usrp N210 牛刀小试
上篇谈到历经折磨，挫折不断的安装路程。想必一路过关斩将的感觉少许有些成就感。在测试usrp n210是否成功安装，那就来执行一些例程验证。
将千兆网卡接上N210，PC机最好有双网卡否这比较难以想像来回拔插网线（难以保证不切换，因为菜鸟的我不能保证一次ok，需要google帮忙，百度协助）为能够使用双网卡请不要将两个网卡均设置为同一网段，我192.168.1.x网段是上外网的，需要查资料。而千兆设置为192.168.10.x网段即可。N210的缺省ip据说为192.168.10.2，不确定是不是我直接给它设置了个ip，ping通了。
$ sudo ./usrp2_recovery.py --ifc=eth0 --new-ip=192.168.10.3
[sudo] password for xxxx:
('Opening raw socket on interface:', 'eth0')
('Loading packet with ip address:', '192.168.10.3')
Sending packet (22 bytes)
Done
$ ping 192.168.10.3
PING 192.168.10.3 (192.168.10.3) 56(84) bytes of data.
64 bytes from 192.168.10.3: icmp_req=1 ttl=32 time=1.59 ms
64 bytes from 192.168.10.3: icmp_req=2 ttl=32 time=1.04 ms
64 bytes from 192.168.10.3: icmp_req=3 ttl=32 time=1.06 ms
^C
--- 192.168.10.3 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2003ms
rtt min/avg/max/mdev = 1.049/1.234/1.592/0.253 ms
接下来看看是否能检测到N210设备呢，执行/usr/local/bin目录下的./uhd_usrp_probe发现fpga fw不匹配
于是给N210升级，进入下面的链接将 uhd_003.004.003-release_Ubuntu-10.04-x86_64.deb下载并解压升级 http://files.ettus.com/binaries/uhd_stable/latest_release/
具体升级参考了http://kb.microembedded.com/usrp2uhdmanual的升级说明
cd/share/uhd/utils
./usrp_n2xx_net_burner.py --addr= --fw=
./usrp_n2xx_net_burner.py --addr= --fpga=
再次运行成功检测N210设备
