[Ruban1]

Blank screen on connecting to LVDS to imx8mm for Android 10 OS .Throught the recommended chip suggest by the NXP . SN65DSI83TPAPRQ1 . Only the touch is working and back light is working .But the screen is blank. Should i enable any config . Or do you have any  steps followed for Android 10 OS to support mipi to LVDS.

Hi Ruban

unfortunately SN65DSI83 is not supported in NXP BSPs, one can look at example on below

link and port it to Android

Hi Igor,

         From the Link which you have sent .In the topic 

"Definition of the SN65DSI83"

the entire function from i2c3

Where should i place that function. Because his not mentioned anything about that. Should i place in Kernel dts or U boot dts or in any patch. Because i gone through their dts file both kernel and uboot. It was not added. I am not able to find out which path they have added.

Kindly Support

Thanks and regards

for configuring according to link you have provided. Should i edit or should i add the snippet code.

And in which file should i add or edit in imx8mm-evk.dts file or imx8mm-evk.dtsi file . And for all the config should i do with standard or with the LVDS distibuter according to the display

The link you have suggest is only for yocto and debian.

In the link if you scroll down to last . you will find Categories which it will support

It doesn't support to Android OS

Android is based on linux, so that link is relevant to your case.
