[Discuss-gnuradio] uhd_find_devices error

[devin kelly]

Hello,

I have a strange problem with uhd_find_devices.  I can do

[dkelly uhd]+master$ uhd_find_devices --args="addr=192.168.10.2"
linux; GNU C++ version 4.4.5; Boost_104000; UHD_20101122.202304.0c147c9

--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
   type: usrp2
   addr: 192.168.10.2
   name: dk-usrp2
   serial: 00:50:c2:85:30:52

fine, as you can see.   But everything else I try fails.  Note I have a USRP1 too here.

[dkelly uhd]+master$ sudo uhd_find_devices --args="type=usrp2"
linux; GNU C++ version 4.4.5; Boost_104000; UHD_20101122.202304.0c147c9

No UHD Devices Found

          [dkelly uhd]+master$ sudo uhd_find_devices --args="type=usrp1"

linux; GNU C++ version 4.4.5; Boost_104000; UHD_20101122.202304.0c147c9

I've noticed when when I use the addr argument that I see in wireshark that exactly 180 packets are communicated between my pc andthe usrp2.  I don't see any packets on either interface for any other argument.

Here is my ifconfig:

eth3    Link encap:Ethernet  HWaddr 00:22:3f:f6:36:40 
          inet6 addr: fe80::222:3fff:fef6:3640/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:17375493 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6397200 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:4261877192 (4.2 GB)  TX bytes:499316331 (499.3 MB)
          Interrupt:16 Base address:0x6700

eth3:0 Link encap:Ethernet  HWaddr 00:22:3f:f6:36:40 
          inet addr:192.168.10.1  Bcast:0.0.0.0  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          Interrupt:16 Base address:0x6700

Does anyone have any ideas for for why only the addr argument works?  I'd like to use my USRP1 with the UHD.

Also, while I'm here, do I have to update anything (like reflashing the eeprom) on my USRP1 for it to work with the UHD?

Thanks for any help,
Devin
