UHD USRP装置容量不足

Question

我在CentOS 6.5 64位机器上使用Redhawk 1.10.0，USRP b100带有UHD驱动程序3.7.2。系统能够正确识别USRP b100。它是一个USB设备。我为REDHAWK下载了最新版本的UHD_USRP设备3.0版，并创建了一个包括GPP和UHD_USRP-设备的节点。节点启动时没有任何问题，但当我运行一个简单的波形以RX_DIGITIZER的形式从USRP读取数据时，我得到了以下错误：

Failed to create application: usrp_test_248_173059195 Failed to satisfy 'usesdevice'

我的错在哪里？提前感谢您的帮助。

frontend_tuner_status结构序列定义设备功能和容量。如果序列为空，则分配总是会导致容量不足。空的frontend_tuner_status属性通常是由于未指定目标设备或找不到指定的目标设备。

必须使用target_device结构属性指定目标设备。这可以在Node中完成，也可以在运行时完成。以前版本的USRP_UHD REDHAWK设备只允许使用属性指定IP地址，但为了支持USB连接（通常是非网络连接）的USRP设备，已将其替换为target_Devicestruct属性。

target_device属性允许用户指定ip_address、name和serial或type，并将使用符合条件的第一个USRP硬件设备（如果找到）。应在target_device结构中指定的信息可以通过将update_available_devices属性设置为true来确定，从而用所有找到的设备（与命令行工具uhd_find_devices报告的设备和信息相同）填充available_avices结构序列。

要确定USRP_UHD REDHAWK设备是否连接到目标设备，请检查属性。具体而言，如果未链接到硬件设备，frontend_tuner_status序列以及device_motherboard和device_channels属性将为空。
