OpenRISC 1000: uClinux 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 high performance C libraries with small footprint 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 Flextronics Semiconductor FPGA Development board, Flextronics Semiconductor SOC ASIC and on Xess XSV800 FPGA prototype board with UART, CRT VGA and AC97 audio uClibc ported networking works with OpenCores Ethernet Core writing device drivers If you would like to help with the development, please contact the developers. Download Source code of current development and stable tarball of the OpenRISC uClinux port is available from the OpenCores CVS under the module hierarchy or1k/uclinux. Source code of current development and stable tarball of the OpenRISC uClibc port is available from the OpenCores CVS under the module hierarchy or1k/uclibc. At this point no binaries for the OpenRISC are available due to hardware dependencies. However building the uClinux itself should be rather straightforward. Documentation More complex procedure is building the uClibc toolchain with gcc for uClinux applications. Such platform dependent instructions and instructions for image building can be found in the CVS under /or1k/uclinux/uClinux-2.0.x/README.or32. See uClinux and uClibc web sites 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 (AC97 controller, Opencores usb, Opencores vga, 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. Past contributor(s) These are the people currently not working on the GNU Toolchain, but have contributed in the past: Simon Srot Marko Mlinar Developers The team currently working on the uClinux and uClibc ports and device drivers: Matjaz Breskvar, phoenix@o...
