| Overview |
| ******** |
| |
| .. note:: |
| |
| All software for the nRF54H20 SoC is experimental and hardware availability |
| is restricted to the participants in the limited sampling program. |
| |
| The nRF54H20 PDK is a single-board preview development kit for evaluation |
| and development on the Nordic nRF54H20 System-on-Chip (SoC). |
| |
| The nRF54H20 is a multicore SoC with: |
| |
| * an Arm Cortex-M33 core with DSP instructions, FPU, and Armv8-M Security |
| Extensions, running at up to 320 MHz, referred to as the **application core** |
| * an Arm Cortex-M33 core with DSP instructions, FPU, and Armv8-M Security |
| Extensions, running at up to 256 MHz, referred to as the **radio core**. |
| |
| The ``nrf54h20pdk_nrf54h20_cpuapp`` build target provides support for |
| the application core on the nRF54H20 SoC. |
| The ``nrf54h20pdk_nrf54h20_cpurad`` build target provides support for |
| the radio core on the nRF54H20 SoC. |
| |
| nRF54H20 SoC provides support for the following devices: |
| |
| * :abbr:`ADC (Analog to Digital Converter)` |
| * CLOCK |
| * :abbr:`GPIO (General Purpose Input Output)` |
| * :abbr:`GPIOTE (General Purpose Input Output tasks and events)` |
| * :abbr:`GRTC (Global real-time counter)` |
| * :abbr:`I2C (Inter-Integrated Circuit)` |
| * MRAM |
| * :abbr:`PWM (Pulse Width Modulation)` |
| * RADIO (Bluetooth Low Energy and 802.15.4) |
| * :abbr:`SPI (Serial Peripheral Interface)` |
| * :abbr:`UART (Universal asynchronous receiver-transmitter)` |
| * :abbr:`USB (Universal Serial Bus)` |
| * :abbr:`WDT (Watchdog Timer)` |

| Hardware |
| ******** |
| |
| nRF54H20 PDK has two crystal oscillators: |
| |
| * High-frequency 32 MHz crystal oscillator (HFXO) |
| * Low-frequency 32.768 kHz crystal oscillator (LFXO) |

| Programming and Debugging |
| ************************* |
| |
| Applications for both the ``nrf54h20pdk_nrf54h20_cpuapp`` and |
| ``nrf54h20pdk_nrf54h20_cpurad`` targets 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. |
| |
| 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 nRF54H20 PDK, complete the following steps: |
| |
| First, connect the nRF54H20 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: nrf54h20pdk_nrf54h20_cpuapp |
| :goals: build flash |
| |
| Testing the LEDs and buttons in the nRF54H20 PDK |
| ************************************************ |
| |
| There are 2 samples that allow you to test that the buttons (switches) and LEDs |
| on the board are working properly with Zephyr: |
| |
| * :zephyr:code-sample:`blinky` |
| * :zephyr:code-sample:`button` |
| |
| You can build and flash the examples to make sure Zephyr is running correctly on |
| your board. The button and LED definitions can be found in |
| :zephyr_file:`boards/arm/nrf54h20pdk_nrf54h20/nrf54h20pdk_nrf54h20_cpuapp.dts`. |
