Finally! I did it! Thank you!
What I did:

1. Used windows 11 pro (bootcamp)

2. Copied new project example - light bulb

3. created configuration (like you said)

4. Connected board to pc

5. opened nRF Connect for Desctop > Serial Terminal > COM6(vcom1) and turned on autodetect lines in config.
6. Erase memory in programmer.
7. Turned on Dev mode in windows:

Settings > Privacy & Security > For Developers > Developer Mode

8. Restart VS Code

9. First Build

10. Flash Using UI (maybe west flash-d)

11. Look at console (Serial Terminal at nrf connect for desktop)

As I know reconnect usb is the same as click RESET. I tried to do everything.
Also I tried to read logs in different programs but no result on Mac and windows.
LED0 didn’t blink. I think I’m doing something wrong.
I seen https://wiki.seeedstudio.com/xiao_nrf54l15_sense_matter/ tutorial. And I tried it.

I noticed that after the terminal stopped working, you disconnected and reconnected the device.
Instead of doing that, please press the RESET button on the DK to restart it.

Also, instead of using the VS Code terminal, try using the serial terminal in nRF Connect for Desktop or a terminal-based tool like picocom.

Make sure to open the terminal before programming the board so that we can capture the logs immediately.

After programming the device:

Verify that LED0 on the board is blinking.

Open the nRF Connect mobile app and perform a BLE scan to check if any BLE device is advertising.

Note:
Please confirm that the same serial terminal works with the Quickstart sample. After flashing the Quickstart sample, check whether the terminal you selected displays logs correctly. If not, switch to a different serial terminal. check the SERIAL PORT is selected in 115200 BAUD RATE

looks strange. I will make a video +-1 minute duration. I hope you will see my mistake (video on YouTube)

RE: nRF54L15-DK Matter Over Thread start

Sunil vignesh — Tue, 07 Oct 2025 13:01:22 GMT

Also in nrf connect for Desktop -> BOARD CONFIGURATOR. open it connect the DK and check all these are ON

Your Merged.hex is worked for me
please check and confirm the LED0 is blinking after merged.hex flashed on the board

RE: nRF54L15-DK Matter Over Thread start

ADM1N — Tue, 07 Oct 2025 11:45:30 GMT

Still nothing. Did you edit config? And could you send me your merged.hex for test?
As I see you using linux. Im using Mac and windows. Can it be a problem?
My merged.hex:

check the build log it seems to be like this

Building light_bulb
west build --build-dir /home/sunmac/office/ncs/works/scrap/light_bulb/build /home/sunmac/office/ncs/works/scrap/light_bulb --pristine --board nrf54l15dk/nrf54l15/cpuapp/ns --sysbuild -- -DCONF_FILE="prj.conf" -DDTC_OVERLAY_FILE=boards/nrf54l15dk_nrf54l15_cpuapp_ns.overlay

and do eraseall the nRF54L15DK board and try to flash the sample, once done, check the VCOM1 COM port and also in DK LED1 is blinking

if it works properly u will get like this

Sorry, my mistake. I mean "Real Matter Over Thread".

I added config like you said. But there is still no logs on VCOM1/0 (UART).
I also tried force torn it on:

# Enable all debug features

CONFIG_USE_SEGGER_RTT=n

CONFIG_SHELL=y

CONFIG_OPENTHREAD_SHELL=y

CONFIG_CONSOLE=y

CONFIG_UART_CONSOLE=y

CONFIG_SERIAL=y

CONFIG_LOG_MODE_MINIMAL=n

CONFIG_ASSERT_VERBOSE=y

CONFIG_ASSERT_NO_FILE_INFO=y

CONFIG_PRINTK=y

CONFIG_PRINTK_SYNC=y

CONFIG_THREAD_NAME=y

Hi,
try to build it with prj.conf and ns.overlay, also check the VCOM1 is connect in board configurator.

nRF54L15 is not a WiFi device , its a Thread device (Matter over Thread will support)

nRF7002 DK will support Matter over Wifi
