DTB viewer

DTB viewer is a dedicated online tool that accepts Device Tree Blob (DTB) files and presents their hierarchical hardware description in a readable, navigable form.
It is intended for kernel developers, embedded engineers, and hardware bring-up teams who receive DTB binaries from boards or builders and need a quick, containerized way to verify structure without installing specialized toolchains.

Conceptually, the tool performs a binary parse of the DTB: it validates the header, reads the structure and strings blocks, reconstructs a tree of nodes and properties, and exposes this model for inspection, filtering, and export. It does not modify the original data, and it operates entirely in memory during analysis to avoid altering the source binary.

Value arises from accurate extraction of node names and properties, diffing against a reference DTB, and exporting the results to pipelines or reports. Typical use cases include verifying vendor-provided DTBs against a gold reference, auditing changes between kernel versions, and extracting properties such as compatible, reg, and interrupts for further validation.

Core features include file upload, automatic parse, hierarchical navigation, property listing, and data export in JSON or text formats. The tool supports filtering and searching by property names, and offers a lightweight diff view to highlight changes. Designed for scalable online use, it handles DTBs commonly found in development boards and simulation targets.
