Version 7.3.1-1.1 is a new release of GNU MCU Eclipse ARM Embedded GCC.

Download​

The binary files are available from GitHub Releases.

Compliance​

This release follows the official GNU Arm Embedded Toolchain 7-2018-q2-update release from June 27, 2018 and it is based on the gcc-arm-none-eabi-7-2018-q2-update-src.tar.bz2 source invariant.

Binaries​

Binaries for Windows, macOS and GNU/Linux are provided.

The GNU/Linux binaries were built on two CentOS 6 Docker images (32/64-bit), and run on any distribution based on CentOS 6 or later.

The macOS binary was built on a macOS 10.10.5 and must run on any newer macOS system.

The Windows binaries were built with mingw-w64, and run on any reasonably recent i686 and x86_64 Windows machines.

Instructions on how to install the binaries are available in the Install Guide.

The toolchain is also available as an xPack and can be conveniently installed with xpm:

xpm install --global @gnu-mcu-eclipse/arm-none-eabi-gcc@latest

This installs the latest available version.

For better control and repeatability, the build scripts use Docker containers; all files required during builds are available as a separate gnu-mcu-eclipse/arm-none-eabi-gcc-build project.

Known problems​

  • due to some changes in newlib, the definition of the _EXFUN macro changed and the semihosting projects fail to build with a compile error in system/src/newlib/_syscalls.c. The problem is in the project template, and a fix will be available in the next release of GNU MCU Eclipse plug-ins #317.
