Build OpenOLT

Supported BAL API versions

Currently, OpenOLT supports Broadcom's BAL API, version 3.4.9.6.

Proprietary software requirements

The following proprietary source code is required to build the OpenOLT agent.

  • SW-BCM686OLT_<BAL_VER>.tgz - Broadcom BAL source and Maple SDK
  • sdk-all-<SDK_VER>.tar.gz - Broadcom Qumran SDK
  • ACCTON_BAL_<BAL_VER>-<ACCTON_VER>.patch - Accton/Edgecore's patch

The versions currently supported by the OpenOLT agent are:

  • SW-BCM686OLT_3_4_9_6.tgz
  • sdk-all-6.5.13.tar.gz
  • ACCTON_BAL_3.4.9.6-V202008310101.patch. This is downloadable from the common CSP CS00003233745.

NOTE: the repository does not contain the above three source packages. These are needed to build the OpenOLT agent executable. Contact Dave Baron at Broadcom to access the source packages.

System Requirements

Hardware :

CPU: Dual-core (4 Threads) up.

Memory: 6GB

Storage: 50GB of free space.

Software :

  1. OpenOLT agent builds on Debian GNU/Linux 8.11.1 (jessie) . The ISO installer image is downloadble from here

  2. At least 4G of ram and 4G of swap - compilation is memory intensive

  3. Essential tools for building packages

Install the following packages

apt-get install -y git pkg-config build-essential autoconf libgflags-dev clang libc++-dev unzip libssl-dev gawk debhelper debhelper dh-systemd init-system-helpers curl cmake ccache g++-4.9 wget ca-certificates lcov libgoogle-glog-dev libpcap-dev

Follow the instructions here to install docker-ce. It is not necessary to install docker-ce-cli and containerd.io.

  1. Install cmake version 3.5.1 or above.
cd /tmp
git clone -b v3.5.1 https://gitlab.kitware.com/cmake/cmake.git
cd /tmp/cmake
./bootstrap
make
make install
  1. Install gRPC version v1.31.1
cd /tmp
git clone -b v1.31.1  https://github.com/grpc/grpc
cd /tmp/grpc
git submodule update --init
mkdir -p cmake/build
cd cmake/build
cmake ../.. -DgRPC_INSTALL=ON                \
            -DCMAKE_BUILD_TYPE=Release       \
            -DgRPC_ABSL_PROVIDER=module     \
            -DgRPC_CARES_PROVIDER=module    \
            -DgRPC_PROTOBUF_PROVIDER=module \
            -DgRPC_RE2_PROVIDER=module      \
            -DgRPC_SSL_PROVIDER=module      \
            -DgRPC_ZLIB_PROVIDER=module
make
make install
# copy library and grpc_cpp_plugin to path below.
cp `find . -name "*.a"` /usr/local/lib/
cp `find . -name grpc_cpp_plugin` /usr/local/bin/
  1. Install PcapPlusPlus library
git clone -b v20.08 https://github.com/seladb/PcapPlusPlus.git
./configure-linux.sh —default
make all
make install
  1. Install latest version of Git (optional)

By default the apt-get install an older version of git (2.1.4) on debian jessie 8.11.1. This older version does not support some of the latest git options. You may want to install a later version of git using procedure below.

apt-get remove --purge git ## Removes older verion of git
apt update
apt install make libssl-dev libghc-zlib-dev libcurl4-gnutls-dev libexpat1-dev gettext unzip
wget https://github.com/git/git/archive/v2.18.0.zip -O git.zip
unzip git.zip
cd git-*
make prefix=/usr/local all
sudo make prefix=/usr/local install

Note1: The build environment has been validated with only Jessie 8.11.1 64bit AMD64 OS only. Note2: Make sure you are using g++-4.9 as the default g++ compiler version on your build system. The grpc libraries and openolt agent code has to be compiled with this g++ version.

Build procedure

Clone the openolt repository either from OpenCORD Gerrit:

git clone https://gerrit.opencord.org/openolt

Copy the Broadcom source and patch files to the openolt/agent/download directory:

cd <dir containing Broadcom source and patch files>
cp ACCTON_BAL_3.4.9.6-V202008310101.patch SW-BCM686OLT_3_4_9_6.tgz sdk-all-6.5.13.tar.gz <cloned openolt repo path>/agent/download

Run the configure script to generate the appropriate Makefile scaffolding for the desired target:

cd openolt/agent
./configure

Run make. This can take a while to complete the first time, since it builds ONL and the Broadcom SDKs. Following runs will be much faster, as they only build the OpenOLT agent source.

make OPENOLTDEVICE=asfvolt16

Note that the required ONL version 4.14 is built as part of the above build procedure and is available at path build/onl/OpenNetworkLinux/RELEASE/jessie/amd64/ONL-onl-4.14_ONL-OS8_2020-01-30.0413-72b95a7_AMD64_INSTALLED_INSTALLER. This ONL Installer should be used to flash the OS on the OLT.

If you need to use a specific version of voltha-protos, then specify the git tag/branch corresponding to that specific version:

make OPENOLTDEVICE=asfvolt16 OPENOLT_PROTO_VER=master

By default, the OPENOLT_PROTO_VER defaults to git tag v4.0.3 of the voltha-protos repo.

Optionally, for the NNI port default setting, the options could make the default setting of the NNI port speed.

  • 100G port change to 40Gbps speed
make OPENOLTDEVICE=asfvolt16 PORT_100G_SPEED=40000
  • 100G port change to 10Gbps speed (use Break-out cable)
make OPENOLTDEVICE=asfvolt16 PORT_100G_SPEED=10000
  • 25G port change to 20Gbps speed (Accton/Edgecore ASGvOLT64)
make OPENOLTDEVICE=asgvolt64 PORT_100G_SPEED=100000 PORT_25G_SPEED=20000
  • 25G port change to 10Gbps speed (Accton/Edgecore ASGvOLT64)
make OPENOLTDEVICE=asgvolt64 PORT_100G_SPEED=100000 PORT_25G_SPEED=10000
  • 25G port change to 1Gbps speed (Accton/Edgecore ASGvOLT64)
make OPENOLTDEVICE=asgvolt64 PORT_100G_SPEED=100000 PORT_25G_SPEED=1000

If the build process succeeds, libraries and executables will be created in the openolt/agent/build directory.

Optionally, build the debian package that will be installed on the OLT.

make OPENOLTDEVICE=asfvolt16 deb

If the build process succeeds, a .deb package will be created as well in the openolt/agent/build directory.

Run make with inband option as specified below to build all-in-one ONL image packed with Openolt debian package and Inband OLT startup scripts(Scripts to enable Inband channel and start dev_mgmt_daemon and openolt services). This can take a while to complete the first time, since it builds ONL and the Broadcom SDKs. Following runs will be much faster, as they try to build OpenOLT agent source and Inband ONL with modified Openolt deb package.

make OPENOLTDEVICE=asfvolt16 INBAND=y VLAN_ID=<INBAND_VLAN>
e.g:
make OPENOLTDEVICE=asfvolt16 INBAND=y VLAN_ID=5

If no VLAN_ID is specified in above command it defaults to 4093.

Note that the required INBAND ONL version 4.14 is built as part of the above build procedure and is available at path build/onl/OpenNetworkLinux/RELEASE/jessie/amd64/ONL-onl-4.14_ONL-OS8_2020-04-22. 2206-b4af32e_AMD64_INSTALLED_INSTALLER\. This ONL Installer should be used to flash the OS on the OLT.

NOTE: To compile for ASGvOLT 64 port GPON OLT, set OPENOLTDEVICE to asgvolt64 during build procedure like below.

make OPENOLTDEVICE=asgvolt64

Cleanup

To cleanup the repository and start the build procedure again, run:

# cleans up the agent objects, protos compiled artificats and openolt deb packages
make OPENOLTDEVICE=asfvolt16 clean

# cleans up the agent objects, protos compiled artificats, openolt deb packages and bal sources
make OPENOLTDEVICE=asfvolt16 distclean
