BLU is a development environment for mGSTEP and a demo of its technologies. As a project deliverable it hosts a cross-compiler build automation tool that can create BLU or a derivative embedded OS image from a manifest file listing the components to be included. BLU and its purpose built derivatives implement an A/B update mechanism. Once installed to the boot destination (partition) any subsequent updates are applied as an OS image to the alternate destination. As a result there is no package management. The update scheme is supported on both MBR and GPT partitioned disks. Request an evaluation demo of BLU.
mGSTEP implements a subset of Apple's Cocoa frameworks which have evolved from NeXT's OPENSTEP API. Development is focused on embedded devices capable of running a high-level operating system (HLOS) with GUI support for both X11 and the Linux frame-buffer.
The Cocoa Controls website hosts a valuable repository of GUI controls for Apple platforms. Many listed controls will require some porting to use with mGSTEP which implements only a subset of MacOSX Cocoa and no part of iOS's UIKit.
