nrf51822 evaluation kit not working

[balaji]

Hi, My evaluation board is not detected in nrfgo studio. I can flash the application (simple blink) using keil, but that is not at all working. How can i resolve this problem?

This sounds an awful lot like the exact same problem as you had here. Can you please check, and make sure that you don't have any J-Link devices with such exclamation marks?

Actually Morten, i have two development kit's, one is working fine with my system, but another one is giving trouble as i posted above. And i also updated the driver's for j-link devices, as you said. Now there is not even a single exclamation mark in the device manager.
