As a side note: I tried running the program as "sudo su" with the same exact result.

Is it problematic that the NIC is on the last PCIe slot of the motherboard (same NUMA socket)? I attached the command I'm giving and the output.

Looking over those screenshots again, you'll need to change your dpdk driver path in uhd.conf. Here's what the uncommented parts of uhd.conf should look like for 17.11: [use_dpdk=1] dpdk-mtu=9000 dpdk-driver=/usr/lib/x86_64-linux-gnu/dpdk-17.11-drivers/ dpdk-corelist=1,2,3 dpdk-num-mbufs=4095 dpdk-mbufs-cache-size=315 [dpdk-mac=aa:bb:cc:dd:ee:f1] dpdk-io-cpu = 2 dpdk-ipv4 = 192.168.10.1/24<http://192.168.10.1/24> [dpdk-mac=aa:bb:cc:dd:ee:f2] dpdk-io-cpu = 3 dpdk-ipv4 = 192.168.20.1/24<http://192.168.20.1/24> Note that the IP and MAC need to be changed for your machine.

I'm using the recently released UHD 3.15 LTS. I'm trying to follow the guide to connect via dpdk. Everything in the guide on the Ettus website works however when launching uhd_usrp_probe (as sudo uhd_usrp_probe --args "address = 192.168.30.2, use_dpdk=1") I get the output reported in the output.png attachment. My actual dpdk-devbind.py --status is reported in status.png attachment as well as the uhd.conf I'm using. What am I doing wrong? In the configuration file I tried altering the cores to see if that was an issue but nothing changed.
