LEON C/C++ IDE for Eclipse


Software IDE quick-start guide

Cobham Gaisler provides a quick-start guide on how to setup the Eclipse framework to be used for the development of LEON applications, together with a LEON GCC tool-chain. The document shows how to make it possible to cross-compile C/C++ application for the LEON processor family, and to debug them either in a simulator (TSIM) or on a target hardware (GRMON).


System requirements

For additional requirements see the document, tool-chain documentation and Eclipse documentation.

The LIDE plugin - Deprecated

Cobham Gaisler provides an old deprecated plugin for the Eclipse Kepler framework, which allows the C Development Tooling (CDT) to be used for the development of LEON applications. The plugin makes it possible to cross-compile C and C++ application for LEON , and to debug them either in a simulator (TSIM) or on a target hardware (GRMON). The plugin is provided as is and is provided free of charge. No technical support will be provided.
