nrf52 DK not detected in nrfgo studio

[nodevzo]

Hello,

I'm trying to flash my nrf52 DK but it's not detected by nrfgo studio.

here are the version of the softwares i'm using :

SDK : 14 JLink : 6.20g Command Line tools : 9.7.1 nRFgo Studio : 1.21.2 OS : Windows Server 2016

I already tried different usb cables and differents ports, it does nothing.

The cmd command "nrfjprog" works fine and "nrfjprog --recover" return "ERROR: There is no debugger connected to the PC."

Can you try it on a Windows 7 pc?

Are you sure it is on? The DK's have a power switch.
