Flashing Prebuilt Firmware

Requirements

• Computer with Windows, macOS, or Linux

• Nordic nRF54L15DK

• 2x USB Type C cable to connect your nRF54L15DK and AN54L15Q-DB boards

• 10-pin SWD cable to connect the two boards together

Steps

1. Using the 10-pin SWD cable, connect the "DEBUG OUT" connector on the nRF54L15DK to the "DEBUG IN" connector on the AN54L15Q-DB

2. Using the USB-C cable connect the AN54L15Q-DB to your computer.

3. Using the USB-C cable connect the nRF54L15DK to your computer and turn on the board.

4. Start the nRF Connect for Desktop app and select the Programmer tool.

5. Click the Blue "Select Device" dropdown in the top-left of the Programmer tool and select the "nRF54L15 DK" device

6. In the "File" section of the sidebar, click the "Add File" button and select "Browse...", then select the firmware you wish to flash.

7. In the "Device" section of the sidebar, click the "Erase and write" button to program the firmware

Connecting to UART

You will need a USB to TTL serial converter such as one using an CP210x or FT232RL chip to connect to the module's UART.

1. Connect the RX signal of the serial converter to the pin labeled P1.04/TX on connector J14 of the AN54L15Q-DB

2. Connect the TX signal of the serial converter to the pin labeled P1.05/RX on connector J14 of the AN54L15Q-DB

3. Connect the GND signal of the serial converter to the pin labeled GND on connector J14 of the AN54L15Q-DB

4. Connect a USB cable from the USB to serial converter to your computer and an interface will appear

Depending on the specific converter you use:

• On Windows this interface is usually named COMxx.

• On Mac this interface is usually named /dev/tty.usbserial-XXXXXXXXXXX or /dev/tty.usbmodemxxxxxxxxxxx

• On Linux this port is usually named /dev/ttyUSBx or /dev/ttyACMx.

Develop With this Board in Zephyr

You will first need to set up Zephyr and initialise a workspace for the Blecon Device SDK

The board target for the AN54L15Q-DB is: raytac_an54l15q_db/nrf54l15/cpuapp

Sample command for building and flashing the Devboard Demo Application:

west build -p -b raytac_an54l15q_db/nrf54l15/cpuapp -s blecon-device-sdk/examples/zephyr/devboard-demo
west flash
