Hdmi port is not enabled

sandeepa — Wed, 20 Dec 2017 21:55:27 GMT

I built yocto project from qt website everything is working good but when I connect IMX6q sabrelite board to monitor through hdmi it is showing no video sources.Here I am attaching putty log.Qt is up in our build.Please find my u boot configuration

bootargs 'console=ttymxc1,115200 root=/dev/mmcblkp2 rootfstype=ext4 enable_wait_mode=off video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=28M mxc_hdmi.only_cea=1 rootwait fixrtc rw'

bootcmd=mmc dev 1;ext4load mmc 1:2 10800000 /boot/zImage:ext4load mmc 1:2 0x12000000 mmc 1:2 0x12000000 /boot/imx6q-sabrelite.dtb;bootz 0x10800000 - 0x12000000'

From putty I can say that it could not able to detect hdmi port.Please can help me to fix this issuse.

Thanks

could you use demo image from official website to test first? can you output to hdmi using demo image? I tested on my imx6q SabreSD board, it's ok
