我在用OAI搭建gNB，用USRP N310連在gNB上，用指令uhd_find_devices是可以找到usrp的，uhd_usrp_probe也是可以正常運行的。在運行
oai@oai-System-Product-Name:~/openairinterface5g/cmake_targets/ran_build/build$ sudo ./nr-softmodem -O ~/openairinterface5g/targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.con
時，會一直報錯
[HW] UHD version 3.15.0.HEAD-0-gaea0e2de (3.15.0)
[HW] No USRP Device Found.
Assertion (ret==0) failed!
In ru_thread() /home/oai/openairinterface5g/executables/nr-ru.c:1475
Cannot connect to local radio
Exiting execution
有沒有大佬遇到過類似問題哇，求問怎么解決的呀！
