qt.qpa.xcb: could not connect to display ?

[_APM_]

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimal, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

@_APM_ This was asked many times here. You should use the search function.
To debug such plug-in issues set QT_DEBUG_PLUGINS before running your application and check the output. See https://doc.qt.io/qt-6/debug.html

You did not say anything about your platform: do you have X11 running?

@_APM_ it is simple run it directly from the target board and it will work
