Hi again,

I have tested the QtWebEngine with a qt example and I got:

# ./minimal -platform eglfs
Illegal instruction

Any idea of what could be causing it?

Hard to say without further information..., did your compile
minimal yourself or did you enable 'BR2_PACKAGE_QT5BASE_EXAMPLES=y'
and used the one installed as

'/usr/lib/qt/examples/webenginewidgets/minimal/minimal'

on the target?

I had enabled 'BR2_PACKAGE_QT5BASE_EXAMPLES=y' and I have used the one in
'/usr/lib/qt/examples/webenginewidgets/minimal/minimal'

Result of 'file minimal':

minimal: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically
linked, interpreter /lib/ld-, for GNU/Linux 4.19.0, stripped

I have no problems running other samples like the qtvirtualkeyboard or touch
ones

Please provide a complete .config (or defconfig) file...

Here my defconfig:  cp4_defconfig.cp4_defconfig
<http://buildroot-busybox.2317881.n4.nabble.com/file/t2824/cp4_defconfig.cp4_defconfig>

quoted

Still using buildroot-2019.02.09?

Yes

I can confirm your crash/illegal instruction with the provided config
using minimal example on RPi0 (it crashes somewhere in the static
constructors)...

Regards,
Peter
