nRF54L15 PDK

Overview

Note

All software for the nRF54L15 SoC is experimental and hardware availability is restricted to the participants in the limited sampling program.

The nRF54L15 Preview Development Kit hardware provides support for the Nordic Semiconductor nRF54L15 Arm Cortex-M33 CPU and the following devices:

  • SAADC

  • CLOCK

  • RRAM

  • GPIO

  • TWIM

  • MPU

  • NVIC

  • PWM

  • GRTC

  • Segger RTT (RTT Console)

  • SPI

  • UARTE

  • WDT

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 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.

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 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 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:

# From the root of the zephyr repository
west build -b nrf54l15pdk_nrf54l15_cpuapp samples/hello_world
west flash

Testing the LEDs and buttons in the nRF54L15 PDK

Test the nRF54L15 PDK with a Blinky sample.
