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 also available in brew (used to install newt and newtmgr), as described in the setup

guide below:

You can test the installation with the following command (making sure that the version listed is 4.9!):

$ newtmgr help

Newtmgr helps you manage remote devices running the Mynewt OS

Usage:

newtmgr [flags]

newtmgr [command]

Available Commands:

config Read or write a config value on a device

conn Manage newtmgr connection profiles

crash Send a crash command to a device

datetime Manage datetime on a device

echo Send data to a device and display the echoed back data

fs Access files on a device

help Help about any command

image Manage images on a device

log Manage logs on a device

mpstat Read mempool statistics from a device

reset Perform a soft reset of a device

run Run test procedures on a device

stat Read statistics from a device

taskstat Read task statistics from a device

Flags:

-c, --conn string connection profile to use

-h, --help help for newtmgr

-l, --loglevel string log level to use (default "info")

--name string name of target BLE device; overrides profile setting

-t, --timeout float timeout in seconds (partial seconds allowed) (default 10)

-r, --tries int total number of tries in case of timeout (default 1)

Use "newtmgr [command] --help" for more information about a command.
