[Discuss-gnuradio] USRP2 Ethernet link Issues

[Praveen Vikram]

Hi Everyone,

I am currently trying to play around with the USRP2, but am not even able to connect to it.

I have the latest UHD and GNURadio installed from git running on Ubuntu 10.04.

I'am connecting the USRP directly to the Gigabit Interface on my computer. 

I used the Firmware/FPGA image from http://www.ettus.com/downloads/uhd_images/UHD-images-most-recent/

When I switch on the USRP2, all the LED's light up and then LED D & F stay on. But,

-> None of the lights on the ethernet port light up.

-> uhd_find_devices says:

linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.20110315195256.3a1ad3f

No UHD Devices Found

-> find_usrps says

No USRP2 found.

-> ethtool eth0 says

-> lspci | grep Ethernet says

03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12)

0a:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express (rev 21)

I have two gigabit interfaces, i have tried to connect on both with the same result.

-> When I use wireshark to see if any packets are actually sent, I dont see anything going between the USRP2 and my computer.

I have set a static ip (192.168.10.1/255.555.255.0) too.

I have tried different ethernet cables, made sure no pins are broken in either of the ethernet ports.

I'am not sure what I'am doing wrong. I have ferreted the mailing-lists for similar problems but couldn't find any solution. Any help will be appreciated at this point.

Thanks,

Praveen
