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

[marioruiz]

Hi @Kamal,

I suggest you read the DMA tutorial to understand how to configure the PS and how to connect the DMA in your design. This part is missing, your DMA has no path for data transfers to the PS.

Tutorial: PYNQ DMA (Part 1: Hardware design)

PYNQ DMA tutorial (Part 1: Hardware design) This tutorial will show you how to use the Xilinx AXI DMA with PYNQ. It will cover adding the AXI DMA to a new Vivado hardware design and show how the DMA can be controlled from PYNQ. This tutorial is based on the v2.6 PYNQ image and will use Vivado 2020.1. If you are using a different PYNQ version you should be able to follow the same steps in this tutorial, but you should make sure you are using the supported version of Vivado for that PYNQ release. …

The sobel filter has two outputs, you should connect and consume from them. Otherwise, the IP will not work. You cannot leave one of the manager interfaces unconnected.
