DMA Tutorial Bitstream Overlay Problem

Support
1

Using RFSoC 4x2, PYNQ 3.0.1

I tried to implement the DMA tutorial from this link using the .bit and .hwh files given on corresponding github page.

I put the files in a folder I created (trials/DMA/), but when I try to run the following

from pynq import Overlay

ol = Overlay("./dma_tutorial.bit")

it does not work, and instead it gives the error given in the attached screenshot.

What can be the problem? Is there a forward solution to it?

Respectful regards

Hi @ljbedir,

The files provided in that repository a for the PYNQ-Z2.
You will have to rebuild the overlay for the RFSoC 4x2.
