Hi

What version of nRFConnect and the programmer app are you using? Please check that these are up to date.

Are you able to use the DK with the SES or Keil IDEs? If not, it might be that you have deleted the Interface MCU firmware on the JLink somehow. It can be downloaded from here and dropped into the JLink driver folder on your computer.

Best regards,

Simon
