You have to make sure that the VDD of the nRF52 DK is identical to the voltage of the external nRF52 and make sure that the EXT_VTG on the P19 header(see this post= is connected to the external device VDD.

That is the proper configuration: we are using it here every day.

Just to clarify:

nRF VDD -> VTG -> BOARD VDD

GND DETECT -> NRF52 DK GND -> BOARD GND

That is assuming you want to power your board with the NRF52DK.

I tried this, but it does not help. Nor it work with external powered board as I used it in mentioned test scenarios.

GND detect must be connected to DK52 gnd AND your board gnd also the NRF VDD must be connected to VTG and your board VDD
