PYNQ-ZU - Could not find IP or hierarchy xfft in overlay

Hi @LightwishWONG,

Welcome to our community.
The ip_dict only shows memory-mapped IP, with an AXI4-Lite interface. The xfft you have in your design is not memory mapped, and the streaming interface is connected to a DMA

You can learn how to move data to this IP by following Cathal’s tutorial.

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. …
