Linux and Zephyr RTOS uses DTS to desrbibe hardware: cpu, memory, peripherals, soc, boards, etc. That would give some compatibility and easier portabity to existing hardware! :-) I did some definitions of custom boards and hardware already in Zephyr. It is not really well documented along west project structure seems still under development (i.e. using global zephyr repo vs using per project different version local zephyr repo is possible not for that long). There are many examples but different ones offers different approach and there is no clear standard with examples (i.e. standard should provide several full working examples not just code snippets). Clear but extensible project structure is also important (but I am not yet there in NuttX). Anyways DTS would make portabity much easier also re-using existing hardware definitions would make migration to NuttX more attractive :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
