Yocto Build Steps

To build, follow below instructions

...

bzip2 -d <path to ImageName.wic.bz2>
sudo -E bmaptool copy --nobmap <path to ImageName.wic> <path to SD card space>

Example:

$ bzip2 -d rdk-generic-broadband-image-raspberrypi4-64-rdk-broadband.wic.bz2
$ sudo -E bmaptool copy --nobmap rdk-generic-broadband-image-raspberrypi4-64-rdk-broadband.wic /dev/sdb

OEM Side Changes Required

Global CFLAGS

NOTE: This can be added in ccsp_common inc files. So, will be available for all ccsp components.

For DBUS Enabling support

            By default, rbus is enabled in rpi4 64b build. For dbus enabling in rpi4 64b build, please follow the below steps,

Delete the below lines from below file's,
 
File path : ~/meta-cmf-raspberrypi/meta-rdk-broadband/recipes-ccsp/util/utopia.bbappend
    touch \/nvram\/rbus_support ' ${D}${sysconfdir}/utopia/utopia_init.sh 

File path : ~/meta-cmf-raspberrypi/recipes-core/dbus/dbus_%.bbappend

{ 
# Removing dbus service in 64bit arch alone
 rm ${D}${systemd_system_unitdir}/dbus.service 
}
