Re: [Discuss-gnuradio] Problem with FW and FPGA images

Hi Josh, 

The sequence of the LEDs is D and F coming green just in the same way as the video apart from the B led where I cannot see why to come green? 

The ethernet is properly configured. 

The green led on the ethernet also goes on. There is no way that the ethernet jack is faulty or sth like that as the same usrp2 with the same settings is just working fine on another laptop with UHD_003.004.000 - 325- g7e296167 revision. 

I don't really know what's the problem, may be I will try solving it by monitoring the serial output. 

The thing that really attracted my attention is that sometimes there is a connection and after just typing uhd_find_devices the connection is lost.

Any other ideas guys?

Thanks again,

Few things I can think of:

1) Do you see this boot sequence on power up?

2) Do you see the green LED on the ethernet jack go on?

3) The serial port can also help:

4) ethernet configured? just a thought:
