1. Load the image with the !OpenAirInterface code on the nodes. After imaging the nodes are '''turned off automatically'''. [[CollapsibleStart(omf load -i baseline.ndz -t all)]] [[Include(Documentation/Short/LoadImage)]][[CollapsibleEnd]] 
2. Turn ON the nodes that successfully imaged (give them some time and check their status with '''omf stat''' before proceeding). [[CollapsibleStart(omf tell -a on -t all)]][[Include(Documentation/Short/TellOn)]][[CollapsibleEnd]]
3. On both nodes (node1-1, node1-2), get the code from Eurocom repositories

{{{
apt-get install subversion git
echo -n | openssl s_client -showcerts -connect gitlab.eurecom.fr:443 2>/dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' >> /etc/ssl/certs/ca-certificates.crt
git clone https://gitlab.eurecom.fr/oai/openairinterface5g.git
}}}

4. Install necessary additional software on both nodes

{{{
cd /root/openairinterface5g/
source oaienv
cd cmake_targets
./build_oai -I --install-optional-packages (need to run only once)
}}}

5. Compile the OAI code

{{{
#If updating eNB
./build_oai --eNB -C -w USRP

#If updating UE
./build_oai --UE -C -w USRP
}}}
