Eclypse Z7: Could not find UIO device for interrupt pin

Support
1

Hello, I am using a Digilent Eclypse Z7 running PYNQ v2.6. I created the PYNQ image and device tree overlay using this tutorial: Eclypse-Z7 PYNQ porting guide - Hackster.io

I am trying to control my ADC and DAC Zmods via the axi dmas. Currently I have this code:

import pynq
from pynq import Overlay
import os

ol = Overlay("/home/xilinx/jupyter_notebooks/BE/design_1.bit")
ol.download(dtbo="/home/xilinx/jupyter_notebooks/BE/pl.dtbo")

ol.ip_dict.keys()

dict_keys(['ZmodADC_0/axi_dma_0', 'ZmodDAC_0/axi_dma_1', 'axi_intc_0', 'axi_intc_1', 'axi_intc_2', 'ZmodADC_0/AXI_ZmodADC1410_1', 'ZmodDAC_0/AXI_ZmodDAC1411_v1_0_0'])

When I attempt to call the axi_dma_1 (or axi_dma_0 in the case of the ZmodADC), I am getting the following error:

ol.ZmodDAC_0.axi_dma_1

ValueError: Could not find UIO device for interrupt pin for IRQ number 2

Previously, I had encountered ValueError: ‘’, which I solved using the solution from this post: How to access the DMA in the module - #2 by sazc

So far, I have attempted a few things that were suggested in other posts. This post (Uio device - #2 by PeterOgden) suggested a few reasons but my build has everything correct. I have also tried to recompile pl.dtbo with FPGA manager as the end of the Hackster.io guide suggested disabling runtime reconfiguration as a possible fix. Lastly, I have tried the fixes mentioned in this post: Build PYNQ OS for ZCU102 with Yocto - #21 by PeterOgden.

As a note, when I try and call ol.ZmodADC_0.axi_dma_0, I get the same error for interrupt pin for IRQ number 1.
