address-cells and size-cells are look to be in

nrf52832.dtsi

which is included in the nrf52832_qfaa.dtsi

I'm guessing there are still pathing issues with your environment being able to see #include <nordic/nrf52832_qfaa.dtsi> in your custom .dts file? (i.e. that error still remains)?

(Hence why I queried if nrf52832_qfaa.dtsi and nrf52832.dtsi were in your local drive C:\ncs\v2.4.0\zephyr\dts\arm\nordic, and if that ncs/vMajor.Minor.Patch was your selected sdk in the project settings earlier)

[for reference, piggybacking off your other thread here : Build own custom board on nrf Connect SDK(Devicetree) as well as replies here, I made a custom board called exampleboard, made the dtsi, dts, etc. mostly for addition of uart and usb to get the helloworld working, and was able to flash and see the output, so just trying to figure out what was different between our environments other than the fact I only have a nrf52840DK available so that's the target soc for me.)

For this error,

I notice in one of your images your .dts is a little different syntactically.

all my .dts have that / before the opening

yes my custom booard is in 2.4.0 and my project is set to v2.4.0

RE: Devicetree Peripherals

droidecahedron — Thu, 15 Jun 2023 14:40:08 GMT

Is that in v2.4.0? and is your project set to v2.4.0?

When I try to build an application with this custom board(I make). I get the following error messages:

Yes, it is there

If you path to the directory I show above, is the file there that you're trying to include? (My path is with default sdk directory in my default drive, C:\ncs\v2.4.0\zephyr\dts\arm\nordic)

ok, but however it does not change

Whoops, I just realized it's a nrf52832 and not 52833. My bad.

It is in fact qfaa.dtsi

(for ref : )

You can see it in the following picture

droidecahedron — Thu, 15 Jun 2023 14:09:07 GMT

What's the error there under the nordic/nrf52832_qiaa.dtsi?

RE: Devicetree Peripherals

Tal. — Thu, 15 Jun 2023 14:05:44 GMT

I change it

However it doesnt change anything.

RE: Devicetree Peripherals

droidecahedron — Thu, 15 Jun 2023 14:03:52 GMT

at the top, it's

#include <nordic/nrf52840_qiaa.dtsi>

not qfaa

edit: This is not correct, misunderstood which soc he was working with

Yes I 'include it in my .dts file. I place it in the same folder as the dtsi file( see picture).

However the whole code in .dts is marked as error too.(see picture)

the .dtsi file is marked as error

RE: Devicetree Peripherals

droidecahedron — Thu, 15 Jun 2023 13:35:39 GMT

Where did you place the .dtsi? Where did you name it?

And did you #include it in your .dts?

RE: Devicetree Peripherals

Tal. — Thu, 15 Jun 2023 13:07:28 GMT

than you for your answer. You are rigth I had no .dtsi file in the folder. So I created an .dtsi file an declare i2C and uart.But the whole code is marked as syntax error. Do I have to pay attention to anything else when creating the .dtsi file.

RE: Devicetree Peripherals

droidecahedron — Thu, 15 Jun 2023 12:27:26 GMT

Does your .dtsi expand on uart0_default, and i2c1_default?

like the following

(It's here I usually change which port/pin it is in that NRF_PSEL portion.)
