the auboard_hdmi_pass_thru example design missing directions?

I have an aub15p board. I am trying to build the auboard_hdmi_pass_thru example design, but there are no instructions on how to do this. The three pages of documentation don't mention any changes to update the project from the 2023 software to the 2025 software. Is there a document I am missing?

This design reference design has not been re-targeted to different tools. It is an HDMI reference design from the tools version used and modified to make it function with the AUBoard. There is not additional documentation outside of what you have seen. Do you have specific questions that I could look into?

Hello could you simply explain how you get this ref design work ,because all my attempts to make it work fail,the board do not detect the hdmi_tx,no clock lock

all my devices work properly,I mean monitor and cable are ok, the design is absolutly identical from the 2023.1 design

I am running the project on Vivado 2025.1

I have to say again that when I am using the elf file and the hardware f file from 2023.1 project it's work,but when I buid the project i have the issue describe above

regards

The key is SW modifications to make sure the reference clock circuit is properly accounted for. This is the usage of the 8T49N241 clock chip (if I got the part number correct) versus the reference design SI Labs part..

The clock generator is controlled by the reference design and changes frequency depending on the frame rate / resolution used.
