This is a customised Ardupilot firmware builder which allows to integrate custom patches, recall old builds etc. This is hosted on a private server but publicly accessible and the source code can be downloaded by anyone. Detailed instruction on how to build your custom firmware patcher based with this code are in the readme below. A live version of this app can be accessed here: https://ardupilot.equalmass.com

ArduPilot Custom Firmware Builder (EqualMass Edition)

🛠EqualMass Customization Layer (Added Feb 2026)

This repository has been customized to support a persistent, automated Patch Management System. These modifications allow for custom source code injection and regional data integration while maintaining a production-grade infrastructure on Debian 13.

📁 Modified & New Files

  • docker-compose.yml: Updated to include the overlay-manager sidecar service and shared volumes for persistent code injection.
  • builder/builder.py: Modified to detect custom source files in the /srv directory. The engine now automatically merges these overlays into the ArduPilot source tree before the Waf compiler begins the build.
  • web/templates/index.html: The main dashboard now features a stylized "Patch Manager" bridge button in the navigation bar to allow seamless switching between the builder and the sidecar.
  • overlay_manager/ (New Service):
    • main.py: A FastAPI-based engine designed to manage (Upload/Edit/Delete) custom source files within the Docker environment.
    • templates/index.html: A custom UI for managing patches, matching the ArduPilot ecosystem aesthetic.
    • static/logo.png: Localized branding assets for the sidecar interface.

🌐 Network & Routing Architecture

The system is unified behind an Nginx Reverse Proxy to provide a professional, single-domain experience:

  • Main Builder UI: https://ardupilot.equalmass.com/ (Proxied to port 11080).
  • Patch Manager: https://ardupilot.equalmass.com/patch-manager/ (Proxied to port 11081).
  • SSL Termination: Managed via Nginx for the equalmass.com domain.
