+
+Overview
+********
+
+.. note::
+
+   All software for the nRF54L15 SoC is experimental and hardware availability
+   is restricted to the participants in the limited sampling program.
+
+The nRF54L15 Development Kit hardware provides support for the Nordic Semiconductor
+nRF54L15 Arm Cortex-M33 CPU and the following devices:
+
+* :abbr:`SAADC (Successive Approximation Analog to Digital Converter)`
+* CLOCK
+* RRAM
+* :abbr:`GPIO (General Purpose Input Output)`
+* :abbr:`TWIM (I2C-compatible two-wire interface master with EasyDMA)`
+* :abbr:`MPU (Memory Protection Unit)`
+* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
+* :abbr:`PWM (Pulse Width Modulation)`
+* :abbr:`GRTC (Global real-time counter)`
+* Segger RTT (RTT Console)
+* :abbr:`SPI (Serial Peripheral Interface)`
+* :abbr:`UARTE (Universal asynchronous receiver-transmitter)`
+* :abbr:`WDT (Watchdog Timer)`

+
+Hardware
+********
+
+nRF54L15 DK has two crystal oscillators:
+
+* High-frequency 32 MHz crystal oscillator (HFXO)
+* Low-frequency 32.768 kHz crystal oscillator (LFXO)
+
+The crystal oscillators can be configured to use either
+internal or external capacitors.
+

+
+Programming and Debugging
+*************************
+
+Applications for the ``nrf54l15dk/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 ``nrf54l15dk/nrf54l15/cpuflpr`` board target need
+to be build as multicore configuration with code snippet called ``vpr_launcher``
+for the application core.
+
+Enter the following command to compile ``hello_world`` for the FLPR core::
+ west build -p -b nrf54l15pdk/nrf54l15/cpuflpr --sysbuild -- -DSB_VPR_LAUNCHER=y
+
+Flashing
+========
+
+As an example, this section shows how to build and flash the :ref:`hello_world`
+application.
+
+.. 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`.
+
+To build and program the sample to the nRF54L15 DK, complete the following steps:
+
+First, connect the nRF54L15 DK to you computer using the IMCU USB port on the DK.
+Next, build the sample by running the following command:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: nrf54l15dk/nrf54l15/cpuapp
+   :goals: build flash
+
+Testing the LEDs and buttons in the nRF54L15 DK
+************************************************
+
+Test the nRF54L15 DK with a :zephyr:code-sample:`blinky` sample.
