I have built custom HLS video processing cores for the Z1 and was successful in building a custom overlay that worked as expected with the hdmi in and out tie. I took this same core and changed it from 24 bit to 48 bit to target the ZCU104 (changing the referenced board part accordingly). I also placed the core in-between the color_convert and pixel_pack cores as I did in the Z1. After rebuilding the bitstream I then added the 3 custom system files to my PYNQ SD card (custom.bit, custom.hwh, custom.tcl). Using the Overlay class my script successfully loads the new overlay but when I run the following code to configure the hdmi I got an errror:
Is there something obvious that I’m missing?
