System Clock
The DA14695 Development Kit USB is configured to use the 32 MHz external oscillator on the board.
Connections and IOs
The DA14695 Development Kit USB has one LED and one push button which can be used by applications. The UART is connected to on-board serial converter and accessible via USB1 port on motherboard.
The pin connections are as follows:
LED (red), = P1.01
BUTTON, labeled k1 = P0.06
UART RX, connected to J-Link serial = P0.08
UART TX, connected to J-Link serial = P0.09
System requirements
Prerequisites
Renesas HAL requires Bluetooth controller binary blobs in order to work. Run the command below to retrieve those files.
west blobs fetch hal_renesas
Note
It is recommended running the command above after west update.
Programming and Debugging
The da14695_dk_usb board supports the runners and associated west commands listed below.

Applications for the da14695_dk_usb board configuration can be
built, flashed, and debugged in the usual way. See
Building an Application and Run an Application for more details on
building and running.
Flashing
The DA14695 boots from an external flash connected to QSPI interface. The image written to flash has to have proper header prepended. The process is simplified by using dedicated eZFlashCLI [3] tool that takes care of writing header and can handle different types of flash chips connected to DA1469x MCU. Follow instructions on ezFlashCLI [3] to install the tool. Once installed, flashing can be done in the usual way.

Debugging
The DA14695 Development Kit USB includes a J-Link [2] adaptor built-in which provides both debugging interface and serial port. Application can be debugged in the usual way once DA14695 Development Kit USB is connected to PC via USB.
