Introduction
This manual describes the up-gradation of Yocto tools, the default build system used in RDK Video, from morty(2.2) to dunfell(3.1). In addition to upgrades to opensource packages, Yocto 3.1 also contain Long term Support release feature. The current version lacks the variety of features available in the dunfell.

In order to provide a smooth transition without disturbing the existing branch, we have created a branch called `yocto-dunfell-upgrade` for non-OE layers and another branch called `rdk`RDK/yocto-dunfell-upgrade` for OE layers.
...
Some of the build errors and its root cause is described in the below table. We will keep updating the table as we encounter more errors.

Currently, all the changes are being pushed in these branches. Once it is merged, you will be able to follow the build instructions without any error.
