Introduction

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

uClinux is a derivative of Linux kernel intended for microcontrollers without Memory Management Units (MMUs).

Features are:

• free, open source code with no royalty
• small code footprint suitable for embedded and portable applications
• Common Linux API
• Multitasking, preemptive scheduling
• TCP/IP networking and numerous other network protocols
• File systems NFS, ext2, MS-DOS, FAT16/32 and others

Status

• uClinux kernel working on or1ksim simulator
• It also runs on Xess XSV800 OR1200 FPGA prototype
• Writing device drivers

Download

Source code for current development tarball of the OpenRISC uClinux port is available from the OpenCores CVS under the module hierarchy or1k/uclinux. 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 uClinux port. However building the uClinux should be rather straightforward.

Documentation

No documentation available at this time. See uClinux 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.
