Has anyone successfully used DPDK with Ubuntu 20.04, UHD 4.0, Intel XL710
NIC, and N310 (or X310)?

I'm running as root. Here is the full command I'm using with my N310 and
the first part of the resulting output. Note that the ERROR is now a UHD
generated error message rather than an error message from the DPDK libs.
One thing I'm looking into is the "vfio-pci" module. The instructions say

Unfortunately that’s one I can’t help with. I don’t have any DPDK capable
machines at my disposal.
I vaguely recall that you have to be root for DPDK to work. Perhaps that’s the
issue?

I'm not convinced anything went wrong in the build of DPDK. The build
didn't indicate any problems. But I wouldn't be surprised to find out that
things aren't being installed where they are expected.
In any case, I realized a mistake in my original post which accounts for
the discrepancy in the

Hi Jorge,
The '[WARNING] [DPDK] Detected use_dpdk argument, but DPDK support not
built in' message means that the version of UHD you are using (in this
case, the 3.15.LTS version you installed via PyBOMBS) was not compiled

Hi Gokul - Did you update UHD to the same version on both the host computer
running OAI as well as the USRP (via the filesystem on the SDcard)? It

I am having trouble with the RFNoC FFT. When using an FFT length of 256 or less
everything works smoothly but when I use a 512 or 1024 length FFT I begin to
receive a flood of repeating packet errors like: ERROR_CODE_BAD_PACKET (Code:
0xf). I haven't been able to find any information
Dear USRP Community,
I am working on OAI project, and trying to run enb using USRP n310. My uhd

command in a different workstation:
*git clone git://github.com/EttusResearch/uhd.git
