Install Arm GNU Toolchain on Ubuntu 22.04

The Arm GNU toolchain (previously known as GNU Arm Embedded toolchain) is a collection of packages such as GCC (GNU Compiler Collection), Binutils, GDB, and other. It is used for embedded systems software development. This toolchain targets the 32-bit ARM Cortex-A, ARM Cortex-M, and ARN Cortex-R processor families.

This tutorial shows how to install Arm GNU toolchain on Ubuntu 20.04.

Install toolchain

There is no straightforward way to determine the latest version of toolchain via command line. So download web page and extract the latest version of toolchain as follows:

ARM_TOOLCHAIN_VERSION=$(curl -s https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads | grep -Po '
Version \K.+(?=
)')

Next, download archive file from official website:

curl -Lo gcc-arm-none-eabi.tar.xz "https://developer.arm.com/-/media/Files/downloads/gnu/$/binrel/arm-gnu-toolchain-$-x86_64-arm-none-eabi.tar.xz"

Create a new directory to store toolchain files:

sudo mkdir /opt/gcc-arm-none-eabi

Extract toolchain files to specified directory:

sudo tar xf gcc-arm-none-eabi.tar.xz --strip-components=1 -C /opt/gcc-arm-none-eabi

Add /opt/gcc-arm-none-eabi/bin directory to the PATH environment variable.

echo 'export PATH=$PATH:/opt/gcc-arm-none-eabi/bin' | sudo tee -a /etc/profile.d/gcc-arm-none-eabi.sh

To make changes to take effect, logout and login to your system or run the following command to apply the changes immediately:

We can check version of compilers:

Remove unnecessary archive file:

rm -rf gcc-arm-none-eabi.tar.xz

Testing toolchain

arm-none-eabi-gcc --specs=rdimon.specs main.c -o test

The file command can be used to verify that executable file is for ARM architecture.

test: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, with debug_info, not stripped

Uninstall toolchain

If you want to completely remove GNU Arm Embedded toolchain, delete the installation directory:

sudo rm -rf /opt/gcc-arm-none-eabi

Remove gcc-arm-none-eabi.sh file that is used to set environment variable:

sudo rm -rf /etc/profile.d/gcc-arm-none-eabi.sh

GNU Debugger (GDB) dependencies

Read this section if you want to use GNU Debugger (GDB). It requires installing additional dependencies.

arm-none-eabi-gdb: error while loading shared libraries: libncursesw.so.5: cannot open shared object file: No such file or directory

Then install libncursesw5 package:

sudo apt install -y libncursesw5

• On Linux, Arm GNU toolchain provides GDB with Python support. It requires installation of Python 3.8. If you are receiving an error regarding Python, such as:

Could not find platform independent libraries Could not find platform dependent libraries Consider setting $PYTHONHOME to [:] Python path configuration: PYTHONHOME = (not set) PYTHONPATH = (not set) . Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding Python runtime state: core initialized ModuleNotFoundError: No module named 'encodings'

Then install Python 3.8 using the separate post. See section «Install older versions».

When installation finished, check GDB version:

If everything installed successfully, you will get output similar to the following:

GNU gdb (Arm GNU Toolchain 12.2.MPACBTI-Bet1 (Build arm-12-mpacbti.16)) 13.0.50.20220406-git Copyright (C) 2022 Free Software Foundation, Inc.

sudo mkdir /opt/gcc-arm-none-eabi
Can I change directory this extract file to the Home folder and PATH environment variable in this folder without any error??
Thank you so much for your help

There are no requirements for installation directory. So, you can extract archive file to home directory and set corresponding PATH environment variable.

You are doing a bit more than only extend the PATH variable.
You are echoing the command to extend the PATH variable onto stdin then capture it via tee and put it (append it) into a file called gcc-arm-none-eabi.sh which resides in the path /etc/profile.d/. This enables you to have the PATH variable dynamically set on each system boot up by the system’s profile mechanism.

Thanks for this tutorial. It helped me install one of ARM’s toolchains on GitHub Actions. Wanted to show my appreciation. Will be checking out more of your content. Cheers.

It seems that you need additional step: to «export ARM_TOOLCHAIN_VERSION=12.2.Rel1» or whatever version.
Thanks for the very detailed steps.

Hi,
The tutorial provides a command which downloads the web page, extracts the latest version of toolchain and assigns version to the ARM_TOOLCHAIN_VERSION variable. Of course, version can be specified manually like you did.

Hi, can I ask a question?
This toolchain is used to developing apps on arm, right? I will not build again?
Thanks!

Hi,
Arm GNU Toolchain is a collection of tools that are used to create applications for ARM-based devices such as Raspberry Pi. Once you have built your application using the toolchain, you can run it on your ARM-based device.

Hi! This article really helped me today. thanks for sharing! any tips on how to configure vscode to do gdb debugging on ARM embedded code?

Hi,
I’m glad to hear that the article assisted you in setting up the Arm GNU Toolchain on your system. Visual Studio Code offers a range of extensions designed to enhance the debugging capabilities for embedded systems based on ARM Cortex-M. To access these extensions, you can explore the official Visual Studio marketplace, where you’ll find a selection of options. Take the time to review the descriptions of each extension to understand how to configure and utilize the debugging features effectively.

2.3.5. Linux – Установка GCC ARM Embedded

Следующим шагом в настройке инструментария является установка пакета GCC для микроконтроллеров ARM Cortex-M и Cortex-R. Это набор инструментов (препроцессор макросов, компилятор, ассемблер, компоновщик и отладчик), предназначенный для кросс-компиляции кода, который мы создадим для платформы STM32.

Последнюю версию GCC ARM можно загрузить с ARM Developer 26 . На момент написания данной главы последняя доступная версия – 6.0. Тарбол Linux можно скачать в разделе загрузки 27 .

После завершения загрузки извлеките пакет .tar.bz2 из /STM32Toolchain .

Извлеченная папка по умолчанию называется gcc-arm-none-eabi-6-2017-q2-up- date . Это не удобно, потому что когда GCC обновляется до более новой версии, нам нужно изменять настройки для каждого созданного проекта Eclipse. Итак, переименуйте ее просто в gcc-arm .

2.3.6. Linux – Установка драйверов Nucleo

Внимательно прочитайте данный пункт. Не пропускайте этот шаг!

В Linux нам не нужно устанавливать драйверы Nucleo от ST, но нам нужно установить с помощью следующей команды:

$ sudo apt-get install libusb-1.0

2.3.6.1.Linux – Обновление микропрограммного обеспечения ST-LINK

Внимательно прочитайте данный пункт. Не пропускайте этот шаг!

Я купил несколько плат Nucleo и увидел, что все платы поставляются со старым микропрограммным обеспечением ST-LINK. Чтобы использовать Nucleo с OpenOCD, необходимо обновить микропрограммное обеспечение как минимум до версии 2.29.18.

Мы можем загрузить последние версии драйверов ST-LINK с веб-сайта ST 28 . Микропрограмма распространяется в виде ZIP-файла. Распакуйте его в удобном месте. Подключите плату Nucleo с помощью USB-кабеля, перейдите во вложенную папку AllPlatforms и выполните файл STLinkUpgrade.jar . Нажмите кнопку Open in update mode (см. рисунок 20).

GNU MCU Eclipse ARM Embedded GCC

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.

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.

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

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.

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).

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.

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.

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.

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.

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.

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.
