|
|
|
|
********
|
|
|
|
|
|
|
|
|
|
.. note::
|
|
|
|
|
|
|
|
|
|
All software for the nRF54L20 SoC is experimental and hardware availability
|
|
|
|
|
is restricted to the participants in the limited sampling program.
|
|
|
|
|
|
|
|
|
|
The nRF54L20 Preview Development Kit hardware provides
|
|
|
|
|
support for the Nordic Semiconductor nRF54L20 Arm Cortex-M33 CPU and
|
|
|
|
|
the following devices:
|
|
|
|
|
|
|
|
|
|
* CLOCK
|
|
|
|
|
* RRAM
|
|
|
|
|
* :abbr:`GPIO (General Purpose Input Output)`
|
|
|
|
|
* :abbr:`GRTC (Global real-time counter)`
|
|
|
|
|
* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
|
|
|
|
|
* :abbr:`UARTE (Universal asynchronous receiver-transmitter)`

Hardware
|
|
|
|
|
********
|
|
|
|
|
|
|
|
|
|
nRF54L20 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 ``nrf54l20pdk/nrf54l20/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.

As an example, this section shows how to build and flash the :zephyr:code-sample:`hello_world`
|
2024-08-02 21:36:03 +08:00
|
|
|
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 nRF54L20 PDK, complete the following steps:
|
|
|
|
|
|
|
|
|
|
First, connect the nRF54L20 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: nrf54l20pdk/nrf54l20/cpuapp
