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?
