I would recommend that you change this in the overlay in your application rather then changing the dts for the 52dk. In general we always recommend that you create a custom board target that matches the HW for your board, as the mentioned DK might have different components then your board

Thank you for the response Runar.

nRF Connect SDK 3.2.4
nRF Connect SDK Toolchain 3.2.4
openOCD 0.12.0
ST-Link V2

I finally managed to get a working solution, as far as I've tested. You are quite correct in your response in changing the regulator mode from DC/DC to LDO, a step which I thought I had completed by implementing it in the board overlay. I will try and link some of the sources that helped. As seen in Picture 1, I created a board overlay specific to my current hardware, cleaned and rebuilt but still got the same bahaviour. Harvey.Zhang in another similar thread with an nRF52840 ( My nRF52840 Module keeps resetting after I changing the mode to LDO ) experienced a similar issue in which he solved it by also changing the regulator code in the .dts file.

Picture 1

I found the same .dts file with my specific board in the device tree and also changed the regulator to LDO (Picture 2)

Picture 2

Also important to note is that the module I am using does not have the components to support DC/DC, so it would be best to change to LDO to prevent any further damage before flashing you firmware. There are several unpopulated areas (Picture 3) which I hope will not affect BLE function.

Does your board use LDO as you have disabled DC/DC?
If so try to enable it the following way

&reg { regulator-initial-mode = <NRF5X_REG_MODE_LDO>; };

Which version of NCS are you using?
in general our DK have a number of Kconfig set in the boards files to match the DK which might not be a valid configuration if your using the dk a bord target for your application
