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
