.. zephyr:board:: ophelia4ev

Overview

.. note:: You can find more information about the nRF54L15 SoC on the nRF54L15 website. For the nRF54L15 technical documentation and other resources (such as SoC Datasheet), see the nRF54L15 documentation page.

The OPHELIA-IV EV board is an evaluation board of the Ophelia-IV radio module.

Hardware

The Ophelia-IV uses the internal low frequency RC oscillator and provides the so called smart antenna connection, that allows to choose between the module's integrated PCB antenna and an external antenna that can be connected to the available SMA connector.

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the ophelia4ev/nrf54l15/cpuapp board target can be built, flashed, and debugged in the usual way. See :ref:build_an_application and :ref:application_run for more details on building and running.

Applications for the ophelia4ev/nrf54l15/cpuflpr board target need to be built using sysbuild to include the vpr_launcher image for the application core.

Enter the following command to compile hello_world for the FLPR core:

.. code-block:: console

west build -p -b ophelia4ev/nrf54l15/cpuflpr --sysbuild

Flashing

As an example, this section shows how to build and flash the :zephyr:code-sample:hello_world application.

To build and program the sample to the OPHELIA-IV EV, complete the following steps:

First, connect the OPHELIA-IV EV to you computer using the USB port on the board. Then connect a segger flasher to the SWD connector available on the board. Next, build the sample by running the following command:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: ophelia4ev/nrf54l15/cpuapp :goals: build flash

.. warning::

When programming the device, you might get an error similar to the following message::

ERROR: The operation attempted is unavailable due to readback protection in
ERROR: your device. Please use --recover to unlock the device.

This error occurs when readback protection is enabled. To disable the readback protection, you must recover your device.

Enter the following command to recover the core::

west flash --recover

The --recover command erases the flash memory and then writes a small binary into the recovered flash memory. This binary prevents the readback protection from enabling itself again after a pin reset or power cycle.

Follow the instructions in the :ref:nordic_segger page to install and configure all the necessary software. Further information can be found in :ref:nordic_segger_flashing.
