I created a DFX project with one reconfigure partition, which include only one IP using axi interface. I successfully generate the bistream and I put it on my KV260 board along with the partial bitstream and hwh file. But after I download the partial bitstream, I cannot use the IP even though I can see different IP names. The error says:

PermissionError: [Errno 1] Operation not permitted
Here is the block design of my project:
And how I download the bitstream (sorry I cannot provide another screenshot because I’m a new user):
import numpy as np
import time
from pynq import PL, allocate, Overlay
PL.reset()
ol = Overlay("test.xsa")
# download partial for hierarchy rp_0
ol.rp_0.download('add.bit')
# after both download, if I check rp_0 I see different IP blocks in it
ol.rp_0.download('sub.bit')
# but when I try to use the ip inside of rp_0 I got the error above
ip = ol.rp_0.sub_0
I didn’t find any similar problem over the Internet. Besides, since pynq is installed for root user, there shouldn’t be any permission issue, right? I tried use sudo to execute python script but I got the same error.
I’m using PYNQ-3.0.1 on Ubuntu 22.04. Any help is appreciated!
