Thanks a lot Simon for replying! It does provide the LEDs just as the example.

Hi,

I believe the file you are searching for is "<install_path>\zephyr\boards\nordic\nrf54L15dk\nrf54l15dk_common.dtsi".

The devicetree architecture of the nrf54l15dk is a bit different to the nrf52833dk because nrf54 contains multiple cores. This is also why there are some files with *_cpuapp and *_cpuflrp referring to the "Application CPU" and the "Fast Lightweight Peripheral Processor".

Best regards,

Simon D-M
