Problem with nRF51 DK on-board J-Link OB USB detection
Hi guys,
Recently purchased nrf51 DK board. I'm facing issue with on board J-Link OB USB detection. The J-Link trace led LD5 on board is off all the time. Tested on different PC's running Win 8 and Fedora 21.
JLinkExe log running on Fedora 21:
|dvb|sudo ./JLinkExe [sudo] password for bhuvan: SEGGER J-Link Commander V4.98b ('?' for help) Compiled Apr 10 2015 20:27:38 Can not connect to J-Link via USB. J-Link>r Reset delay: 0 ms Reset type UNKNOWN: ??? J-Link>
lsusb doesn't show the device! even on device manager on windows doesn't show the device!
Did some one faced this issue! how can i solve this issue ?
