Using KIT LCD15.6" Touch LCD with imx6 sabre infotainment platform

[taesungheo]

Hello all,

I am trying to connect KIT LCD 15.6" Touch LCD ( from UDOO ) with Imx6 Sabre Infotainment platform by NXP.Specifically, the board I am using from NXP is combination of MCIMX6xAICPU2 (with sabre quad cpu) and MCIMXABASEV1 (base board).

I uploaded Yocto OS to Imx6 Sabre Infotainment platform using SD card.
I managed to match the LVDS pin maps between UDOO LCD panel and Imx6 Infotainment board.
Also, I properly powered 12V to the UDOO LCD using EXT POWER provided by NXP's base board.
And I changed the U-boot environment settings to use my first monitor as LVDS with 1366x768 resolution as below.
>> setenv mmcargs "setenv bootargs console=${console},${baudrate} root=${mmcroot} rootwait rw video=mxcfb0:dev=ldb,1024x600M@60,if=RGB666"

But the UDOO LCD does not display anything, and seems like the backlight is not also getting powered.
If there is anyone who succeeded in connecting the UDOO's LCD to any imx6 processor board from NXP, I would greatly appreciate if you could provide some hints regarding this.

Thank you all.

Hi igor,

Where is the dts file?

Is the file located under Yocto building source folder at Ubuntu machine? 

Or is it located at SD card?
