O-DU High and Low Integration

This page describes O-DU High/Low pairwise testing procedure in Timer mode.

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/phy/dpdk-19.11/x86_64-native-linuxapp-gcc/include 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

   cd odu_low/phy
   source ./setupenv.sh
