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 DK is a single-board 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.
  • a Nordic VPR RISC-V core, referred to as the ppr core (Peripheral Processor).

The nrf54h20dk/nrf54h20/cpuapp build target provides support for the application core on the nRF54H20 SoC. The nrf54h20dk/nrf54h20/cpurad build target provides support for the radio core on the nRF54H20 SoC. The nrf54h20dk/nrf54h20/cpuppr build target provides support for the PPR core on the nRF54H20 SoC executing from RAM. The nrf54h20dk/nrf54h20/cpuppr/xip build target provides support for the PPR core on the nRF54H20 SoC executing from MRAM.

Hardware

nRF54H20 DK has two crystal oscillators:

  • High-frequency 32 MHz crystal oscillator (HFXO)
  • Low-frequency 32.768 kHz crystal oscillator (LFXO)

Supported Features

.. zephyr:board-supported-hw::

Connections and IOs

LEDs

  • LED1 (green) = P9.0
  • LED2 (green) = P9.1
  • LED3 (green) = P9.2
  • LED4 (green) = P9.3

Push buttons

  • BUTTON1 = P0.8
  • BUTTON2 = P0.9
  • BUTTON3 = P0.10
  • BUTTON4 = P0.11
  • RESET (SW1)

Programming and Debugging

.. zephyr:board-supported-runners::

.. note:: When first using the nRF54H20 DK, you must program the nRF54H20 SoC binaries_ on the development kit. To do so, follow the bring up steps instructions on the Getting started with the nRF54H20 DK_ documentation.

Applications for all targets can be built and flashed the usual way. See :ref:build_an_application and :ref:application_run for more details on building and running. Debugging is for now limited to the application and radio cores only, using :ref:nordic_segger.

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 nRF54H20 DK, complete the following steps:

  1. Connect the nRF54H20 DK to your computer using the IMCU USB port on the DK.

  2. Install nRF Util_ #. Build the sample by running the following command:

    .. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: nrf54h20dk/nrf54h20/cpuapp :goals: build flash

Testing the LEDs and buttons in the nRF54H20 DK

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/nordic/nrf54h20dk/nrf54h20dk_nrf54h20_cpuapp.dts.
