[srsran-users] Issues with Running srsENB on USRP E310

[Alin Stoica]

Hello everyone!

I am encountering a persistent issue while attempting to run srsenb with a
USRP E310 device. The process starts normally, but I consistently face a
timeout error during control operations and issues with the End of Burst
(EOB) signal. The specific error message is: [ERROR] [UHD RF] RfnocError:
OpTimeout: Control operation timed out waiting for ACK followed by [INFO]
[UHD RF] Tx while waiting for EOB, timed out... 6.46538 >= 0. Starting new
burst....

Setup Details:
Operating System: Ubuntu 22.04(WSL)
Hardware: USRP E310
srsRAN Version: Version 23.4.0
UHD (USRP Hardware Driver) Version: 4.5.0.0-0-g471af98f
MPM Version: 5.3
FPGA Version: 6.1
FPGA git hash: a2a04e3.clean
Time sources: internal, external, gpsdo
Clock sources: internal
Sensors: ref_locked, gps_locked, temp_fpga, temp_mb, gps_gpgga, gps_sky,
gps_time, gps_tpv
RF Front-end:
RX Frontend: 0
Name: E3xx
Antennas: RX2, TX/RX
Freq range: 70.000 to 6000.000 MHz
Gain range PGA: 0.0 to 76.0 step 1.0 dB
Bandwidth range: 20000000.0 to 40000000.0 step 0.0 Hz
Connection Type: IQ
Uses LO offset: No

I have tried various configurations and parameters, including adjusting the
master clock rate, but the issue persists. I am seeking advice on optimal
settings for the USRP E310 in the context of srsENB, particularly regarding
the handling of control operations and EOB signals. Any insights into the
compatibility between srsRAN and UHD versions or specific performance
settings for the USRP E310 would be highly appreciated.
