Hello @TDurham
Okay, you system is not latest release. Please use OOWOW to install latest release image, it should work.
Will that wipe out the stuff I have installed?
ROS2
OpenCV
Yes.
The image you used is an early test image not release image.
Well that sucked. But it worked!
After installing the latest Ubuntu through OOWOW I now have serial port access but get the following error when running various applications
$ python3 depthai_demo.py

qt.qpa.plugin: Could not find the Qt platform plugin “wayland” in “/home/khadas/.local/lib/python3.10/site-packages/cv2/qt/plugins”
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: xcb.

These applications ran fine on the previous Ubuntu installation.
Any thoughts?
