Datasheet

Native Installation (Linux)

Mynewt relies on two command line utilities ( newt and newtmgr ), both of which are described elsewhere in this

learning guide, as well as the presence of an ARM cross-compiling toolchain ( arm-none-eabi-gcc , etc.).

Both of these need to be installed and available on your system to work with Mynewt projects.

Install newt and newtmgr Binaries

Binary versions of the command-line tools are available from Apache.

The full setup guide is available

here: https://mynewt.apache.org/latest/newt/install/newt_linux.html (https://adafru.it/Erq)

In summary, copy following commands and paste it (one line each time) into your terminal to add newt's public key and

deb package to your apt repository for installation.

Check your installation with version command

Install an ARM Cross-Compiling Toolchain

In order to build and debug ARM binaries, you will also need to install a cross-compiling toolchain targeting the ARM

architecture.

Thankfully, pre-built binaries are available, as described in the setup guide below:

Optional: Install the OpenOCD Debugger (Segger J-Link)

If you wish to debug or flash your projects with a Segger J-Link, you will also need to install the OpenOCD debug tool

via the following steps:

$ wget -qO - https://raw.githubusercontent.com/JuulLabs-OSS/debian-mynewt/master/mynewt.gpg.key | sudo apt-key add -

$ sudo tee /etc/apt/sources.list.d/mynewt.list <<EOF

deb https://raw.githubusercontent.com/JuulLabs-OSS/debian-mynewt/master latest main
