我在 CentOS 6.5 机器 64 位上使用 Redhawk 1.10.0 和带有 UHD 驱动程序 3.7.2 的 USRP b100。USRP b100 被系统正确识别。它是一个 USB 设备。我下载了最新版本的 UHD_USRP Device ver。REDHAWK 3.0 和我创建了一个包含 GPP 和 UHD_USRP 设备的节点。节点启动没有任何问题,但是当我运行一个简单的波形从 USRP 读取数据作为 RX_DIGITIZER 时,我收到以下错误:

我的错在哪里?提前感谢您的帮助。

frontend_tuner_status结构序列定义了设备功能和容量。如果序列为空,分配总是会导致容量不足。空的frontend_tuner_status属性通常是未指定目标设备或无法找到指定目标设备的结果。

您必须使用target_device结构属性指定目标设备。这可以在节点内或运行时完成。以前版本的 USRP_UHD REDHAWK 设备仅允许使用属性指定 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_device结构属性.

target_device属性允许用户指定ip_addressnameserialtype,并将使用第一个符合条件的 USRP 硬件设备(如果找到)。应该在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,从而导致可用的设备结构序列填充所有找到的设备(相同的设备和命令行工具报告的信息uhd_find_devices)。

要确定 USRP_UHD REDHAWK 设备是否连接到目标设备,请检查属性。具体来说,如果未链接到硬件设备以及device_motherboardsdevice_channels属性,则frontend_tuner_status序列将为空。
