Problem is OVERFLOW that means some samples missing.

Could you show me N310 connection mode?

I suggest to use 10GB network cable to connect to computer.

谢谢，有任何问题请随时与我联系！

主题: [USRP-users] OAI with USRP N310

Dear community,

I would like to use OpenAirInterface with the USRP N310 and I am having overflow problems. I am forwarding here the email I sent to the OAI mail list, because I think the problem is with the USRP and non-real time operations.

Does anyone have any ideas?

Thanks in advance,

Giuseppe

Dear community,

After solving problems with OAI installation and USRP N310 configuration, I am trying to create a 5G SA link, starting with gNB.

I tried this:
sudo ./nr-softmodem -O ../../../ci-scripts/conf_files/gnb.band78.tm1.106PRB.usrpn300.conf --sa --args clock_source=internal

But it gives problems that I think are related to the fact that probably the operations are not in real time.

For example:
[PHY] rx_rf: Asked for 30720 samples, got 18906 from USRP
[PHY] problem receiving samples
LLLLLLLLLLLLLLLLLLLLLLLLLLLO[HW] [recv] received 18906 samples out of 30720
[HW] Time: 1.41826 s
ERROR_CODE_OVERFLOW (Overflow)

Or, even earlier:
[WARNING] [MPM.RPCServer] A timeout event occured!

Also, I would like to attach a log file but I can't find it, and using the "> file_log.txt" at the end of the command it all goes immediately in overflow.

Does anyone have any ideas?
