Intel ISSM
**********

.. note::

The ISSM toolset only supports development for Intel |reg| Quark |trade|
Microcontrollers, for example, the Arduino 101 board. (Check out the
"Zephyr Development Environment
Setup" in this `Getting Started on Arduino 101 with ISSM`_ document.)
Additional setup is required to use the ISSM GUI for development.

#. Install the ISSM toolchain by downloading it from the Intel Developer Zone's
`ISSM Toolchain`_ downloads page, then extracting the archive somewhere on
your system.

.. warning::

Like the Zephyr repository, do not install the toolchain in a directory
with spaces anywhere in the path.

#. :ref:`Set these environment variables <env_vars>`:

- Set :envvar:`ZEPHYR_TOOLCHAIN_VARIANT` to ``issm``.
- Set :envvar:`ISSM_INSTALLATION_PATH` to the directory containing the
extracted files.

#. To check that you have set these variables correctly in your current
environment, follow these example shell sessions (the
:envvar:`ISSM_INSTALLATION_PATH` values may be different on your system):

.. code-block:: console

# Linux
$ echo $ZEPHYR_TOOLCHAIN_VARIANT
issm
$ echo $ISSM_INSTALLATION_PATH
/home/you/Downloads/issm0-toolchain-windows-2017-02-07

# Windows
> echo %ZEPHYR_TOOLCHAIN_VARIANT%
issm
> echo %ISSM_INSTALLATION_PATH%
c:\issm0-toolchain-windows-2017-01-25
