= Open Projects =

Welcome! Whether you're here because of [wiki:GSoC  Summer of Code (SOC)] or just want to scratch an itch to hack, we invite you to peruse our projects and ask about them on the [wiki:TBR/Website/RTEMSMailingLists  RTEMS mailing list] or [wiki:Developer/IRC IRC].  If you plan to submit a proposal to do something for the RTEMS Project as part of a SOC, see [wiki:GSoC/GettingStarted  Getting Started for SoC Students]. RTEMS projects span kernel hacking, adding support for a new board (BSP), improving the development environment, developing tests, and more.

If you want to get your feet wet with RTEMS then check out our [wiki:Developer/SmallProjects  small projects page] where you can find projects that require little coding skill and are appropriate for those new to RTEMS or open source software projects. If you are interested in one of these projects but are not able to code and test it yourself, consider sponsoring one of the core RTEMS developers to do it for you. Volunteering or sponsoring is how things get done -- users keep RTEMS development alive!

Most of these projects will take between a few weeks and a few months of effort by a person who is familiar with the general use of GNU/Linux and GNU tools.  Many RTEMS projects are done by student or volunteer coders, so we try to define small projects or subtasks that can be completed and committed individually. Most of the projects are feasible as a [wiki:GSoC  Summer of Code] project.  Since some projects have multiple steps, students should work with prospective mentors to define the scope of work in their proposal.  Similarly, some projects might be a starting point for a class project or graduate thesis.


[[TOC(Developer/OpenProjects, depth=2)]]

= Overview =

The order of projects in the list does not reflect their importance, difficulty, or feasibility. Our project list is not exclusive: if you have an idea, solicit feedback from the project's [wiki:TBR/Website/RTEMSMailingLists mailing list] or [wiki:Developer/IRC IRC channel]; many developers sit in IRC and check it (and their email) infrequently throughout the day, so be patient!  There may or may not be enough work on a project to constitute an SOC project, and some of these are past SOC projects.  If you are interested in one of these, please ask on the mailing list or IRC.

Projects in '''Bold text''' are '''higher priority''' simply meaning that users or developers have expressed a lot of interest in such projects. Projects in ''Italic text'' are space-oriented and therefore suitable for [http://sophia.estec.esa.int/socis/ SOCIS].

If you have a new project add it to the appropriate list below, link to a wiki page below !Projects/Open/ and use the [wiki:PageTemplates/ProjectDescriptionTemplate  Open Project Template]. Briefly (1 sentence) summarize the project.

If one of the projects sounds interesting, but lacks detail, ask on an RTEMS mailing list for details and we can all help scope the project.

= Testing =

Testing a large body of software like RTEMS is in a continual state of improvement.  There is always a need for more test cases and easier ways to run them all and decode the results.  In addition, we want to be  able to run all tests on as many hardware and simulator configurations as possible.  Testing doesn't sound exciting to most people but when you combine the breadth of what we need to test with our desire for 100% instruction and branch path coverage, you get some very interesting and challenging work.

Some of the identified activities which would augment our testing capabilities are listed here:
 *  [wiki:Projects/Open/TestingImprovements RTEMS Testing] - General testing framework for RTEMS.

= Tools and Development Environment =

RTEMS applications are cross-compiled on a development host to produce executables that are transferred to and executed on target systems.  The projects in this section focus on the host side of that equation.  This means they will run on a developer's computer and possibly communicate with embedded hardware.

= Obsolete Projects =

Some projects have been proposed that are viewed as being of minor use. This list is meant to provide a way to avoid wasted effort on projects that are not widely desired. However, projects on this list might still be useful to someone, given a motivated individual to work on them.

 *  Various ideas have been proposed related to using RTEMS as a [wiki:Projects/Hypervisor  hypervisor]. The lack of protected (kernel mode) execution precludes any feasible implementations.
 *  Merge [wiki:Developer/Simulators/SimpleScalar  BSP for Simplescalar simulator]. The BSP is heavily bit-rotted and the simulator is a dead project.
 *  [http://code.google.com/p/rosetta-os Rosetta OS] [wiki:Projects/RosettaOSDeviceDriverAPI  OS Independent Device Driver API]. 
 *  Implement current version of µITRON Interface [http://www.www.tron.org/index-e.html]. itron support was removed from RTEMS due to lack of interest.
 *  More [[TBR/Delete/Libbsd-port| NIC device drivers]]. See instead [wiki:Projects/TCP/IP_update TCP/IP update].
 *  Integrate [wiki:Projects/CEXP CEXP] into main RTEMS distribution. Possible licensing issues, please apply to the RTL project instead.
 *  Scripts and documentation for creating and installing prebuilt tool packages [wiki:Building/RPM_Packages Building Tool RPM Packages], [[Building/DebianHostedTools| Debian Packages]], [[TBR/Delete/MacOSHostedTools|MacOS tools]], [wiki:TBR/UserManual/MinGW_Tools_for_Windows MinGW Tools for Windows], [wiki:TBR/Delete/Canadian_Cross_Compiler Canadian Cross Compiler].
