The SPEAr Linux Support Package (LSP2.3)

3.1

Overview

The SPEAr Linux Support Package (LSP2.3) provides all the host-side (PC) and target-side

(evaluation board) software components enabling system designers to develop their own

applications for SPEAr-based platforms, as well as to customize the various aspects of the

embedded software architecture.

The components can be summarized as follows:

●

Command-line cross-development toolchain (compiler, linker, building tools, etc.),

running on a Linux x86 PC

●

Graphical IDE (ST Workbench), running on a Linux x86 PC

●

Software for incremental online update of SPEAr Linux Support Package (LSP2.3)

components

●

A set of open source user-space ARM packages (programs and runtime libraries) to be

promptly reused in root filesystems as support to specific applications

●

Linux kernel (2.6.27 or higher), configurable for the different SPEAr evaluation boards;

it includes BSP/device drivers for the SPEAr hardware features

●

U-Boot boot loader, with added support for SPEAr evaluation boards

●

XLoader firmware, configurable for the different SPEAr evaluation boards

Most distribution components are also available as source code (SRPM files).

Full details about STLinux components are reported in other specific documents.
