| Overview |
| ******** |
| |
| The QEMU board configuration is used to emulate the Xtensa architecture. This board |
| configuration provides support for the Xtensa simulation environment. |

| Programming and Debugging |
| ************************* |
| |
| Use this configuration to run basic Zephyr applications and kernel tests in the QEMU |
| emulated environment, for example, with the :ref:`synchronization_sample`: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/synchronization |
| :host-os: unix |
| :board: qemu_xtensa |
| :goals: run |
| |
| This will build an image with the synchronization sample app, boot it using |
| QEMU, and display the following console output: |
| |
| .. code-block:: console |
