Use the SDI and HDMI/DisplayPort ports

Question

Hello. I'm new with Ultrazed -EV. Im trying to modify the VCU Example Design (2018.3) as starting point. My main idea is to inyect a signal in the HDMI/Display port and send it directly to SDI output. Someone have experience using both ports ? Do you have some example to start with this ?

So the main idea:
Input : HDMI or DisplayPort ( My real input is a DVI)
Output: SDI (3G HD-SDI)

Best.

HI there,

While I can't support you very much as this is not released, I would suggest you take a look at the VCU design that we already ported for 2020.2 tools:

https://github.com/Avnet/petalinux/blob/2020.2/scripts/make_uz7ev_evcc_hdmi_v.sh

Pull our repositories down and checkout the 2020.2 branches, then run that script. That will get you a design. I am not complete with the documentation on this, but after booting, if you press SW1 the HDMI output should turn BLUE @ 4KUHD output. From there, you can run the various scripts that are included in the root home and test this out.

That's probably the fastest way to get you to the point of messing around.

Hi there, You can take that clock and pipe it back out with appropriate divisors. Although, personally, if the GTH is running (use something like IBERT), then it is connected. --Dan
