Issues with Running srsENB on USRP E310 #1243

Issue Description

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

Expected Behavior

The expectation is for srsENB to run without encountering timeout errors or issues related to EOB, establishing a stable LTE eNodeB.

Actual Behaviour

During the execution of srsENB, the process fails to maintain stability, encountering a timeout error and issues with EOB. The error [ERROR] [UHD RF] RfnocError: OpTimeout: Control operation timed out waiting for ACK is consistently observed, and there are problems related to the End of Burst (EOB) signal

Steps to reproduce the problem

Run srsENB with the USRP E310 connected and configured with the following arguments: addr=192.168.10.40,master_clock_rate=16e6. Observe the error message and issues related to EOB during the execution.

Hi, I encountered the same issue, have you resolved it?

Unfortunately not, my conclusion is that the e310 cannot be integrated with srsRAN because of the few mega samples.

Thanks for the reply! Yes I tried to test the E310 capacity with benchmark_rate, the max full duplex rx_rate and tx_rate can only reach to approximately 3 Msps …
