Hi, I have 2 systems (each with host PC and N310) for which I'm having similar issues in trying to get DPDK up and running. After going through the UHD Manual DPDK instructions and DPDK app note, I am past the point at which the "dpdk-devbind" seems to work fine, but I get the following error when I run benchmark_rate.
I am running Ubuntu 20.04.LTS and installed DPDK 18.11.11 by downloading/building from source. I built UHD (latest 4.0) from source and it seemed happy finding DPDK and building with DPDK support. It seems like a compatibility issue, but I can't figure it out. Any suggestions?
