nRF54L15 DK
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 Development Kit hardware provides support for the Nordic Semiconductor nRF54L15 Arm Cortex-M33 CPU and the following devices:
SAADC
CLOCK
RRAM
GPIO
TWIM
MEMCONF
MPU
NVIC
PWM
GRTC
Segger RTT (RTT Console)
SPI
UARTE
WDT

Hardware
nRF54L15 DK 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 nrf54l15dk/nrf54l15/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.
Applications for the nrf54l15dk/nrf54l15/cpuflpr board target need
to be built as multicore configuration with code snippet called vpr_launcher
for the application core.
- Enter the following command to compile
hello_worldfor the FLPR core:: west build -p -b nrf54l15dk/nrf54l15/cpuflpr –sysbuild – -DSB_VPR_LAUNCHER=y
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 DK, complete the following steps:
First, connect the nRF54L15 DK to you computer using the IMCU USB port on the DK. Next, build the sample by running the following command:
# From the root of the zephyr repository
west build -b nrf54l15dk/nrf54l15/cpuapp samples/hello_world
west flash
