Devicetree

A devicetree is a hierarchical data structure primarily used to describe hardware. Zephyr uses devicetree in two main ways:

  • to describe hardware to the Device Driver Model

  • to provide that hardware’s initial configuration

This page links to a high level guide on devicetree as well as reference material.
