Is there any link so I can find am335x-olimex-lcd_* device tree sources

JohnS

Supposed to be in such as am335x-olimex-som.dtb -- are they not there?

John

hamdi

I cannot find them any where

bruceuk

Could it be these?

$ more ./olimex-github/linux-3.12.10-ti2013.12.01-am3352_som/arch/arm/boot/dts/am335x-olimex-som.dts

hamdi

that is default device tree which load vga "cape" , I think      native-mode = <&vga1024x768>;
is the line which I should change to have my 4.3" lcd working .
