Hello,

Could you provide more information on how you are trying to program the Development Kit? Which application are you trying to flash into the DK, and which application is currently running on it? Is this a new Development Kit?

If you are new to Nordic devices, I recommend checking the Developer Academy course.

Kind regards,
Abhijith
