If you're using .dts and .dtsi for the nrf52833dk, it will use those files.

you can use an overlay file if you want to change some stuff around, but if your board is sufficiently custom then you should be using that custom board.

Ok, now I create a board like you described earlier. But I only add the changed dts file and dtsi file to the project(application) folder and I build the application with the nordic board nrf52832DK (from nrf Connect SDK). it works this way. But my question is: the dts and dtsi files from the nrf5832dk will be overwritten with the dts and dtsi files in the project (application folder)?

and I also ttry to create a custom board like you described it earlier. But I dont change any file in the custom board and it also works this way

Potentially.

If I recall in the ticket I linked above (Link again for ref : Devicetree Peripherals)

my last response was the latest I knew of what was going on with your custom board situation.

(and like I iterated there, I followed the gui to create a custom board and set up a .dts to add usb/uart in order to get hello world to print, and I did get it printing.)

Ok, you think I make mistake with configuration of my .dts file?

Sounds like the issue is with your setup of the custom board, that narrows it down a bit.

Yes, it works with nrf52832DK

Can you try building it for a nrf52832DK really quick to determine if its specific to your custom board stuff?

i.e. make a new build config

for the nordic devkit of your target soc, do you get the same errors?

I think it is also related to Devicetree Peropherals

Is this duplicate to Devicetree Peripherals ?

I remove and rebuild the application and I now I get the following error messages:

There is an error message that there is expexted an / in .dts file. However I add it. But the error message stilll remains

thank you for your answer. However I get the following error, when I tried to build an aplication with my custom board.

For starters, in that error message I'm noticing that it says v2.3.0, but the SDK selected in your screenshot of the gui is pathing to v2.4.0

Make sure you click the "Open welcome page" and change the SDK to the one you're trying to use, or change it in the extension settings of VS code.

~~~~

That aside, I'll walk through the process of custom board -> application with screenshots of the GUI.

After you've created the new board, in the same menu is a "create new application"

This is where you can choose from samples or whatnot. For now, let's just use blinky.

I created a custom board in the same process you have (via vscode gui) named exampleboard.

I tick "freestanding," for the SDK/NRF Connect toolchain I use v2.4.0 since that's the version you're on, and here I just choose hello world sample as a template for the application. (Note: You could certainly choose blinky, but blinky requires some device tree updates since your custom device tree won't have any i/o to add the LED)

After creating it, you'll see it under the applications section on the left hand side beneath where you have the "Welcome" menu options.

You'll notice under the application you just created it says "No build configurations"

from here, you can click to create it, and create a build configuration for the custom board you've created.

You can either choose "custom boards" or "all boards" and filter for the board you want.

From here you can click "build configuration"

Now it will start building for the board you've selected. The first build (and any pristine build) can take a little bit, keep an eye on your nRF Terminal outputs to see it progressing.

(Here is my terminal output for reference)

Now, I plug in my board, and flash it with the "ACTIONS" menu

and there we go.

(Note: If you want the uart output, you've gotta update your .dts with some of the uart features. Recommend looking at the nRF52840DK device tree as a sample. Your custom board .dts is, for the most part, quite empty, so you need to update it. Here's a link for some background on device tree : https://docs.zephyrproject.org/3.2.0/build/dts/intro.html)

Also, as a heads up, don't neglect your prj.conf

hank you for your answer. I tried it with the video. However it dosnt work. When I want to build it with the west build commands.The following error appears:

I did some research and found out that you can also create custom boards with VS Studio code. Is there maybe an instruction or something like that, how I have to proceed exactly here. I have tried it via the Create a new board button to proceed (see picture). After I have then clicked on Create Board a board file is created. But how can I now build an application.

Make sure you choose the button for "all boards" hidden behind that dropdown.

Since you placed the board in ncs/v2.3.0, make sure ncs v2.3.0 is your selected ncs version in the vscode settings. (Visible on the home screen)

There are also a few more files if I recall correctly you need in the custom board folder aside from the .dts, but it's been a long while since I made the custom board

Here's a really handy video that I used to make a custom board for customer: www.youtube.com/watch
