bblayers.conf  local.conf  templateconf.cfg

 bblayers.conf : This file lists the metadata layers to be considered for this project.

 local.conf : This file contains the project-specific configuration variables. You can set common configuration variables to different projects with a  site.conf file, but this is not created by default

templateconf.cfg : This file contains the directory that includes the template

configuration files used to create the project. By default it uses the one pointed to by

the  templateconf file in your Poky installation directory, which is  meta-yocto/

conf by default.

f core-image-minimal : This is the smallest BusyBox-, sysvinit-, and udev-based

console-only image

f core-image-full-cmdline : This is the BusyBox-based console-only image with

full hardware support and a more complete Linux system, including bash

f core-image-lsb : This is a console-only image that is based on Linux Standard

Base compliance

f core-image-x11 : This is the basic X11 Windows-system-based image with a

graphical terminal

f core-image-sato : This is the X11 Window-system-based image with a SATO theme

and a GNOME Mobile desktop environment

f core-image-weston : This is a Wayland protocol and Weston reference compositor-

based image

You will also find images with the following suffixes:

f dev : These images are suitable for development work, as they contain headers and

libraries.

f sdk : These images include a complete SDK that can be used for development on

the target.

f initramfs : This is an image that can be used for a RAM-based root filesystem,

which can optionally be embedded with the Linux kernel.
