  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/

  6. Compilation

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

  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 Non BBU threads in application =========================================================================================================== nr5g_gnb_phy2mac_api_proc_stats_thread: [PID: 8659] binding on [CPU 0] [PRIO: 0] [POLICY: 1] wls_rx_handler (non-rt): [PID: 8663] binding on [CPU 0] =========================================================================================================== PHY>welcome to application console

  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
