Flashing Prebuilt Firmware

Requirements

  • Computer with Windows, macOS, or Linux

  • Nordic nRF54L15DK development board

  • 2x USB-C cable

  • 10-pin SWD cable

  • 10-pin SWD breakout adapter

  • 4x 0.1" (2.54mm) pitch leads

  • Nordic nRF Connect for Desktop

Steps

  1. Using the 10-pin SWD cable, connect the "DEBUG OUT" connector on the nRF54L15DK to the SWD breakout adapter.

  2. Using 0.1" (2.54mm) pitch leads, connect the VRef/VCC, SWDIO, SWDCLK, and GND signals from the adapter to the corresponding pins on the bottom left of connector J4 on the ME54BE01.

  3. Using the USB-C cable connect the ME54BE01 to your computer.

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

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

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

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

  8. 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 on connector J4 of the ME54BE01

  2. Connect the TX signal of the serial converter to the pin labeled P1.05 on connector J4 of the ME54BE01

  3. Connect the GND signal of the serial converter to the pin labeled GND on connector J4 of the ME54BE01

  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.
