HDMI Black out Issue on IMX6

Hi,

 

I'm facing HDMI blackout issue on IMX6. I'm using linux-3.10.108 kernel version. Back ported  IMX DRM patches from linux-4.10 kernel version.

 

I'm running following weston command

weston --tty=1 -B drm-backend.so -c weston.ini &

 

When I'm adding gbm-format=rgb565 in weston.ini file, HDMI blackout issue is not observed.

 

So, Is it always necessary to provide gbm-format=rgb565 in weston.ini file?  or this is just a workaround.

 

 

Regards,

Vishnu
