Dual display operation on a Freescale i.mx6 Linux device
Recently I evaluated Yocto for the Freescale i.mx6 processor. I received a tremendous amount of information from the Open Source community and I want to gracefully contribute back the condensed information to the community.
Prepare for dual display operation (1 HDMI, 1 LVDS) in U-Boot (interrupt the boot process by a keystroke):
Boot and login to the system and start for example the cinematicexperience demo on HDMI:
./Qt5_CinematicExperience -platform eglfs &
Then on LVDS:
echo 0 > /sys/class/graphics/fb2/blank
./Qt5_CinematicExperience -platform eglfs -plugin tslib
(Howto build a Yocto image with cinematicexperience can be seen in Embedded Linux on the Freescale i.mx6 Sabre SD (Yocto, QT 5.3)).
