Programming and Debugging
*************************

The ADI SDP-K1 be programmed over USB using the DAPLink firmware running on an
embedded NXP Freescale microcontroller or a 10-pin ``DEBUG`` header connected
to a STLINK debugger.

DAPLink exposes a storage device, as well as USB HID and CDC Endpoints, to the
host. For more details please refer to the `Official DAPLink website`_.

Flashing
========

Flashing an application with a STLINK debugger
----------------------------------------------

First, connect the STLINK debugger to your host computer using the Micro-USB port.
Then attach the debugger to the 10-pin ``DEBUG`` header on the SDP-K1. Finally
connect the SDP-K1 to your host computer using the USB-C port.

Run a serial host program to connect with your board:

.. code-block:: console

   $ minicom -D /dev/serial/by-id/usb-ARM_DAPLink_CMSIS-DAP_<...>

Here is an example for the :ref:`hello_world` application.

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: adi_sdp_k1
   :goals: build flash

You should see the following message on the console:

.. code-block:: console

   Hello World! adi_sdp_k1
