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 using sysbuild to include the vpr_launcher image for the application core.
Enter the following command to compile hello_world for the FLPR core:
west build -p -b nrf54l15dk/nrf54l15/cpuflpr --sysbuild
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
nRF54L05 emulation on nRF54L15 DK
The nrf54l15dk/nrf54l05 board is a modified version of the nRF54L15 DK
that enforces the limitations imposed by the nRF54L05 IC, which is a
cost-reduced variant of the original nRF54L15. Since Nordic does not offer a
development kit for the nRF54L05, you can use this board to develop for this
IC while using the nRF54L15 Development Kit (PCA10156).
See nRF54L05 website [3] for the official reference on the IC itself.
nRF54L10 emulation on nRF54L15 DK
The nrf54l15dk/nrf54l10 board is a modified version of the nRF54L15 DK
that enforces the limitations imposed by the nRF54L10 IC, which is a
cost-reduced variant of the original nRF54L15. Since Nordic does not offer a
development kit for the nRF54L10 you can use this board to develop for this
IC while using the nRF54L15 Development Kit (PCA10156).
