Get kernel configs from running OS
You can get the .config file in running Linux OS by the following command.
# zcat /proc/config.gz > current.config
Furthermore, this feature is enabled by CONFIG_IKCONFIG_PROC.

In this section, we share some tips to use & modify BB files.
How to get multi-sources from GIT server
You can assign a name to distinguish the different GIT URIs, and define different destsuffix to save them respectively. Furthermore, to override SRCREV with the name, you can assign different commit id for each GIT branch.
SRC_URI = " \
git://git.allseenalliance.org/gerrit/core/alljoyn.git;protocol=https;branch=${GIT_BRANCH};name=router;destsuffix=git/core/alljoyn \
git://git.allseenalliance.org/gerrit/services/base.git;protocol=https;branch=${GIT_BRANCH};name=services;destsuffix=git/services/base \

SRCREV_router = "0d71b216bb3a3cadc615c3eda6f8200093c5e117"
SRCREV_services = "403cda579242701d42d2d7c0da308d63a8f46070"
Skip QA check
You can skip the specific QA check for your packages. For details, check the insane.bbclass bbclass in Yocto Project Reference Manual.
INSANE_SKIP_${PN} += "dev-so"
Create BB file to install pre-built SO binaries
Below is an example to add SO binaries into your image. You may need to modify the blue items for your path & library name.
# Avoid package splitting into run-time and debug components
INHIBIT_PACKAGE_DEBUG_SPLIT = "1"
# Avoid QA Error for already-stripped
INHIBIT_PACKAGE_STRIP = "1"
# List the files for Package
FILES_${PN} += "/usr/lib"
# Put all SO files in main rpm package
FILES_SOLIBSDEV = ""
INSANE_SKIP_${PN} += "dev-so"
# Set alias name to satisfy runtime dependencies
RPROVIDES_${PN} = "libsusi-4.00.so"
