Programming and Debugging

.. zephyr:board-supported-runners::

Flashing

The sample application :zephyr:code-sample:hello_world is used for this example. Build the Zephyr kernel and application:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: sim3u1xx_dk :goals: build

Connect the sim3u1xx_dk to your host computer using both USB port and you should see a USB serial connection.

Open a serial terminal (minicom, putty, etc.) with the following settings:

  • Speed: 115200
  • Data: 8 bits
  • Parity: None
  • Stop bits: 1

Reset the board and you'll see the following message on the corresponding serial port terminal session:

.. code-block:: console

Hello World! sim3u1xx_dk/sim3u167
