| 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 PDK 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 ``nrf54l15pdk/nrf54l15/cpuapp`` board 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. |
| |
| 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 PDK, complete the following steps: |
| |
| First, connect the nRF54L15 PDK to you computer using the IMCU USB port on the PDK. |
| Next, build the sample by running the following command: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: nrf54l15pdk/nrf54l15/cpuapp |
| :goals: build flash |
| |
| Testing the LEDs and buttons in the nRF54L15 PDK |
| ************************************************ |
| |
| Test the nRF54L15 PDK with a :zephyr:code-sample:`blinky` sample. |
