USRP N200 not being identified by the host running Suse

All,

When I connect my USRP N200 to a PC running Suse, run ifconfig eth0
192.168.10.1 command, and then run command uhd_usrp_probe
–args=“addr=192.168.10.2”, I see the famous error message:

LookupError: KeyError: No devices found for ----->
Empty Device Address

The weird fact is that I have 9 other USRP N200 radios which get
detected when I run the command uhd_usrp_probe
–args=“addr=192.168.10.2” on the same PC (so it shouldn’t be a firewall
issue). For the problematic USRP N200 I have done the following:

ping 192.168.10.1 which is fine
ping 192.168.10.2 which shows the error message that destination is
unreachable

I have also used switch S2 to enter into safe mode, burn the right
binaries (3.4.4 from maint branch), power-cycle the device but the
problem persists.

Any ideas on what might be preventing the USRP N200 from being
identified by the host PC?

Thanks in anticipation,
Mahboob

Does the green “Link” light on the USRP come on, and does the yellow
activity light blink from time to time when
it’s plugged in to the host machine?

Hi Marcus,

I assume you are talking about the green LED on the top left of Ethernet
port on USRP N200. If so, then it remains On. However, I don’t see any
yellow activity light at all. Furthermore, only LED D and F are On.

Thanks,
Mahboob

Hi Marcus,

Thanks for the helpful suggestion. The USRP is indeed using an IP
address of 192.168.10.3. Sure, I will restore the defult address by
running usrp2_recovery.py later.

Thanks,
Mahboob

You might want to try using usrp2_recovery.py you’ll have to run it as
root, and it will attempt to restore to the default address.

I suspect that your device had its IP address changed.
