Hi list, I just received 2 USRPN200 this morning. First start: the led boot sequence passes only 1 cycle (instead of 2 normally) and, after only F led remains on. If i reboot (turn on/turn off), still 1 cycle on boot sequence, and after, all the leds are now off (inclluding D and F). The power supply has been checked on another USRPN200 and it works. Internal power supply (2.5,3.3 and 1.2V) has been tested and presents the right voltage on J107, J104 and J105. Any idea on what's going on ? Thanks, Damien

Not sure, but perhaps its not booting into the runtime image. I guess the best suggestion would be to hold the safe boot button down. The link should come up. Then you can re-burn good runtime images in with the net burner tool.

Ssomeone else of the list has already provided me the solution, but forgot to CC the list. And it was the same as yours. But anyway thanks a lot for your help, Damien 2013/8/22 Josh Blum <josh@ettus.com> > > > On 08/22/2013 06:36 AM, Damien Serant wrote: > > Hi list, > > > > I just received 2 USRPN200 this morning.
