I was looking into the UltraZed-EV TRD designs and have a few questions:
1.) What is the difference between the hdmi and hdmi_v designs?
2.) I can't seem to get the HDMI Rx to work. I see that there are some scripts in the home directory, but I can't seem to get any of the hdmi scripts to work. (hdmi_passthru.sh, hdmi_to_vcu_to_hdmi.sh, etc).
This is the output I get when running the hdmi_passthru script:

I'm assuming these scripts should be working for each release. Any ideas what I'm doing wrong? Please let me know.
