Note : The above bug fixes changes are temporary given as instructions. This is not required once the change is gets merged into the appropriate repo.

Distro Features

We are using the following distro features to enable rdkb wanmanager . Please add the following distro features into OEM machine configuration file,

  • rdkb_wan_manager : Used to enable RDK WanManager and json hal

Please open the below rpi machine configuration file and add the following line in that file .

 $ vi ~/meta-cmf-raspberrypi/conf/machine/raspberrypi-rdk-broadband.conf

DISTRO_FEATURES_append = "  rdkb_wan_manager"

Also , we need to disable the GwProvapp-EthWan component in ccsp packagegroup . For that, please open the below file and add the following line in that file ,

$ vi ~/meta-cmf-raspberrypi/recipes-core/packagegroups/packagegroup-rdk-ccsp-broadband.bbappend

GWPROVAPP = ""

Note :  The above distro changes are temporary given as instructions. This is not required once the change is gets merged into the appropriate repo.

Build steps

Build Steps
$ MACHINE=raspberrypi-rdk-broadband source meta-cmf-raspberrypi/setup-environment
$ bitbake rdk-generic-broadband-image

We will get the following rdk-wanmanager compilation errors While bitbaking the target image,

rdk-wanmanager Compilation Errors

Components

The following components & meta-layers are used for Porting of  RdkWanManager in RPI Target Platform ,

Manifest Changes

Manifest File
<project name="rdkb/components/opensource/ccsp/RdkWanManager" revision="rdk-next"/>
<project name="rdkb/components/generic/json-rpc" revision="rdk-next"/>

Note :  RdkWanManager Project will be added in RPI Manifest , Once the RdkWanManager Compilation error changes are merged in rdk-next(58500) 

Persistent (PSM) configuration changes

For wanmanager, the default configurations are stored in PSM. As of now, we have 1 interfaces defined for WAN in wanmanager modules (i,e) wanoe.

For WANOE, by default we are using `eth0 `port for WAN connection. 

<Record name=""dmsb.wanmanager.if.2.Name"" type=""astr"">eth0</Record>

CcspEthAgent will start once it gets the signal status from CR but CR is taking long time to send the Signal status .

CR is waiting to get the MTA System_Ready Signal but MTA is not supported for RPI.

PandM DM was not loading after the WanManager Integration

Device.DHCPv6.Client.{i} and Device.DHCPv4.Client.{i}. was
moved to the WanManager . But the DMs was not removed

Removed the Device.DHCPv6.Client.{i} and Device.DHCPv4.
Client.{i}. from the PandM XML file. 		https://code.rdkcentral.com/r/c/rdk/components/generic/rdk-oe/meta-cmf-raspberrypi/+/58681/2/recipes-ccsp/ccsp/ccsp-p-and-m.bbappend
