Lattice Semiconductor has expanded its commitment to open source embedded system design by releasing an implementation of the uClinux operating system targeted for its LatticeMico32 embedded soft core processor.
The new OS support allows developers to rapidly implement control systems in a design flow that builds on Lattice’s open source embedded solutions approach. It also complements the enhanced capabilities of the LatticeMico32 microprocessor core recently announced with the release of Lattice’s ispLEVER version 7.0 SP2. New features include slave side arbitration for higher performance, enhanced peripheral support for improved integration and support of the LatticeMico32 system design tool flow under Linux.
The uClinux OS port to the LatticeMico32 offers a similar file system and the networking capabilities of Linux, but without an MMU. The port is based on Linux2.6 and includes current versions of uClinux ‘userland’ applications, U-Boot, uClib and uClinux-based user commands. Complete documentation is included with the port. Files needed for a demonstration on a LatticeECP2 evaluation board are available with the release, including the project files required to recreate the demo and begin development. Lattice provides development support on uClinux and Lattice FPGAs through its online uClinux technical forum, as well as its normal applications technical support process.
