Hello Sam,
We are using the DPDK 19.11, and UHD 3.14.1. The hardware setup is N310(SFP1)<->(ethernet-to-thunderbolt)<->Laptop (with thunderbolt). The problem with the config file is, that we could not find the config file anywhere neither on the root or the user folder. We have created one, and added the DPDK one (from the site). But I seriously believe that it is not seen/used. As the error No CHDR interfaces found! Is related to the no IP DPDK interfaces (presumably). Thank you for your support!

What version of UHD do you have on the host? I'm not sure that mode of failure is something I'd chalk up to the DPDK install. Could you give some detail on your config file, DPDK install version(s), and hardware setup as well?

I have managed to build the DPDK with uhd successfully, however when I run the probe command I receive the following error. EAL: Starting I/O threads!

Error: RuntimeError: Failed to run enumerate_rfnoc_blocks() My guess from reading back posts from the forum, is that the proper DPDK file is not read. I can see a /etc/conf/uhd.conf file, but no /root/.uhd/uhd.conf file. Am I in the right direction, and if so, how do I enable the user conf file? If not, is there a direction I should head towards?
