Hi,
I have received two new USRP2 (rev 4) with a BasicRx DB. I connect the
DB,
set the gbit lan so that :

eth1 Link encap:Ethernet HWaddr 00:15:17:e6:86:56
inet addr:192.168.10.1 Bcast:192.168.10.255
Mask:255.255.255.0
inet6 addr: fe80::215:17ff:fee6:8656/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:190 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:27244 (27.2 KB)
Memory:f3000000-f3020000

I connect the USRP2 to the GBIT lan port and try:
ping 192.168.10.2

PING 192.168.10.2 (192.168.10.2) 56(84) bytes of data.
From 192.168.10.1 icmp_seq=2 Destination Host Unreachable
From 192.168.10.1 icmp_seq=3 Destination Host Unreachable
From 192.168.10.1 icmp_seq=4 Destination Host Unreachable

am I missing something ?

(I have also builded UHD and tried uhd_find_devices…result: No UHD
Devices
Found )

Any suggestions ?? (same behaviours on both uspr2)
thanks in advance Luca

Are the UHD images burned onto the sd card?

Are lights E and F light up on the front panel once powered up?

Hi,

I’ve got exactly the same problem.
In my case the lights D and F are light up.

The usrp2_card_burner_gui.py works correctly. I’ve checked that by
flashing the cards with the common firmware.
And that works fine.

Hello,

“destination host unreachable” indicates that the route is not set
correctly. Try

route add -net 192.168.10.0/24 dev eth1

or check

route -n

to see if the routing is using the proper network devices.

Hello,

thanks for your quick answer.

I checked it and I think ists okay.

inupc33:/home/gnuradio/gnuradio/uhd/host/utils # route -n
Kernel IP Routentabelle
Ziel Router Genmask Flags

And in contrast to Luca I used the
ping -I eth1 192.168.10.2 -command to be sure that is use the right
network device.
