Question

Map analyzer (STM32Cube Build Analyzer alternative)

I'd like to share an open-source alternative to STM32Cube Build Analyzer, which may be useful for developers who don't use STM32CubeIDE (Eclipse or Visual Studio Code edition), or who build their projects using other tools such as Visual Studio or CMake directly.

GCCMapAnalyzer | Source.
(HTML file, hosted on GitHub Pages; click on GCCMapAnalyzer to run it in the browser.)

Functionalities

  • Tree view: Visualizes memory usage by memory region, section, and object file.
  • Memory Map: Displays symbols and sections in an address-space line diagram.
  • Section configuration: Allows customization of how sections are counted and grouped.

 


Note

I hope this post does not violate Community Guideline #5. I originally developed this tool to visualize an STM32H7 .map file before I knew about STM32Cube Build Analyzer, and I thought it might be useful for other community members as well.
