Open embedded build

Hi could anyone tell me in how many formats can one create binary packages through OpenEmbedded. and what are the steps to create them?

Not sure to fully understand the question, Yocto/OpenEmbedded support rpm, deb, ipk, tar packaging. You can build yocto using one or several package types, defined by PACKAGE_CLASSES variable. Each time you will build image or a specific application, corresponding package(s) are generated in your deploy build directory (e.g. build-rpb/tmp-rpb-glibc/deploy/rpm).
