At 9 o’clock this morning, when I tried to download and run the mnist project, I was able to download the bit file normally，but just now when I tried to re-run the mnist project, I got a bug that I couldn’t download the bit file。 QAQ

Here’s some of the code I reported the error!!! 0.o
from PIL import Image
import numpy as np
import matplotlib.pyplot as plt
from pynq import Xlnk, Overlay
resize_design = Overlay(“resizer.bit”)
Here’s what I got in the error！！！！ 0.o

It seems that there is a problem with the “overlay”, but I don’t know how to fix it 0_0

Hi @ymcuse,

Welcome to the PYNQ community.

Have you tried restarting the board?
Looks like you are using an old version of the PYNQ SD Card. I would suggest you get the latest one 3.0.1.

Thanks for your reply，When I was browsing the forums, I found the answer to my question under another help post, and the reason for this bug was that I had used a bit file of a different model of FPGA by mistake QAQ
Thank you
