Operators are advised to get into an agreement with RDK Management LLC to obtain the free license so as to use the complete RDK Code base in their platform. More details about license is available at https://rdkcentral.com/licenses/ . Please email info@rdkcentral.com if you have additional questions about licenses or membership
Operator can choose preferable device from OEM and also get details from SoC vendors, SoC vendors will already have RDK ported on top of their SoC so they will be having all the features supported in SoC so based on that Operator's can select a OEM with preferred SoC platform and then they can start integrating features that Operator requires on top of the OEM layer so that they can have final product.
This document will detail the recommended step by step procedure of adopting RDK by a Operator.
The first step to get a fully functional product is to define the product features and see if they meet the standard requirements. See here to know what are all the features available in RDK-V and can implement based on your requirement. SoC can use this as a guide while engineering the RDK SoC platform.
Operators can make use of the details available below to start developing a Yocto build to do the final additions of Operator specific changes to the device. This will help Operator to add their own final product features as well as Operator specific patches/changes.
Yocto based RDK builds are flexible enough to easily accommodate SoC / OEM / Operator / third party changes. The starting point for the Yocto builds are a manifest file. The manifest file is an xml file that contains details of the different open embedded Yocto build layers, meta layers , rdk as well as open source components that needs to be fetched during initial stages ( than during bitbake time ) as well as the URL locations from where the data can be pulled. A set of sample manifests that can be used as a template for developing Operator specific manifests are given below
To match the layered structure of Yocto builds, a Operator specific layer is used to include Operator changes and additions. Use the yocto-layer create sub-command to create a new general layer.
$ yocto-layer create mylayer
There shall be separate device (machine) configuration file (.conf) for each device for the particular chip family for which the layer is intended for. The general naming terminology for Operator layer is meta-rdk-<soc name>
The device (machine) configuration file shall include corresponding include (.inc) file to get machine configuration details.
Each meta-* layer should have a conf folder containing the machine configuration we can select during 'source setup-environment' . Optionally it can also have a class/classes folder for keeping information that is useful to share between metadata files.
To add a machine configuration, you need to add a .conf file with details of the device being added to the conf/machine/ file. In the machine conf file the basic machine configuration should be defined.
Once the conf files are in place, the layer details need to be added to the corresponding package group file. Based on platform, the package group file will be grouped into multiple files with one bitbake fiile and multiple append files. Operator can add the Operator layer details to required package group append files applicable to the target device build to get the features into the final build
Operators will be having a range of Operator specific applications from simple generic device information apps to Operator specific content applications. RDK's Yocto based layered structure allows Operators to easily integrate, upgrade and maintain their apps in their RDK based IP Set-top devices. For more details on App support in RDK, please refer Applications(only for RDK licensee) as well as Operator Platform Firmware for the engineering details.
RDK supports usage of multiple User Interface in the RDK IP Set-top devices. Operators can choose from among the already available UIs that are available with RDK as well as develop and use their own UI. For more information on UI support in RDK, please refer User Interface(only for RDK licensee).
Based on resident app reference implementation Operator need to bring up the UI.
Along with the Operator specific apps, Operator can support a lot of generic apps in RDK IP Set-top devices by taking advantage of RDK Support for Native as well as Web Apps in IP based Set-top platforms. Operator can easily port native apps in their platforms (for some third party apps, Operator need to obtain certification from those third party) or can host their own app store and then use Web Apps to show content. For more information on App support in RDK, please refer Applications (only for RDK licensee).
Operator needs to add provisioning support in device so that Device provisioning can be done once deployed at customer premise. The steps for this varies based on platform as well as Operator type.
Provisioning support refers to the scenario such as when you launch Sample app on your mobile it takes to login page and so you have to login there, account there i.e. actually the app has to authenticate your login.
Disaster recovery is an inevitable part of the CPE life cycle. Operator, based on their disaster recovery strategy, could add support for this in the device. While there are some generic guidelines followed across industry, there is no single step that works for all. Operators could easily add their business logic to RDK as part of Operator firmware engineering as described in Operator Platform Firmware.
As an operator they have to handle crashes/disaster happens and support any factory reset like OTA upgrade.
Once the device engineering is completed from Operator side, the device can be test and verified easily by the Certification support provided by RDKM. Details of coverage as well as major cases are explained here (only for RDK licensee) .
Certification suite is available at RDK IP Set-top Product Certification (only for RDK licensee) and for TDK test app please refer TDK-V Documentation.
In short, to get an RDK based device to field, Operators need to get
