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,

Components

The following components are :

These components have dependency with the following existing components:

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.

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
