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 macOS, Linux and Windows:
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 7.2 of the toolchain and we recommend you install 7.0 or later to get started. Mynewt OS will eventually work with multiple versions available, including the latest releases.
Add the PX4/homebrew-px4 homebrew tap and install version 7.2 of the toolchain. After installing, check that the symbolic link that homebrew created points to the correct version of the debugger.
$ brew tap PX4/homebrew-px4 $ brew update $ brew install gcc-arm-none-eabi-74 $ arm-none-eabi-gcc --version arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 7-2017-q4-major) 7.2.1 20170904 (release) [ARM/embedded-7-branch revision 255204] Copyright (C) 2017 Free Software Foundation, Inc. This is free software; see the source for copying conditions.

Note: If no version is specified, brew will install the latest version available.
On a Debian-based Linux distribution, gcc 7 for ARM can be installed with apt-get as documented below. The steps are explained in depth at https://launchpad.net/~team-gcc-arm-embedded/+archive/ubuntu/ppa.
$ sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi $ sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa $ sudo apt-get update $ sudo apt-get install gcc-arm-embedded
Notes:
Add path to environment variable option before you click the Finish button for the installation.Step 2: 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.
$ which arm-none-eabi-gcc /c/Program Files (x86)/GNU Tools Arm Embedded/7 2018-q2-update/bin/arm-none-eabi-gcc $ which arm-none-eabi-gdb /c/Program Files (x86)/GNU Tools Arm Embedded/7 2018-q2-update/bin/arm-none-eabi-gdb
Mynewt uses, depending on the board, either the OpenOCD or SEGGER J-Link debuggers.
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.
Step 2: Change to the root directory:
$cd /
$which openocd /usr/local/bin/openocd $openocd -v Open On-Chip Debugger 0.10.0 Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html
You should see version: 0.10.0.
If you see one of these errors:
brew install libusb-compat.brew install libftdi.brew install hidapi.Step 2: Change to the root directory:
$cd /
** Note:** You must specify the -p option for the tar command.
$sudo tar -xpf ~/Downloads/openocd-bin-0.10.0-Linux.tgz
$which openocd /usr/local/bin/openocd $openocd -v Open On-Chip Debugger 0.10.0 Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html
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:
$sudo apt-get install libhidapi-dev:i386
Step 2: Extract into the C:\openocd-0.10.0 folder.
Step 3: Add the path: ** C:\openocd-0.10.0\bin** to your Windows User Path environment variable. Note: You must add bin to the path.
Step 4: 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.
$which openocd /c/openocd-0.10.0/bin/openocd $openocd -v Open On-Chip Debugger 0.10.0 Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html
You should see version: 0.10.0.
Note: On Windows, perform the following additonal steps:
