This page describes O-DU High/Low pairwise testing procedure in Timer mode.
Only the Integration PTL should edit the delivery status table to track the release validation progress |

Cloning O-DU High code
mkdir odu_high cd odu_high git clone "https://gerrit.o-ran-sc.org/r/o-du/l2" |
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" |
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/ |
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. |
Compilation
cd odu_high/l2/build/odu make odu PHY=INTEL_L1 PHY_MODE=TIMER MACHINE=BIT64 MODE=FDD |
The makefile of odu assumes the required libraries is located at /opt/intel |
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 |
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 |
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 |
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” |
Execution - Running CU Stub
cd odu_high/bin/cu_stub ./cu_stub |
Execution - Running RIC Stub
cd odu_high/bin/ric_stub ./ric_stub |
Execution - Running O-DU High
cd odu_high/bin/odu export LD_LIBRARY_PATH=odu_low/phy/wls_lib/lib:$LD_LIBRARY_PATH ./odu |
