I am using Ubuntu 18.04, an N310 with the current master builds. I am
currently testing basic operation using a USB/Ethernet adaptor for the
management connection, and a 1 GB Ethernet connection straight from
the computer’s NIC port to the SFP0 port on the N310.
I have built from source and can make it through all of the examples
and benchmarking exercises successfully. I am also able to
successfully run the tx_waveform example with a streaming rate of 25e6
with a master clock rate of 125e6. This seems to be the limit,
31.25e6 causes underruns.
For 16-bit samples on a 1GiGe connection, 25e6 SPS is the limit.
Despite the streaming link seeming to work, there are chronic warnings
such as:
“[WARNING] [MPMD] Could not determine link speed; using 1GibE max
speed of 125000000
The network connections were set up within Ubuntu’s network manager,
with MTUBytes = 8000 (also set in the N310’s /etc/system/network/ files).
Autonegotiation is enabled on both ends, per ethtool outputs.
Any input on where these warnings originate, and if there is a way to
suppress them?
