Poky contains a set of default target images. You can list them by executing the following commands:

$ cd /opt/yocto/poky
$ ls meta*/recipes*/images/*.bb

A full description of the different images can be found in the Yocto Project Reference Manual, on Chapter 13, Images. Typically, these default images are used as a base and customized for your own project needs. The most frequently used base default images are:

• core-image-minimal: This is the smallest BusyBox, sysvinit, and udev-based console-only image
• core-image-full-cmdline: This is the BusyBox-based console-only image with full hardware support and a more complete Linux system, including Bash
• core-image-lsb: This is a console-only image that is based on Linux Standard Base (LSB) compliance
• core-image-x11: This is the basic X11 Windows-system-based image with a graphical terminal
• core-image-sato: This is the X11 Window-system-based image with a SATO theme and a GNOME mobile desktop environment
• core-image-weston: This is a Wayland protocol and Weston reference compositor-based image

You will also find images with the following suffixes:

• dev: This image is suitable for development work, as it contains headers and libraries
• sdk: This image includes a complete SDK that can be used for development on the target
• initramfs: This is an image that can be used for a RAM-based root filesystem, which can optionally be embedded with the Linux kernel
