Hello,
I think I have a similar problem.
I'm trying generate an image using Yocto 1.8 - Fido , MACHINE =colibri-imx6,
core-image-minimal
DISTRO_FEATURES_remove = "x11 wayland nfc 3g bluetooth irda"
IMAGE_INSTALL_append = "\
dbus \
kernel-modules \
packagegroup-qt5-qtcreator-debug \
qtserialport \
qtbase-plugins \
cinematicexperience \
qt5nmapcarousedemo \
qtsmarthome \
quitbattery \
tslib-conf \
freetype \
fontconfig \
evtest \
"
After try run the Cinematic Experience I get this error message
Could not open egl display
Aborted
export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1
./Qt5_CinematicExperience -platform eglfs
Could not open egl display
Aborted
I will try to compile the fsl-image-multimedia-full, with X11 to test if works.
