We are using imx6Q custom platform for our development which is based on sabresd platform.
We are using Linux 3.14.28_1.0.0-GA BSP for our development.
Our primary display is connected with LVDS0. The pixel format is RGB24 and bpp is 24. With this display, we are not able get the Yocto GUI.
In addition, we have tested with another display (RGB666 & 16 bpp). Here we are able to get the Yocto GUI.
Please let us know, why the YoctoGUI is not able to get in 24bpp display?
Have you tried the uboot parameter pass to the kernel.
you need to tell kernel the "if" is RGB24.
For the timing for the LVDS panel, please check the devices tree bindiing guide.
And make changes according to the datasheet of the lvds panel.
Actually, the uboot "if" also can use the fsl,data-width in device tree to define.
