Ghidra SVD

Build

Import CMSIS SVD information onto your Ghidra memory map. This is usefull when reversing firmware from devices that publish SVD files. This is a re-write of another Ghidra SVD Loader plugin.

This is the preferred way to generate memory maps, but if no SVD files are available for your device you may want to try the Ghidra DeviceTreeBlob plugin.

Installing

Go to the releases page and download the latest version for your Ghidra distribution.

In Ghidra main window go to File > Install extensions.... In the new window press the + icon to import the downloaded zip.

Usage

In a CodeBrowser window press File > Import SVD....

A file dialog will allow you to select your SVD file and import it. Memory map will automatically be updated.

You may find SVD file sources in the following table:
