Native Installation (OS X)

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.

Before you start, you will need to add the JuulLabs-OSS/homebrew-mynewt 'tap' to brew, which can be done as

follows:
