Description
This is a continuation of QTBUG-76857.
I have the same crash, but was able to reproduce a stack trace.
My application that is little more than a WebEngineView wrapped in a Window is started on the target as follows:
export="QT_QPA_FB_TSLIB=1" export="QT_QPA_EGLFS_PHYSICAL_WIDTH=304" export="QT_QPA_EGLFS_PHYSICAL_HEIGHT=228" export="QT_QPA_EGLFS_NO_LIBINPUT=1" export="QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event0" export="QT_QPA_EGLFS_TSLIB=1" export="FB_MULTI_BUFFER=2" ./utsbrowser -platform eglfs
It crashes during startup with:
Unhandled prefetch abort: breakpoint debug exception (0x002) at 0x7235c544
Trace/breakpoint trap
backtrace:

Note: I build also a BSP with Qt 15.0 but that didn't make a difference, application still crashes with Unhandled prefetch abort.
