Hello
I am trying to load an overlay and configure FPGA from a bitfile generated using Vivado 2021.2.
I followed the video in the link below to design a simple adder IP overlay (Overlay Tutorial — Python productivity for Zynq (Pynq))
- YouTube
In jupyter when I run the first cell
from pynq import Overlay
overlay = Overlay('/home/xilinx/pynq/overlays/adder/adder.bit')
I get this error
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call last)

607 return parser
RuntimeError: Unable to find metadata for bitstream

Can anyone help me resolve this error
Thanks in advance
