Fail to use the n310 in the 5G SA deploy

[MKSBarbosa]

Hello, Everyone,

I have been trying to use srsRAN in 5G SA mode with Docker (docker_open5gs), but I'm facing issues deploying it with the N310.

Here is my Dockerfile:

FROM ubuntu:jammy

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update && \
    apt-get -y install cmake make gcc g++ pkg-config libfftw3-dev libmbedtls-dev libsctp-dev libyaml-cpp-dev libgtest-dev \
    libzmq3-dev software-properties-common pkg-config net-tools iputils-ping git

RUN apt-get update && \
    apt install -y libboost-all-dev libusb-1.0-0-dev doxygen python3-docutils python3-mako python3-numpy python3-ruamel.yaml python3-setuptools

RUN  git clone https://github.com/EttusResearch/uhd.git

RUN cd uhd/host && \
    mkdir build && \
    cd build && \
    git checkout v4.1.0.0

RUN cd uhd/host/build && \
    cmake ../ && \
    make -j $(nproc) && \ 
    make install && \
    ldconfig && \
    uhd_images_downloader

    RUN git clone https://github.com/srsran/srsRAN_Project.git && \
    cd srsRAN_Project && git checkout 4ac5300d4927b5199af69e6bc2e55d061fc33652 && \
    mkdir build && cd build && \
    cmake ../ -DENABLE_EXPORT=ON -DENABLE_ZEROMQ=ON && make -j`nproc` && make install && \
    ldconfig

ENV UHD_IMAGES_DIR=/usr/share/uhd/images/

CMD cd /mnt/srsran && /mnt/srsran/srsran_init.sh

and

The entrypoint (srsran_init.sh) executes this command: gnb -c /etc/srsran/gnb.yml -c /etc/srsran/mimo.yml

And here is my configuration file:

gnb.yml

  addr: AMF_IP                                                    # The address or hostname of the AMF.
  bind_addr: SRS_GNB_IP                                           # A local IP that the gNB binds to for traffic from the AMF.

I have tried UHD 4.7.0.0, 4.4.0.0, and 4.1.0.0, however, I keep encountering the following error:

Can anyone help me solve this?

I am using Ubuntu Server 22, and the N310 is directly connected to the server.

[pgawlowicz]

probably you have to move the eth interface (the one connecting to usrp) to the docker container?

[MKSBarbosa]

Hi, thank you for your reply.

I am using the network_mode: host option in the Docker container for the gNB, and the interface is already connected to the USRP N310.
