Hi moowon,

Please try X-11 image on i.MX 6Quad SABRE-SD

$ MACHINE=imx6qsabresd source fsl-setup-release.sh -b build-x11 -e x11

$ bitbake fsl-image-gui

To run test applications, you have to first load the GPU driver.

To load the GPU driver, use the following command:

"insmod /fgalcore.ko"

to un-install GPU driver, run the following command:

"rmmod /galcore.ko"

Note: The path of galcore.ko can be found by the following command:

"cd / && find . -name "galcore.ko" "

The script is located at Yocto rootfs /unit_tests/. There are three ways to run it.

Normal run to get all gpu related processes information:

>/unit_tests/gpuinfo.sh

Hope this helps
