Where to find the correct Devicetree .dts file for nRF Connect SDK Fundamentals Lesson 2 (section: DK devicetree file)

[NanoJ]

Hiya,

I am currently going through the nRF Connect SDK Fundamentals Lesson 2 (section: DK devicetree file)  and I am stuck. In the example given, it says: 

" These hardware details are all described in the devicetree file for the nRF52833 DK. Let’s examine this file, available in <install_path>\zephyr\boards\nordic\nrf52833dk\nrf52833dk_nrf52833.dts"

Im using the nrf54L15 so I assumed I would perhaps locate the dts file in  <install_path>\zephyr\boards\nordic\nrf54L15dk\nrf54L15dk_nrf54L15.dts

I was partly correct but did not locate the file nrf54L15dk_nrf54L15.dts instead, I found the following DTS files in the folder (hopefully you can see the image):

I opened the DTS files relevant to the nrf54L15dk but none of them looked fully similar to the DTS file of the nrf52833dk snippet example used in the lesson.

Any assistance or clue as to where to locate the nrf54L15dk_nrf54L15.dts would be appreciated as I would like to continue the lesson. 

Or perhaps the file is broken up into multiple files?

Thank you all!

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,

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