System heap

Overview
********

A simple sample that can be used with any :ref:`supported board <boards>` and
prints system heap usage to the console.

Building
********************

This application can be built on native_posix as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/basic/sys_heap
   :host-os: unix
   :board: native_posix
   :goals: build
   :compact:

To build for another board, change "native_posix" above to that board's name.

Running
*******

Run build/zephyr/zephyr.exe
