Welcome to uClinux/LM32

uCLinux/LM32 is a port of Linux to the Lattice Mico32 soft-core architecture. Please expect more information on the topic at a later date...

Overview

Theobroma Systems, under contract to Lattice Semiconductor, ported uClinux to the Lattice Mico32 soft-core architecture to provide a highly configurable and low-cost processing solution for deeply embedded applications.

Current version

As of 2008-03-03, a patch (approx. 8KB) against the 2008-02-06 source release has been made available. This patch fixes the following issues:

IRQ for system core timer needs to be auto-detected (issue #206)
signals dispatched from IRQ context cause exceptions (issue #205)
toolchains now build with texinfo 4.11 (issue #204)

The last full release is dated 2008-02-06 and contains the latest improvements. Users should upgrade to this version at the earliest opportunity.

Downloads

To get started quickly, we provide a number of download choices:

the binary-only (.tar.gz, 7.5 MB) distribution contains a bitstream, bootloader, Linux kernel and RAMdisk to immediately get you started with Linux on the Mico32,
a set of pre-built and statically-linked toolchains for Linux/x86 (.tar.gz, 164 MB) and toolchains for Cygwin/Win32 (.tar.gz, 140 MB) are available,
the pre-built MSBConfigParser (.jar, 48 kB) for configuring U-Boot/LM32,
the full source code and build system for the toolchains and all standard uClinux-packages are contained in the complete distribution (.tar.gz, 360 MB).

Documentation
