nRF54LS05 DK

Note

You can find more information about the nRF54LS05B SoC on the nRF54LS05B System-on-Chip product page. For the nRF54LS05B technical documentation and other resources (such as the SoC Datasheet), see Developing with nRF54L Series.

nRF54LS05 DK

nRF54LS05 DK

The nRF54LS05 Development Kit hardware provides support for the Nordic Semiconductor nRF54LS05B Arm Cortex-M33 CPU and the following devices:

  • SAADC

  • CLOCK

  • RRAM

  • GPIO

  • TWIM

  • MEMCONF

  • MPU

  • NVIC

  • GRTC

  • Segger RTT (RTT Console)

  • SPI

  • UARTE

  • WDT

Hardware

nRF54LS05 DK has two crystal oscillators:

  • High-frequency 32 MHz crystal oscillator (HFXO)

  • Low-frequency 32.768 kHz crystal oscillator (LFXO)

You can configure the crystal oscillators to use either internal or external capacitors.

Programming and Debugging

You can build, flash, and debug applications for the nrf54ls05dk/nrf54ls05b/cpuapp in the usual way. See Building an Application and Run an Application for more details on building and running.

Flashing

As an example, the following 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. Refer to further information about Flashing.

To build and program the sample to the nRF54LS05 DK, complete the following steps:

  1. Connect, connect the nRF54LS05 DK to your computer using the IMCU USB port on the DK.

  2. Build, build the sample by running the following command:

# From the root of the zephyr repository
west build -b nrf54ls05dk/nrf54ls05b/cpuapp samples/hello_world
west flash
