Hi,

@shiqi17

When I use ‘‘overlay?’’ instruction ,I can’t find the LSTM_Top_0 IP.

I have answer this here:

Hi @shiqi17, Only memory mapped IP will appear in the ip_dict. Your IP is AXI4-Stream, so it will not be displayed in the ip_dict. Mario

I suggest you check out the DMA tutorials:

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. …
