nRF54L20 PDK
Overview
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
GPIO
GRTC
NVIC
UARTE
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
Building an Application and Run an Application for more details on
building and running.
Flashing
As an example, this section shows how to build and flash the Hello World application.
Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in 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:
# From the root of the zephyr repository
west build -b nrf54l20pdk/nrf54l20/cpuapp samples/hello_world
west flash
