STLinux operating system
  • active Active

The STLinux 2.4 distribution and development environment provides all the software required to build Linux-based systems for ST-based platforms with an ARM or ST40 embedded processor.

The kernel can be ported to customer boards or used directly on ST reference platforms.

STLinux is open source, the majority is delivered in both binary and source form, making it easy to extend and enhance its capabilities for your specific platform.

New kernel-space code (such as additional device drivers) can be added. User-space applications, written in ANSI C or C++, can take advantage of the application level APIs provided by Linux.

A powerful set of cross-development tools make development easy. The tools include state-of-the-art system analysis and trace tools.

During development, STLinux supports a convenient network-based paradigm using ST Micro Connect to download the kernel, and also using NFS to mount the root file system.
