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"

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 .
Install O-DU Low by following https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/index.html .

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
Modification of the makefile is needed if the libraries are located at different location.

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

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
