The GNU MCU Eclipse ARM Embedded GCC binaries

GNU MCU Eclipse ARM Embedded GCC

Rationale

GNU MCU Eclipse ARM Embedded GCC is a new GCC toolchain distribution for ARM devices, that complements the official GNU Arm Embedded Toolchain distribution, by ARM.

For main benefits for the users are:

• convenience: binaries for all major platforms are provided (Windows 64/32-bit, GNU/Linux 64/32-bit, macOS);
• uniform and portable install: the toolchain is also available as a binary xPack, and can be easily installed with xpm;
• improved support for Continuous Integration usage: as for any xPack, the toolchain can be easily used in test environments.

Changes

Compared to the original ARM release, there are no functional changes; the same architecture options are supported, and the same combinations of libraries (derived from newlib) are provided.

Releases

The GNU MCU Eclipse ARM Embedded GCC releases generally follow the official GNU Arm Embedded Toolchain releases, maintained by ARM.

8.2.1-1.7 (2019-05-24)

This release is functionally equivalent to 8-2018-q4-major from December 20, 2018, and is based on gcc-arm-none-eabi-8-2018-q4-major-src.tar.bz2 (download), but fixes the bugs present in the initial ARM release.

The intermediate releases 8.2.1-1.5 to 8.2.1-1.2 were deprecated.

8.2.1-1.1 (2019-01-02)

This release is functionally equivalent to 8-2018-q4-major from December 20, 2018, and is based on gcc-arm-none-eabi-8-2018-q4-major-src.tar.bz2 (download).

7.3.1-1.1 (2018-07-24)

This release is functionally equivalent to 7-2018-q2-update from June 27, 2018, and is based on gcc-arm-none-eabi-7-2018-q2-update-src.tar.bz2 (download).

There should be no changes compared to the ARM release.

7.2.1-1.1 (2018-04-01)

This release is functionally equivalent to 7-2017-q4-major from December 18, 2017, and is based on gcc-arm-none-eabi-7-2017-q4-major-src.tar.bz2 (download).

The only changes are small improvements to newlib, which was extended with --enable-newlib-io-c99-formats to enable C99 support in IO functions like printf/scanf. This option does not affect newlib-nano.

6.3.1-1.1 (2018-03-31)

This release is functionally equivalent to 6-2017-q2-update from June 28, 2017, and is based on gcc-arm-none-eabi-6-2017-q2-update-src.tar.bz2 (download).

The only changes are small improvements to newlib, which was extended with --enable-newlib-io-c99-formats to enable C99 support in IO functions like printf/scanf. This option does not affect newlib-nano.

Install

The procedure to install GNU MCU Eclipse ARM Embedded GCC is platform specific, but relatively straight forward (a .zip archive on Windows, a compressed tar archive on macOS and GNU/Linux).

A portable method is to use xpm:

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

More details are available on the How to install the ARM toolchain? page.

Build

The build scripts are part of the separate gnu-mcu-eclipse/arm-none-eabi-gcc-build project.

This project does not include any source files, the build scripts use the Source Invariant archives provided by ARM.

Publish

The procedure used to publish the binaries is documented in the separate PUBLISH page.

The metadata files used to publish the xPacks on the npmjs.com server are available from the gnu-mcu-eclipse/arm-none-eabi-gcc-xpack project.
