Device Tree not showing and updating as per my overlay present in the root directory

[Jacky Ortega]

Hi All,

I am using 'NRF SDK v2.7 + NRF5340 DK + VSCode' and cloned a official nrf 'blinky' sample. The code and pins are working fine and I have verified using DK and logic analyzer. My confusion is since, I have defined a nrf5340dk_nrf5340_cpuapp.overlay  in my project root directory and properly selected for 'build configuration' as well but my device-tree is not reflecting/updating as per my new 'nrf5340dk_nrf5340_cpuapp.overlay' file. As you can see even though relays node and pinouts are defined the device-tree is not reflecting them. It is always showing that 'nrf5340dk_nrf5340_cpuapp.dts' are being used and that 'Editing SDK file!' is not a good idea[which is true of course].

My question and need help is that I don't want that to happen I want to show and be in sync with the pinouts as per my 'nrf5340dk_nrf5340_cpuapp.overlay'

Please also see attached my full overlay file. Thank you

Hello,

Looks like there is a typo in your overlay file. Try calling it "nrf5340dk_nrf5340_cpuapp.overlay", delete the build folder and then build it again. It should be picked up.

Or do you mean that you are able to make the compiler pick it up, but the devicetree GUI tool does not pick it up?

Best regards,

Edvin

If it is the Devicetree GUI tool that is the issue, this is apparently a known issue. Please test the suggested versions that I just mentioned in this post:
Problem with the nrf connect for the Visual code.

Best regards,

Edvin

Hi Edvin ,

In my post there was the typo for the .overlay I was using I have corrected it in my post. 
Yes I am able to successfully compile and verify my pinouts on my DK using prints and logic analyzer.
My concern was keeping in view my .overlay the device-tree should be updated/sync with the pinouts used in my overlay, unfortunately it isn't.

Hi Edvin ,

I am using the following extensions for VSCode:

nRF Connect for VS Code = v2024.11.22

nRF DeviceTree = v2024.11.16

Yes. The issue seems similar to Problem with the nrf connect for the Visual code. the link you shared in your above reply.
and also Output pins configured in the Overlay, not showing in Devicetree view

[Edvin]

Ok. In that case, it is a known bug in the nRF DeviceTree extension for VS Code. But it is only in the visual tool. You can still write .overlay files manually. Usually, I just copy the parts that I want to modify from the .dts / .dtsi files, and paste it into the .overlay file, and change the pin numbers etc. in there. So hopefully, until the patch is released, you can either do that, or you can try to downgrade the nRF DeviceTree version.

Best regards,

Edvin
