Build own custom board on nrf Connect SDK(Devicetree)

[Tal.]

Hello,

hello i have created my own devicetree (.dts) file for a self developed board(nrf52dk_nrf52832_customer) based on the nrf52 chip. So I created an folder( named: nrf52dk_nrf52832_customer)  at the following file path:

 ncs\v2.3.0\zephyr\boards\arm\nrf52dk_nrf52832_customer.

he devicetree can be found at this file path:

How can I now flash an application on the customer board. In Visual Studio Code the board does not appear (see picture), So I can not build the whole thing.

thank 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.

Please take a look at this documentation and see if it helps you.

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?

[Tal.]

Yes, it works with nrf52832DK

[droidecahedron]

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

[Tal.]

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

[droidecahedron]

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, 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

[droidecahedron]

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.
