Hello, I use i.MX6qsabresd platform and fsl-yocto-3.14.28 BSP

I use a lvds screen on the imx6qsabresd borad.

I input the following command

(1)MACHINE=imx6qsabresd source fsl-setup-release.sh –b build-fb –e fb

(2)Edit yocto/build/conf/bblayers.conf to add the meta-qt5 layer at the end:

${BSPDIR}/sources/meta-qt5 \

${BSPDIR}/sources/meta-openembedded/meta-ruby \

${BSPDIR}/sources/meta-openembedded/meta-multimedia \

(3)Edit yocto/build/conf/local.conf

Hello yiyi521,

I’m sorry to hear you’re having troubles with the QT5 image. Have you tried using X11 as backend? QT5 requires this backend in order to work properly. That is very likely at least part of the problem.

Let us know of your findings!
