Devicetree

General

A devicetree is a data structure used to describe hardware. The GAP SDK use devicetree to:

• Define unique hardware peripherals instances;

• Setup devices configuration structure;

• Configure chip’s pads;

• Create default references to a type of devices (ram, flash, …).

The pages below provide guides about how the devicetree is implemented in GAP SDK.

• Introduction to devicetree
• Devicetree source files
• Interaction with Kconfig
• Device tree parsing process
• Devicetree output

The pages below offer a step-to-step tutorial about how to use devicetree within GAP SDK.
