Hello again, There seemed to have wrong rights on file, because after changing rights and editing the file I had this error:

Must both SFP ports of the USRP be plugged, to the host?

I am trying also to reach better stability in OpenAirInterface, and to use USRP through DPDK. I face the exact same error, however I don't have /etc/uhd folder : $ locate uhd.conf /etc/security/limits.d/uhd.conf /etc/security/limits.d/uhd.conf.dpkg-new The content of those files is : @usrp - rtprio 99 I manually created folder ~/.uhd/, and put a uhd.conf file here (I have read somewhere that there are different places where uhd conf file can be located depending on system wide or user wide configuration). No success. Later I also created /etc/uhd folder and copy-pasted the conf file there, still no success. The word separator I used is "-" as you suggested to Florian. Any thought ? Also @Florian, do you see any improvement in OAI stability using DPDK with UHD 3.15? Thank you. Regards, Rodolphe ________________________________ Hi Aaron, thanks for spotting this! Indeed that was a mistake. I also had to adjust the dpdk-num-mbufs=4059 and dpdk-mbuf-cache-size=315 like in the example configuration file for uhd 3.15.0 and then it worked! Yay! Now lets see if OpenAirInterface runs more stable with this! :) Florian.
