Sobel filter (Vitis vision library) implementation on Pynq-Z board

Hi,

I think that you should first address the lack of a path between the DMA and PS (HP ports).
HP port(s) in the PS are not enabled. Without this connection your design would never work.

You are missing a key step from the tutorial Tutorial: PYNQ DMA (Part 1: Hardware design)

If you do not want to use the second interface in the sobel filter, you could assert tready with a constant.
