Eclipse Embedded CDT

A family of Eclipse CDT extensions and tools for GNU Arm & RISC-V development

GNU MCU → Eclipse Embedded CDT!

In 2020, the GNU MCU/ARM Eclipse project was migrated to the Eclipse Foundation as Eclipse Embedded CDT (C/C++ Development Tools); starting with v5.1.1, all future releases will be available from the Eclipse Foundation.

Eclipse Embedded CDT is an open source project that includes a family of Eclipse plug-ins and tools for multi-platform embedded ARM and RISC-V development, based on GNU toolchains. This project is hosted on GitHub. The former project was hosted on GitHub and SourceForge.


RISC-V logo Starting with Eclipse plug-ins v4.x, the project was enhanced with support for RISC-V devices, thus the new MCU name, more appropriate for a multi-platform project. For more details, see the RISC-V Corner and xPack GNU RISC-V Embedded GCC page.

The Eclipse Embedded CDT plug-ins

GME logoThese plug-ins provide Eclipse CDT (C/C++ Development Tooling) extensions for GNU embedded toolchains like GNU Tools for ARM Embedded Processors, Linaro, xPack GNU RISC-V Embedded GCC, etc.

In short, the Eclipse Embedded CDT plug-ins allow to create, build, debug and in general to manage ARM & RISC-V projects (executables and static/shared libraries, in both 32 and 64-bit versions) with the Eclipse framework (currently tested up to Eclipse 4.10 2018-12). The plug-ins run on Windows, macOS and GNU/Linux. For more details please visit the Features page.

Additional tools

Apart from the main Eclipse plug-ins, this project is accompanied by several other tools, distributed as separate packages.

  • xPack Windows Build Tools

    The xPack Windows Build Tools project includes the additional tools required to perform builds on Windows (make & rm).

  • xPack GNU Arm Embedded GCC

    The xPack GNU Arm Embedded GCC project is an alternate binary distribution that complements the official GNU Arm Embedded Toolchain maintained by Arm. Binaries for Windows, macOS and GNU/Linux are available.

  • xPack GNU RISC-V Embedded GCC

    The xPack GNU RISC-V Embedded GCC project is a new distribution of the bare metal version of RISC-V GCC, maintained by SiFive. Binaries for Windows, macOS and GNU/Linux are available.

  • xPack OpenOCD

    The xPack OpenOCD project is a new distribution of OpenOCD, customised for a better/more convenient integration with the OpenOCD Debugging plug-in. Binaries for Windows, macOS and GNU/Linux are available.

  • xPack QEMU Arm

    The xPack QEMU Arm project is a fork of QEMU (an open source machine emulator), intended to provide support for Cortex-M emulation in GNU MCU Eclipse. Binaries for Windows, macOS and GNU/Linux are available.
