i tried reinstalling toolchain and sdk an reinstalled the extension-pack. so far no good.

I will try using adiffrent laptop later.

keeping you updated.

We are not able to recreate the issue and there is nothing that should cause this is the code at first glance. Have you tried reinstalling VS Code/NCS from scratch? Could you try to recreate the environment on a different computer/user profile if possible?

yes i tested the zephyr-adc-sample with a buildconfiguration using the nrf52840DK-Board and the corresponding .overlay-file suggested when i click the dropdown.

The /boards-folder used is in the project-directory with the following scheme:

once again everything blanked is the customername.

i also defined another board root for other projects:
C:/my_boards

so my arch is also arm.

Before updating my extension it worked more or less flawlessly. I had the issue that the visual DT did not update according to my textual representation, but i could live with that.

Have you tested a Nordic sample on a Nordic DK?
Can you confirm that your custom board is located in /boards/{arch}/{board_name}? Also, could you clarify what the {arch} folder is?

In the case below, the parent folder of the board is arm. This tells the devicetree to load the arm include path from the SDK.

I can confirm this is a global issue as its also present after i compiled the adc-sample from zephyr.

Same issue

Thanks,
Just to confirm, are you seeing this issue for this application only or is this a global issue?

so it appears not to find the corresponding chip-level.dtsi-files.

Here are my.dts (once again the customers and project name are substituted):

When importing nordic/nrf52....dtsi there is an error in vscode:

Here is my corresponding .dtsi-file wich is included above:

Here is my DT-overlay:

Thanks Hendrik,

It looks like the board does not have SOC or CPU nodes. Can you confirm these exist?
Does the .dts file include any .dtsi files? If so, could you share the paths where the .dtsi paths are relative to the SDK and application?

H.Marske — Tue, 26 Aug 2025 08:17:06 GMT

The blanked out parts are the project name with customer name wich is currently under NDA. But its all the same and its all the same. my custom board

Best regards,

Hendrik

Hi Hendrik,
Could you please share what you see in the node and file tree view? (Like the pictures below)

Best regards,
