I report and update the IP and go through the whole process again of generating the bitstream, the application does not work.

I am not sure what is happening. Do the Diligent video library IP  have version also?

Thanks,

Cherif
