  1. Cloning O-DU High code

    mkdir odu_high
    cd odu_high
    git clone "https://gerrit.o-ran-sc.org/r/o-du/l2"
  2. Cloning O-DU Low code

    mkdir odu_low
    cd odu_low
    - git clone "https://gerrit.o-ran-sc.org/r/o-du/phy"
    - Download code from "https://github.com/intel/FlexRAN"
    
    
  3. Install O-DU High pre-requisite libraries by following https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-l2/en/latest/installation-guide.html .
  4. Install O-DU Low by following https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/index.html .
  5. Compilation Preparation

    mkdir odu_high/l2/src/wls_lib
    mkdir odu_high/l2/src/dpdk_lib
    
    cp odu_low/phy/wls_lib/wls_lib.h odu_high/l2/src/wls_lib/
    cp odu_low/dpdk-19.11/x86_64-native-linuxapp-gcc/include/rte_* odu_high/l2/src/dpdk_lib/

    DPDK library

    O-DU low instructs to build DPDK using x86_64-native-linuxapp-icc

    O-DU high uses x86_64-native-linuxapp-gcc, or library will be missing.

  6. Compilation

    cd odu_high/l2/build/odu
    make odu PHY=INTEL_L1 PHY_MODE=TIMER MACHINE=BIT64 MODE=FDD

    Hardcoded Library Location

    The makefile of odu assumes the required libraries is located at /opt/intel
    Modification of the makefile is needed if the libraries are located at different location.
  7. Execution - Bringing up L1 of O-DU Low

    cd odu_low/phy
    source ./setupenv.sh
    cd odu_low/FlexRAN/l1/bin/nr5g/gnb/l1
    ./l1.sh -e

    Dynamic Library Path

    May need to include the paths to the following libraries in the environment variable LD_LIBRARY_PATH

    ./odu_low/FlexRAN/libs/cpa/bin

    ./odu_low/phy/wls_lib

    ./odu_low/phy/fhi_lib/lib/build

  8. Execution - Bringing up FAPI Translator of O-DU Low

    cd odu_low/phy
    source ./setupenv.sh
    cd odu_low/phy/fapi_5g/bin/
    ./oran_5g_fapi –cfg=oran_5g_fapi.cfg
  9. Assign virtual IP addresses as follows:

    ifconfig <interface name>:ODU “192.168.130.81”
    
    ifconfig <interface name>:CU_STUB “192.168.130.82”
    
    ifconfig <interface name>:RIC_STUB “192.168.130.80”
  10. Execution - Running CU Stub

    cd odu_high/bin/cu_stub
    ./cu_stub
  11. Execution - Running RIC Stub

    cd odu_high/bin/ric_stub
    ./ric_stub
  12. Execution - Running O-DU High

    cd odu_high/bin/odu
    export LD_LIBRARY_PATH=odu_low/phy/wls_lib/lib:$LD_LIBRARY_PATH
    ./odu
