Hi Marcus,
Sorry for the delay.
The sample rate is 15.36Msps.
This is a system similar to 5g NR. It is a full duplex communication
system. It transmits signal in burst mode; Reception has been ongoing.
This program can run stably for several hours to more than 30 hours.
Then I encountered the error mentioned in the last email.
Best regards,
Damon
Given that a single 15.36Msps channel can be supported with a simple
1GiGe link, have you tried a simple 1GiGe link?
Have you tried switching cables and/or SFP+ adaptors?

Hi dear Engineers of Ettus Research,
Our application written based on UHD and USRP X310 cannot run for a
long time(The longest time did not exceed 48 hours).
The x310 is connected to the computer through a 10GbE network card
(X520).
We have tried to use versions 3.15 and 4.1.0.5. UHD throws different
errors:
1. UHD 4.1.0.5
X300 fw communication failure #1
EnvironmentError: IO Error:x300 fw peek32 -reply timed out
Terminate called after throwing an instance of 'uhd::assertion_error'

2. UHD 3.15

at/home/xxx/uhd_3.15.0/uhd/host/lib/rfnoc/ctrl_iface.cpp:151
Is there a solution?
Best regards,
Jason

We're going to need a lot more information about your application.
What sample rates? Is it TX/RX or TX-only? RX-only?
Can you run one of the examples for extended periods, like
rx_samples_to_file, and then have it write to "/dev/null"??
What OS are you on?
