Hi I am trying to build Pynq for microzed board, and in my case it is absolutely not standard build. I started with GitHub - FredKellerman/Microzed-PYNQ, but there is no prebuilt image and it was so outdated that I tried to build my own. I am on Ubuntu 2022.4, looks like not supported, and using Vivado 2024.1 tools(not supported as well). I did struggled for couple of days and was able to get thru most of compilation, to the point, then rootfs is created with qemu.sh and stuck this time.
it cannot get clone PYNQ-Metadata from internet. I checked that I can access github and repo but pip is not happy.
I added ping github.com to qemu.sh script and see that it can get to github, output of the error on screen below.
I would welcome any help.

Ok I made progress by adding
git config --global http.sslVerify false
but still some security errors then it installs dependencies.
to qemu.sh

What really helped is to add --trusted-host to pip install
$ pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org pip

It looks like I am almost there, having issue on packaging wic image now.

Ok, it looks like an issue inside petalinux-package wic, for some reason they expect that temp wic partitions/images are named starting with “rootfs-” prefix, but it is not the case now, they start with “image-”. after that fix I was able to boot my image on mz7020, hope overlay loading will work!

@alexian79 - I’m curious how you root caused this bug … I’m looking at 2024.1 PYNQ right now and seeing the same issue… and what exactly did you fix to get wic to complete?

Hi, a bit hard to remember exactly. It was crashing on file rename, image generation is actually finished and rename operation is failed. You can do it manually.
you can see on screenshot commented couple lines for debugger breakpoint. you can insert that and see what file it was looking for, I remember that prefix for the file have changed. I dont remember if this local on screenshot is fixed or not :(. Please try this and let me know. If you will stuck let me know and I will spend more time on remembering.

Brilliant! Thank you for that pointer … I do see the file and bug in PLNX_20241_INSTALL/scripts/libs/package_wic.py …
PYNQ Makefile will handle this correctly in future release by simply grabbing the image file directly
