-# openolt
+# OpenOLT driver
 
-**openolt** is an SDN Agent for white box Optical Line Terminals (OLTs). It exposes a well-documented, north-bound protobuf/gRPC [API](https://github.com/shadansari/openolt-api) for SDN controllers. [VOLTHA](https://github.com/opencord/voltha) support for **openolt** is under development. 
+**OpenOLT driver** runs on white box Optical Line Terminals (OLTs) and provides a gRPC-based management and control interface to the OLT.
 
-**openolt** currently supports Broadcom's Maple/Qumran chipsets.
+The **OpenOLT driver** is used by [VOLTHA](https://github.com/opencord/voltha) through the [OpenOLT adapter](https://github.com/opencord/voltha/tree/master/voltha/adapters/openolt).

-## Software versions
 
-The following vendor proprietary source files are required to build **openolt**. These files can be obtained from Broadcom under NDA. Once an NDA is signed with Broadcom, these files are made available by Broadcom on their Customer Service Portal (CSP) via case CS3233745.
+## Supported BAL API versions
+
+- 2.4.3.6
+
+## Proprietary software requirements
+The following proprietary source code is required to build **OpenOLT driver**.
 
 - SW-BCM68620_<BAL_VER>.zip - 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.
 - OPENOLT_BAL_<BAL_VER>.patch - A patch to Broadcom software to allow compilation with C++ based openolt.
 
-The versions that have been tested are:
+The versions currently supported by **OpenOLT driver** are:
 
 - SW-BCM68620_2_4_3_6.zip
 - sdk-all-6.5.7.tar.gz
 - ACCTON_BAL_2.4.3.6-V201710131639.patch
 - OPENOLT_BAL_2.4.3.6.patch
 
+Note - This repo does not contain the above four source packages. These are needed to build the OpenOLT driver executable. Contact Broadcom for access to these source packages.
+
+## System Requirements
+
+**OpenOLT driver** builds on Ubuntu 14.04.
+
 ## Build
 
-Clone this repo, copy above four source code zip/patch files to the openolt/download directory, and run make:
+- Clone this repo either from the github mirror or from opencord gerrit:
 ```shell
-git clone git@github.com:OpenOLT/openolt.git
-
-mv SW-BCM68620_2_4_3_6.zip sdk-all-6.5.7.tar.gz ACCTON_BAL_2.4.3.6-V201710131639.patch OPENOLT_BAL_2.4.3.6.zip openolt/download
-
+git clone git@github.com:opencord/openolt.git
+or
+git clone https://gerrit.opencord.org/openolt
+```
+- Copy Broadcom sources (and patches) to the openolt/download directory:
+```shell
+cd openolt/download
+cp SW-BCM68620_2_4_3_6.zip sdk-all-6.5.7.tar.gz ACCTON_BAL_2.4.3.6-V201710131639.patch OPENOLT_BAL_2.4.3.6.zip ./download
+```
+- Run "make prereq" to install package dependencies. This is usually a one-time thing  (unless there is change in the dependencies).
+```shell
 make prereq
+```
+- Run "make" or "make all". This can take a while to complete the first time around since it builds ONL and Broadcom SDKs. Subsequent runs are much faster as they only build the **OpenOLT driver** source.
+```shell
 make
 ```
-The **build** directory contains all the build artifacts:
-
-- **release_asfvolt16_V02.04.201710131639.tar.gz** - Broadcom BAL (specifically, this tar ball includes the bal_core_dist)
-- **openolt** - the **openolt** agent/driver
-- **libgrpc++_reflection.so.1  libgrpc++.so.1  libgrpc.so.5** - gRPC libraries
-
-## Copy files to target OLT
-
-1. Untar **release_asfvolt16_V02.04.201710131639.tar.gz** in the root (top level) directory
-2. Copy **openolt** to /broadcom
-3. Copy the gRPC libraries to /usr/local/lib
-
-## Update system library indexes
+- Finally, build the debian package that will be installed on the OLT.
 ```shell
-ldconfig
+make deb
+```
+- If the build succeeds, the **openolt.deb** package is created in the **openolt/build** directory. Copy **openolt.deb** to the OLT
+```shell
+scp openolt/build/openolt.deb root@10.6.0.201:~/.
 ```
 
+## Install
+
+- Install the openolt.deb package on the OLT
+```shell
+dpkg -i openolt.deb
+```
+- Reboot the OLT
+```shell
+reboot
+```
 
 ## Run
 
-- Run bal_core_dist:
+- Run bal_core_dist in one terminal:
 ```shell
 cd /broadcom
 ./bal_core_dist -C 10.6.0.201:40000 -A 10.6.0.201:50000
 ```
-- Run openolt:
+- Run openolt in another terminal:
 ```shell
 cd /broadcom
-export LD_LIBRARY_PATH=/broadcom
 ./openolt  -C 10.6.0.201:40000 -A 10.6.0.201:50000
 ```
-(Note - Substitute 10.6.0.201 with a local IP of the OLT - e.g. mgmt interface IP).
+
+## Connect from VOLTHA
+
+- In VOLTHA cli, preprovision and enable the OLT:
+```shell
+(voltha) preprovision_olt -t openolt -H 10.6.0.201:9191
+(voltha) enable
+```
+
+Note:
+- **OpenOLT driver** uses port 9191 for its gRPC channel
+ - Substitute 10.6.0.201 in above steps with mgmt IP of your OLT
