Hi Ajmalali,

after bitbaking fsl-image-gui or fsl-image qt5 the output must be set to LVDS by default. If you are not familiar with bitbaking Yocto images please take a look here:

Yocto Training - HOME 

The discussion below may be useful too.

No display on LVDS while running fsl-image-multimedia-full on iMX6qSabreSD

Hi Carlos,

Thanks for the reply.

I don't have underlying Linux kernel. I am trying to display the image by using only bare-metal code. What all things do i need to do that ? Please Help.

Even if there is one or the other bare metal implementation for i.MX6 flying around, NXP does not support that (anymore).

However, when we talk about bare metal we forget most of the time that there is u-boot. It is not Linux. Among other things it contains support for the LVDS display we are using in combination with our i.MX6Q SABRESD board. During startup it already shows some penguins and text. Look into this doc:
