Select a node · Drag to pan · Pinch or scroll to zoom

Drop or import a .dtb or self-contained .dts or paste one into the source editor. All parsing happens in your browser.

Navigate the map

Browse tree shows one bus and up to eight direct children at a time (four on phones). Use Explore children on a bus, Focus selected, Parent, Root and the page arrows to navigate. Search finds nodes across the document. Use Tree and Inspect to open or hide the side panels. On phones, panels slide over the map. Drag with one finger to pan and pinch with two fingers to zoom. The +, − and Fit controls remain available.

Source includes syntax highlighting. Changes apply only when you choose Visualize tree. Tab inserts indentation; Shift+Tab moves keyboard focus out of the editor.

Have a compiled DTB?

Import .dtb directly: decoding runs locally. The Source editor and export show reconstructed DTS with inferred value types. Original labels, includes and override history are not available. FDT version 17 compatible blobs are supported; standalone overlays are not applied.

Have a Linux DTS with includes or macros?

Compile it using your normal kernel or BSP build first, then import the resulting DTB directly. DTSee doesn’t run a C preprocessor or resolve files from your machine.

Hardware context and quick actions

The inspector decodes raw reg tuples from the immediate parent’s cell counts. Missing counts use specification defaults (2 address cells, 1 size cell), never ancestor values. Addresses remain bus-relative; CPU-address translation is not performed. I²C/SPI labels are parent-name hints. Declared status and effective structural availability are separate; neither predicts probe success.

Breadcrumbs and reference links reveal a node’s parent branch in Browse tree. Graph clicks preserve the current branch. Copy path/properties or export a Markdown node report from the inspector; if clipboard access is denied, copy from the fallback dialog.

What works in this prototype

Node hierarchy, properties, labels, symbolic references, in-file node overrides, native DTB import and common numeric phandle arrays files. Connections are inferred from references; they aren’t a complete wiring diagram.

Know the limits

No binding validation, address translation, macro expansion, external includes, plugin overlays, or deletion directives. Node status is the node’s own status, not a guarantee that Linux will probe it. Numeric references are decoded only for recognized property formats.

The included ARM example is illustrative and simplified, not a production board description. Imported trees are held in memory and disappear on refresh; export your edits to keep them.

Automatic clipboard access is unavailable. Copy the selected text below.

Your current tree, , will be removed from this workspace. Export any edits you want to keep first.

Your original file on disk will not be deleted.
