How to modify device tree for a custom board

[r0n9]

Good evening,

I am working on a project using a customized board with nrf52840. The project is built on MBed. I am trying to switch to nRF Connect SDK. The first step is to create DT for the customized board. I searched across the forum and found the following resources

 Modifying the device tree for a custom board 

and

They are based on nRFConnectSDK 1.4 and 1.5. Now the version is 2.6.0. I wonder if there are any new tutorials/references related to the device tree configuration topic.

Thanks for your help

I am not sure why they removed this sample out of the latest versions of Zephyr, but thankfully they still have their 3.1 branch. Anyway, here is the sample I followed to create our custom board based off of the nRF52840 SoC. There have been a few minor tweaks to the DTS since this version, but this should still be relevant and give you what you need:

Circuit Dojo has a video on it as well that may help:

Hi, 

You can take a look at the DevAcademy’s courses nRF Connect SDK Intermediate Lesson 3 – Adding custom board support

Due to the Easter holidays in Norway, we are less staffed than usual. You can expect a delayed answer. Sorry for the inconvenience and thanks for your patience.
