Adding custom 4.3inch display in Marshmallo for iMX6SL

[jansirani]

Hai,

we have a custom board similar to iMX6SLEVK.

In that Kitkat4.4.2 ( kernel 3.0.35),we successfully integrated our custom 4.3inch display(480x272 with RGB888).

Now we want to integrate our custom display(480x272 with RGB888) to  Marshmallo6.0(kernel version : 4.1.15)

what we want to know is inorder to integrate our custom display(480x272 with RGB888) to Marshmallo in which kernel is using dts concept where we have to do changes in the kernel.

Thanks & Regards,

D.Jansirani

Hi Jansi

in kernels using dts concept timings are adjusted in imx6sl-evk.dts, display-timings {

linux-2.6-imx.git - Freescale i.MX Linux Tree

Hai  igorpadykov ,

Thanks for the reply.

But i don't have imx6sl-evk.dts file in  /myandroid/kernel_imx/arch/arm/boot/dts/ folder.

i am having only "imx6sl.dtsi" file in the same path for sololite.

i added the display timings in the "imx6sl.dtsi" file stiil my display resolutions / parameters not changed.

please tell me how to add my custom display parameters to Android OS-kernel.

Just to update , we want to integrate our custom dispaly(RGB888) to  Android Marshmallo Operating System.

Thanks & Regards,

D.Jansirani
