How Do I Setup HDMI with Arty Z7-20?

[woj]

Im using an ARTY z7-20 and vivado 2024.1

I'm trying to use the HDMI ports to input a live camera feed into the input and then transmit it through the output port to a monitor. I followed this video for the design and it seemed very simple.

https://www.youtube.com/watch

I've seen the demo that is associated with the HDMI arty z7 set up but couldn't get it working, its not exactly what i need and it was somewhat out dated so I had trouble following.

 

Anyways I'm having a lot of trouble getting this going and i feel like it should be pretty straight forward based of the video i watched so i wanted to see if anyone can help out/ get a second pair of eyes on the situation. Thanks in advance.

 

Errors I encountered:

one major problem i had was with the dvi2rgb IP block. When i first put it in the block design vivado said it was configured for the Arty z7 -10 but there was no way to change it and my project was set up for Arty Z7 -20 before i placed any IP blocks. Then, using the linter, i got the errors shown below. The ip wasnt able to read dgl_720p_cea.data so I copied it and put it in the exact folder that EEPROM_8b was so that EEPROM_8b could read it because that was the file that was referencing dgl_720p_cea.data. After doing that, the linter worked with no errors but if i touch the block design i made that contains the IP blocks it will delete the dgl_720_cea.data from the folder i copied it to and the linter will once again output the errors below.

Hi @woj,

I'm not sure what video you watched as there is no actual video associated with the link you provided, but I tested the HDMI input demo for the Arty Z7-20, https://digilent.com/reference/programmable-logic/arty-z7/demos/hdmi-input, on 2023.1 (the latest version that Digilent has available) with the direct Vitis import and the direct pass through (computer -> Arty Z7-20 -> monitor) worked without issue.

I also confirmed that generating the bitstream and using that hardware platform (.xsa) in the Vitis project also works as intended, so that should help you with a working block design that implements HDMI passthrough on the Arty Z7-20.

Let me know if you have any questions.

Thanks,
JColvin

Thanks for the response,
The website you mentioned has updated files. The first two digilent HDMI demos on google contain only the files from 2016 which is what i was working with orignally. 

I followed the demo you sent and ran in to trouble with importing the Vitis Archive File. I clicked File>import and selected the zip folder but it doesn't show any components for me to select. I was wondering if I need to have Vivado and Vitis 2022.1 for this demo to work properly because right now I have 2024.1
thanks, Matthew

Update: The components only showed up when I used the Vitis classic 2024.1 not Vitis 2024.1

Ah yes, I should have mentioned that our demos use Vitis Classic. We have plans to update our materials and demos to work with the new flow offered by the new (2023.3 and later) Vitis IDE, but this has not been completed as of yet.

Thanks,
JColvin
