Hi Marcus,
Okay, thanks for that information.
What should we try next?
Thanks,

Could you share the "ifconfig" for your host (or whatever the modern
equivalent is with the "ip" toolset).

Hi Marcus,
I am still interested to know how your team tests to verify the FPGA
is sending the data….meanwhile I did two quick experiments based on
your suggestions.
I have no visibility into the details of the R&D teams testing
apparatus, but I have been told that this feature was tested
in the automated test jig they use. That's all I know.
I'm a (very) part-time contractor, and not an Ettus/NI R&D employee.
So I'm singularly unqualified to talk about the
test setup.
1) Same setup using the second interface I setup on the network card
for the remote port @192.168.30.30, “./remote_rx.py --rate=200e6
--freq=1223e6 --gain=20 --dest-addr=192.168.30.30 --dest-port=54321
--adapter=sfp1 --dest-mac-addr=3c:ec:ef:c2:43:47”.
Setup netcat -ul 54321 to listen to this port, and can be verified as
listening (bottom line):
|Proto Recv-Q Send-Q Local Address Foreign Address State udp 0 0
127.0.0.53:53 0.0.0.0:* udp 0 0 0.0.0.0:111 0.0.0.0:* udp 0 0
0.0.0.0:631 0.0.0.0:* udp 0 0 0.0.0.0:5353 0.0.0.0:* udp 0 0
0.0.0.0:50237 0.0.0.0:* udp 0 0 0.0.0.0:54321 0.0.0.0:* |
Still no traffic to 192.168.30.30 (remote streaming dest), only
control data between USRP (192.168.30.2) and host (192.168.30.1) when
sniffing.
2) Set the dest-addr to be the host (192.168.30.2), which I would
think would be equivalent to “normal streaming”. “./remote_rx.py
--rate=200e6 --freq=1223e6 --gain=20 --dest-addr=192.168.30.2
--dest-port=54321 --adapter=sfp1 --dest-mac-addr=3c:ec:ef:c2:43:47”
Setup netcat -ul 54321 to listen to this port, and can be verified as
listening (bottom line):
|Proto Recv-Q Send-Q Local Address Foreign Address State udp 0 0
127.0.0.53:53 0.0.0.0:* udp 0 0 0.0.0.0:111 0.0.0.0:* udp 0 0
0.0.0.0:631 0.0.0.0:* udp 0 0 0.0.0.0:5353 0.0.0.0:* udp 0 0
0.0.0.0:50237 0.0.0.0:* udp 0 0 0.0.0.0:54321 0.0.0.0:* |
I don’t see any high speed IQ data going between 192.168.30.1 (host)
and 192.168.30.2 (USRP), only the normal control trickle.
Thanks,
