Arm linux toolchain windows

Installing the Cross Tools for ARM¶

This page shows you how to install the tools to build, run, and debug Mynewt OS applications that run on supported ARM target boards. It shows you how to install the following tools on Mac OS, Linux and Windows:

ARM cross toolchain to compile and build Mynewt applications for the target boards.

Debuggers to load and debug applications on the target boards.

Installing the ARM Cross Toolchain¶

ARM maintains a pre-built GNU toolchain with gcc and gdb targeted at Embedded ARM Processors, namely Cortex-R/Cortex-M processor families. Mynewt OS has been tested with version 4.9 of the toolchain and we recommend you install this version to get started. Mynewt OS will eventually work with multiple versions available, including the latest releases.

Installing the ARM Toolchain For Mac OS X¶

Add the PX4/homebrew-px4 homebrew tap and install version 4.9 of the toolchain. After installing, check that the symbolic link that homebrew created points to the correct version of the debugger.

Note: If no version is specified, brew will install the latest version available.

Installing the ARM Toolchain For Linux¶

On a Debian-based Linux distribution, gcc 4.9.3 for ARM can be installed with apt-get as documented below. The steps are explained in depth at https://launchpad.net/

Installing the ARM Toolchain for Windows¶

Download and run the installer to install arm-none-eabi-gcc and arm-none-eabi-gdb. Select the default destination folder: C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2020-q4-major.

Notes:

Check the Add path to environment variable option before you click the Finish button for the installation.

You may select a different folder but the installation instructions use the default values.

Check that you are using the installed versions arm-none-eabi-gcc and arm-none-eabi-gdb. Open a MinGW terminal and run the which commands.

Note: You must start a new MinGW terminal to inherit the new Path values.

Installing the Debuggers¶

Mynewt uses, depending on the board, either the OpenOCD or SEGGER J-Link debuggers.

Installing the OpenOCD Debugger¶

OpenOCD (Open On-Chip Debugger) is open-source software that allows your computer to interface with the JTAG debug connector on a variety of boards. A JTAG connection lets you debug and test embedded target devices. For more on OpenOCD go to http://openocd.org.

OpenOCD version 0.10.0 with nrf52 support is required. A binary for this version is available to download for Mac OS, Linux, and Windows.

Installing OpenOCD on Mac OS¶

Install latest OpenOCD from Homebrew:

Check the OpenOCD version you are using:

You should see version: 0.10.0+dev- .

Installing OpenOCD on Linux¶

Change to the root directory:

Untar the tarball and install into /usr/local/bin. You will need to replace

/Downloads with the directory that the tarball is downloaded to.

Note: You must specify the -p option for the tar command.

Check the OpenOCD version you are using:

You should see version: 0.10.0.

If you see any of these error messages:

openocd: error while loading shared libraries: libhidapi-hidraw.so.0: cannot open shared object file: No such file or directory

openocd: error while loading shared libraries: libusb-1.0.so.0: cannot open shared object file: No such file or directory

run the following command to install the libraries:

Installing OpenOCD on Windows¶

Extract into the C:\openocd-0.10.0 folder.

Add the path: C:\openocd-0.10.0\bin to your Windows User Path environment variable. Note: You must add bin to the path.

Check the OpenOCD version you are using. Open a new MinGW terminal and run the following commands:

Note: You must start a new MinGW terminal to inherit the new Path values.

You should see version: 0.10.0.

Installing SEGGER J-Link¶

You can download and install Segger J-LINK Software and documentation pack from SEGGER.

Note: On Windows, perform the following after the installation:

Add the installation destination folder path to your Windows user Path environment variable. You do not need to add bin to the path.

Open a new MinGW terminal to inherit the new Path values.

8.3-2019.03

The GNU Toolchain for the Cortex-A Family is a ready-to-use, open source suite of tools for C, C++ and Assembly programming. This toolchain targets processors from the Arm Cortex-A family and implements the Arm A-profile architecture.

The toolchain includes the GNU Compiler (GCC) and is available free of charge directly for Windows and Linux operating systems. Follow the links on this page to download the correct version for your development environment.

See the downloaded package Release Notes, which are linked from this page, for full installation instructions.

• Spectre v1 mitigation backport from upstream FSF trunk include the revisions listed below. This is an initial backport of those mitigations in the GNU toolchain and should be regarded as support for prototyping and early access only. Moreover, while the backports include support for the other architectures, they are included for completeness and all issues regarding these patches must be taken up upstream in the https://gcc.gnu.org/bugzilla by reproducing the same with upstream FSF trunk. Arm is interested in feedback regarding these workarounds for Spectre v1. A description of the mitigation has been published on LWN.net.

Building toolchain from source

You can build GNU cross-toolchain for the A-profile from sources using Linaro ABE (Advanced Build Environment) and provided ABE manifest files.

Below example shows how to build gcc-arm-aarch64-linux-gnu toolchain from sources using Linaro ABE build system.

Instructions

Clone ABE one of the URL below and checkout the stable branch (see Getting ABE):

Create the build directory and change to it. Any name for the directory will work (see Building Toolchains With ABE):

Configure ABE (from the build directory):

And finally build toolchain (from the build directory):

Known issues

• Spectre v1 mitigations are provided here for early access and thus might have stability issues. On AArch32 we are currently aware of one issue as documented at PR86951.
• GDB’s Python support requires Python compiled with UCS-4 support (built with —enable-unicode=ucs4) for both hosts x86_64 and i686-mingw32.
• GDB’s Python support requires Python DLL dependencies for i686-mingw32 host.
• Toolchains dedicated for i686-mingw32 host require mingw-w64 library, a complete runtime environment for GCC.

Ask questions

For any questions, please use the Arm Communities forums.

Report bugs

Please report any bugs via the Linaro Bugzilla.
