Purpose

Create a portable OS in C for embedded systems, free of tool and vendor lock-in issues.

Background

Open source embedded operating systems have been around for a while. The best of these often get absorbed or overly influenced by organizations; that influence can affect how “open” the OS is, device support and OS features. Device support is the major pain point, as is compiler/tooling.

Requirements

This will evolve; currently:

• Developed in C99.
• Bare metal, avoids compiler and chip vendor libraries.
• Minimal use of macros.
• Easily to port and compile.
