I'm experiencing an initialization issue with my Ettus X310 USRP device. My setup consists of an Ettus X310 connected through a PCIe Card using a Molex cable to my Linux machine.
I'm running Ubuntu with kernel version 6.8.0-51-generic and have installed all the necessary UHD packages on the system. The X310 is properly detected when running uhd_find_devices, but attempting to probe the device with uhd_usrp_probe results in a RIO session initialization error. I attached the error output below. What is causing this RIO session initialization failure and how can it be resolved? gnb@xgoss-host:~/srsRAN_Project/build4ac5300/apps/gnb$ uhd_find_devices [INFO] [UHD] linux; GNU C++ version 11.4.0; Boost_107400; UHD_4.7.0.0-0ubuntu1~jammy1 -------------------------------------------------- -- UHD Device 0 -------------------------------------------------- Device Address: serial: fpga: HG name: product: X310 resource: RIO0 type: x300 gnb@xgoss-host:~/srsRAN_Project/build4ac5300/apps/gnb$ uhd_usrp_probe [INFO] [UHD] linux; GNU C++ version 11.4.0; Boost_107400; UHD_4.7.0.0-0ubuntu1~jammy1 [INFO] [X300] X300 initialization sequence...
