Dear usrp community, I am working on OAI code to implement 5G SA using usrp b210. The uhd installation is done with source installation using ninja. UHD version : UHD_3.15.0.0 I get the following crash error, when I run the gnb:
[NR_PHY] Number of bad PUCCH received: 0 [HW] [recv] received 8604 samples out of 23040 [ERROR] [[HW] ERROR_CODE_BAD_PACKET STREAMER[PHY] rx_rf: Asked for 23040 samples, got 8604 from USRP ] [PHY] problem receiving samples The receive packet handler caught a value exception.

See the application notes for your device. Error: LookupError: KeyError: No devices found for -----> Empty Device Address ---------------------------------------- unpluging the usb cable and then it is ok, but the crash happens whenever I run the gnb. But I also tried adding udev rules from https://files.ettus.com/manual/page_transport.html#transport_usb_udev but unfortunately still the same. Please suggest some solution. Thank you in advance!
