Hello,
Since I wasn't able to find a driver that allowed the GenX320 camera to work with the PYNQ framework, I ported the existing drivers to Python for this purpose.
You can find the code
here. The available example is geared towards my current project, but the underlying driver should work for any PYNQ project (I only tested it on the Kria KV260 though).
I am putting it out there for anyone to use, because PYNQ makes it easier to prototype than the Vitis flow in my opinion.
