wpe-alexa.bbMain recipe for downloading the AVS SDK and its compilation, linking it with RDK skill mapping module.CMF hosted


Code Block
1. Initialize and download the code base
 - Example for RaspberryPi:
 $ repo init -u https://code.rdkcentral.com/r/manifests -m rdkv-nosrc.xml -b thunder-next
 $ repo sync

2. Download the meta-rdk-voice layer in project root
 $ git clone https://code.rdkcentral.com/r/components/generic/rdk-oe/meta-rdk-voice

3. Add to BBLAYERS
 $ vi meta-rdk/conf/bblayers.conf.sample
 BBLAYERS += "${@'${RDKROOT}/meta-rdk-voice' if os.path.isfile('${RDKROOT}/meta-rdk-voice/conf/layer.conf') else ''}"

4. Optionally if wanted to use MIC based implementation (Ignore if using BLE voice remote)
 $ vi meta-rdk-voice/conf/layer.conf
 - enable the below commented line
 #DISTRO_FEATURES_append = " alexa_ffv"

5.Build the image target
 - Example for RaspberryPi
 $ source meta-cmf-raspberrypi/setup-environment
 ### select meta-cmf-raspberrypi/conf/machine/raspberrypi-rdk-hybrid-thunder.conf ###
 $ bitbake rdk-generic-hybrid-thunder-image
