The binaries built with the Colibri Linux board support package BSP or provided by a base support package or pro support package are pretty generic. This is good for the start of the development, but generally not optimal for production systems. Therefore vollmann engineering provides a range of customized images for the Colibri.

The production image is a package that serves as a base for a field-use system. It comes with a generic kernel with all devices enabled, a production U-Boot bootloader and a basic OpenEmbedded-based JFFS2 filesystem flash image for direct startup in a standalone system. The filesystem image includes a generic set of applications and can be extended with additional packages from the vollmann engineering feed using the standard OpenEmbedded ipkg mechanism.

The low power image is a package that is optimized to consume low power. It comes with a Linux kernel that only enables devices that are actually used and incorporates patches to allow correct sleep and frequency change functionality. The package includes an adapted U-Boot bootloader that allows correct wake-up after sleep. The package also includes an OpenEmbedded-based JFFS2 filesystem flash image that includes power management daemons.

The quickstart image is a package that is optimized to short startup times. It comes with an optimized U-Boot bootloader for fast startup, a Linux kernel that only includes devices that are actually used for booting and a customized JFFS2 filesystem flash image with modules for devices not compiled into the kernel and optimized startup procedure to arrive at a pre-defined state as soon as possible after power-on.

The real-time image is a package that provides standard real-time functionality. It comes with a Linux 2.6 kernel with several patches applied to provide good real-time functionality. Apart from the real-time specific patches, the kernel is a generic kernel with all devices enabled. The package comes with a production U-Boot bootloader and a basic OpenEmbedded-based JFFS2 filesystem flash image for direct startup in a standalone system. The filesystem image includes a generic set of applications and can be extended with additional packages from the vollmann engineering feed using the standard OpenEmbedded ipkg mechanism.

The hard real-time image is a package that provides hard real-time functionality. It comes with a Linux 2.6 kernel with Xenomai/RTAI patches applied to provide hard real-time functionality. Apart from the real-time specific patches, the kernel is a generic kernel with all devices enabled. No Xenomai/RTAI drivers are included. The package comes with a production U-Boot bootloader and a basic OpenEmbedded-based JFFS2 filesystem flash image for direct startup in a standalone system. The filesystem image includes a generic set of applications and can be extended with additional packages from the vollmann engineering feed using the standard OpenEmbedded ipkg mechanism.

Sometimes none of the above images fits the requirements, and a fully customized image is necessary. Such a package contain exactly those components that were fixed after a detailed review of the requirements.
