Is the Zephyr Device Tree Too Complicated?
summary
Zephyr’s device tree enables reuse across boards but often forces redundant fields (I2C unit address repeated), opaque YAML bindings, and hard-to-follow DTSI include chains that leave beginners lost. Recent fixes matter: zephyr.dts shows source locations in builds, Nordic’s language-server gives LSP navigation and autocomplete, a graphical viewer and DTSH shell ease inspection, and a huge formatting PR (~1,000+ files) signals momentum. The verdict is maybe — tooling reduces friction but better abstractions for common I2C/SPI setups and clearer binding-driven editors would cut confusion.
