OpenRISC 1000 Project: RTEMS Port & Device Drivers Development

Introduction

The aim of this project is to port and maintain RTEMS to the OpenRISC 1000 family and develop device drivers for various OpenCores peripherals.

RTEMS is real-time open source operating system.

Features are:

free, open source code with no royalty
small code footprint suitable for embedded and portable applications
POSIX API and uITRON API
Scalable Architecture
Multitasking
Event-driven, priority-based, preemptive scheduling
Intertask communication and synchronization
High level of user configurability
TCP/IP networking with FTP, HTTP and other Internet daemons
File system, microwindows GUI, etc.

Status

RTEMS kernel working on or1ksim simulator
Writing device drivers

If you would like to help with the development, please contact the developers.

Download

Source code for current development tarball of the OpenRISC RTEMS port is available from the OpenCores CVS under the module hierarchy or1k/rtems. You can also get it directly by using the CVSget here.

At this point no binaries for the OpenRISC are available due to development status of the RTEMS port. However building the RTEMS should be rather straightforward.

Documentation

No documentation available at this time. See RTEMS web site for platform independent documentation.

Wish List (TODO List)

This is what we would like to develop/see developed but presently nobody is working on these projects. If you want to help, send an email to the mailing list.

Device Drivers for various OpenCores peripherals (ethernet, usb, uart etc)

If you have a suggestion for new Wish List entry, feel free to send it to the mailing list so that is added to the list and somebody may start working on it.
