Device Tree Validator & Generator
Validate device tree syntax and AOSP compatibility, or generate device tree templates based on your device specifications. Ensure your device trees follow best practices and are compatible with the latest AOSP versions.
What is the Device Tree Validator & Generator?
The Device Tree Validator & Generator is a comprehensive tool for creating, validating, and optimizing device tree configurations for AOSP devices. It ensures your device tree source (DTS) files are syntactically correct, AOSP-compliant, and follow hardware description best practices for optimal system performance and compatibility.
Supported Device Tree Components:
- •Device Tree Source (.dts) - Main device configuration and hardware description
- •Device Tree Include (.dtsi) - Shared configuration templates and common definitions
- •Overlay Files (.dtbo) - Dynamic device tree overlays for modular configurations
- •Binding Documentation - Hardware binding validation and documentation generation
Validation Accuracy
Detects syntax and compatibility issues with high precision
Template Generation
Time to generate complete device tree template

💡 Best Practices for Device Trees
• Use descriptive node names that clearly identify hardware components
• Follow naming conventions established by the Linux kernel and AOSP
• Include proper documentation for custom properties and bindings
• Validate against schemas to ensure compatibility and correctness
• Use overlays for variants to maintain modular device configurations
• Test thoroughly on target hardware before production deployment
