Hello,
Finally got DPDK running on my ubuntu 20.04 machine. I have two x310's over a
10Gbe each going to their own port on a intel x520. If I have just a single
x310 hooked up, the rx_samples_to_file and tx_samples_from_file both work
flawlessly at 200 Msps. If they are both hooked up, I get a few errors when
transmitting that I am not able to discern are going to cause me trouble or
not. This is a typical output upon calling tx_from_samples. The [ERROR] [UHD]
and [ERROR] [USRP2] don't seem to be a major issue, since the PC is finding the
x310 without a problem, but I don't know what the [ERROR] [CTRLEP] at the end
is trying to tell me. Any thoughts?
