Overview

Note

You can find more information about the BL54L15u module on the BL54L15u website.

You can find more information about the underlying nRF54L15 SoC on the nRF54L15 website. For the nRF54L15 technical documentation and other resources (such as SoC Datasheet), see the nRF54L15 documentation page.

The BL54L15u Development Kit provides support for the Ezurio BL54L15u module.

The module is based on the Nordic Semiconductor nRF54L15 Arm Cortex-M33 CPU.

The BL54L15u module incorporates the WLCSP package nRF54L15 (1524kB Flash, 256kB RAM). The part features up to 32 configurable GPIOs and BLE Radio TX Power up to 8dBm.

The module includes the following devices:

• SAADC

• CLOCK

• RRAM

• GPIO

• TWIM

• MEMCONF

• MPU

• NVIC

• PWM

• GRTC

• Segger RTT (RTT Console)

• SPI

• UARTE

• WDT

Hardware

The BL54L15u DVK 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 bl54l15u_dvk/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 bl54l15u_dvk/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 bl54l15u_dvk/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 BL54L15u DVK, complete the following steps:

First, connect the BL54L15u DVK to your computer using the IMCU USB port on the DVK. Next, build the sample by running the following command:

# From the root of the zephyr repository
west build -b bl54l15u_dvk/nrf54l15/cpuapp samples/hello_world
west flash

Testing the LEDs and buttons on the BL54L15u DVK

Test the BL54L15u DVK with a Blinky sample.
