Creating custom DTS

Question asked by Luke Malpass on Dec 1, 2015

I have a custom board using the iMX6Quad processor. I've created everything from scratch for the software bringup (SPL, uBoot, Kernel 4.3 mainstream, modules, headers & source) except for the DTS as I cannot find any documentation on creating them.

 

The board boots fine if I used existing demo or dev boards as I have used existing DTS files from the 4.3 upstream kernel that match the dev boards, however if I try them on my own custom board it does nothing after the "Starting kernel..." stage.

 

I'm guessing its something in the DTS not matching my custom board so want to create a custom one to match my own board with GPIOs for LEDs also. However, where do I start and are there any tools for creating/editing the DTS/DTSI files?
