ld5 flashing quickly, board not visible

[Lene]

Hi, I have been working with my nrf51 DK for a while now without problems. When I first connected the board to the computer today, the ld5 led was blinking very quickly, and the board was not visible anymore.

I have tried the tips in this thread: [thread] (devzone.nordicsemi.com/.../), but when I enter the bootloader mode, no new drives shows up on my computer so I cant instal a new. (but the ld5 is blinking correct acording to bootloader mode)

Any tips on how I can get my board visible again?

Info that might be relevant: SDK 10, PCA10028, N51422...AC, s310, windows 10

Thanks for your reply!

The board became visible in bootloader mode after changing to another usb cabel, so the problem is resolved :-)
