Renode simulation of RTEMS on LEON3 platform

Copyright (c) 2021 Antmicro

This repository contains a script and test suite to simulate RTEMS on SPARC based LEON3 platform in Renode.

Building

To test it locally, obtain Renode.

On Linux, the easiest way to do it is via the renode-run Python package:

pip3 install --upgrade --user git+https://github.com/antmicro/renode-run
renode-run download

Alternatively you can download a latest nightly Renode package, provided for all major OSes.

You can also build the latest Renode version from GitHub repository. For build instructions, please refer to documentation.

Usage

To start the simulation, run Renode and type:

(monitor) s @leon3_rtems.resc

This will run a RTEMS shell sample bundled with RCC compiler on LEON3 in Renode.

To run sample test cases, run the following in your console:

renode-run test -- leon3_rtems.robot

or fork this project and observe results in GitHub Actions CI workflow.

Running the simulation

You should see the following output on UART:
