Issue Description

Built here and also tried apt-get

when I run srsenb ( :$ sudo srsenb ) I get the following output:
`pat@worker:$ sudo srsenb

I get the same with both prebuilt and built here versions. If I leave it running it takes a while but it will dump. Happens with both stock config file and altered. Backtrace --- command='srsenb' version=20.04.2 signal=11 date='24/09/2020 17:14:44' ---

RF configuration

dl_earfcn: EARFCN code for DL (only valid if a single cell is configured in rr.conf)

tx_gain: Transmit gain (dB).

rx_gain: Optional receive gain (dB). If disabled, AGC if enabled

Optional parameters:

dl_freq: Override DL frequency corresponding to dl_earfcn

ul_freq: Override UL frequency corresponding to dl_earfcn (must be set if dl_freq is set)

device_name: Device driver family. Supported options: "auto" (uses first found), "UHD" or "bladeRF"

device_args: Arguments for the device driver. Options are "auto" or any string.

Default for UHD: "recv_frame_size=9232,send_frame_size=9232"

Default for bladeRF: ""

time_adv_nsamples: Transmission time advance (in number of samples) to compensate for RF delay

from antenna to timestamp insertion.

Default "auto". B210 USRP: 100 samples, bladeRF: 27.

For best performance in 2x2 MIMO and >= 15 MHz use the following device_args settings:

USRP B210: num_recv_frames=64,num_send_frames=64

For best performance when BW<5 MHz (25 PRB), use the following device_args settings:

USRP B210: send_frame_size=512,recv_frame_size=512

Log configuration

Log levels can be set for individual layers. "all_level" sets log

level for all layers unless otherwise configured.

Format: e.g. phy_level = info

In the same way, packet hex dumps can be limited for each level.

"all_hex_limit" sets the hex limit for all layers unless otherwise

configured.

Format: e.g. phy_hex_limit = 32

Logging layers: rf, phy, phy_lib, mac, rlc, pdcp, rrc, gtpu, s1ap, stack, all

Logging levels: debug, info, warning, error, none

filename: File path to use for log output. Can be set to stdout

to print logs to standard output

file_max_size: Maximum file size (in kilobytes). When passed, multiple files are created.

If set to negative, a single log file will be created.

[andrepuschmann]

This is a duplicate of #504 I believe. Ball on this is with Nuand. Closing therefore.

[pat-ford]

The error is coming from a different area of code than #504, this is a tx timeout not rx.
