Hi, I’m trying to create PYNQ bsp for Minized. I have created system with fpga manager, jupyter notebook, pynq packages. But if I’m trying to import PYNQ Im getting this message: /usr/lib/python3.5/site-packages/pynq/lib/video/ **init**.py in 38 from . import clocks 39 —\> 40 if pynq.ps.CPU\_ARCH == pynq.ps.ZYNQ\_ARCH: 41 from . import dvi 42 elif pynq.ps.CPU\_ARCH == pynq.ps.ZU\_ARCH: AttributeError: module ‘pynq’ has no attribute ‘ps’ Is this error connected with Minized not containing any video output? How can I fix those errors? I’m missing some library? Thanks for help ---

So I’ve just removed this line and dvi library. Now PYNQ throws “ConnectionError: Could not connect to PL server” Isn’t fpga manager PL-server for PYNQ? ---

The PL server is a separate process which would normally be started by init. Given the errors you are seeing it’s likely that the server failed to start. You can run `start_pl_server.py &` on the console to start it manually. I’m a bit worried by the error messages you are seeing - that shouldn’t be happening and indicates some form of circular inclusion on our part. I don’t know why this would be an issue for the minized. If you get a finish your BSP would you be willing to share it so I can try and get to the root of the issue? Peter ---

Hi, I have tried using start\_pl\_server.py, here is output: start\_pl\_server.py start\_pl\_server.py sr/lib/python3.5/site-packages/pkg\_resources/ **init**.py", line 479, in load\_entry\_point return get\_distribution(dist).load\_entry\_point(group, name) File “/usr/lib/python3.5/site-packages/pkg\_resources/ **init**.py”, line 2703, in load\_entry\_point return ep.load() File “/usr/lib/python3.5/site-packages/pkg\_resources/ **init**.py”, line 2321, in load return self.resolve() File “/usr/lib/python3.5/site-packages/pkg\_resources/ **init**.py”, line 2327, in resolve module = **import** (self.module\_name, fromlist=[‘ **name** ’], level=0) File “/usr/lib/python3.5/site-packages/pynq/ **init**.py”, line 47, in from . import lib File “/usr/lib/python3.5/site-packages/pynq/lib/ **init**.py”, line 74, in from . import video File “/usr/lib/python3.5/site-packages/pynq/lib/video/ **init**.py”, line 41, in from . import dvi File “/usr/lib/python3.5/site-packages/pynq/lib/video/dvi.py”, line 41, in import pynq.lib.\_video ImportError: No module named ‘pynq.lib.\_video’ [MinizedBSP.bsp](https://discuss.pynq.io/uploads/short-url/avvHaeaBvWyoMQk6Da8jr71RzRT.bsp) (2.5 MB) This is output from fresh install. Now I’m trying to get latest pynq and pandas from pypi, because petalinux 2019.2 have 2.4 pynq version included in meta-pynq which is outdated. I will try to one more time after update finishes. ---

So I have reinstalled pynq package to version 2.5.4 via pypi and now it behaves differently. First start\_pl\_server.py ![1freeze](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/1/167a072697b6fa1c836c9827f32b352c169e924a.png) Just a freeze and no reaction from ZYNQ.

The `start_pl_server.py` script is designed to run forever - hence why we aim to start it at boot. If you run it in the background with ``` start_pl_server.py & ``` Does that make the core PYNQ library function correctly? ---

Okay, its seems to work after updating to version 2.5.4. ![Screenshot from 2020-07-27 12-54-10](https://us1.discourse-cdn.com/flex019/uploads/pynq1/original/2X/2/297e24712b58e62dcd49e36643963e8b8b76cf6f.png) I can’t test it properly for now because while creating new overlay my wifi and mmc driver freak out so I’m losing wifi connection. I will make some tests after I get over this issue. PS1. Is there any petalinux recipe for 2.5.4 version? Installing new pynq version via pip3 in minized is pain. PS2. How can I create HWH file? Right now Im using TCL and Bitstream? ---

Petalinux 2020.1 has 2.5.1 in it which (for Z|YNQ) should be functionally identical to 2.5.4. The updated recipes are [here](https://github.com/Xilinx/meta-xilinx/tree/master/meta-xilinx-pynq/recipes-devtool/python) and should be portable to 2019.2 if it’s important for you to stick with the old version.

I have created pynq based on Xilinx PYNQ from github, not via raw petalinux. Now it is working.
