OpenRISC 1000: NEW GNU Toolchain Port Introduction This project is to port and maintain GCC, GNU Binutils, uClibc, Busybox, Linux, GDB for the OpenRISC 1000 family (OR1200 processor). GCC is a GNU Compiler Collection that includes the ANSI C Compiler, C++, Java, Fortran and other compilers. All compilers produce excellent code and are often used in commercial products. GCC is free software with full source code available. GNU Binutils are a collection of binary tools. The main ones are: ld - the GNU linker. as - the GNU assembler. uClibc is a C library for developing embedded Linux systems. BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. GDB, the GNU Project debugger, can do four main kinds of things (plus other things in support of these) to help you catch bugs in the act: Start your program, specifying anything that might affect its behavior. Make your program stop on specified conditions. Examine what has happened, when your program has stopped. Change things in your program, so you can experiment with correcting the effects of one bug and go on to learn about another. Status In order to make it easier to install all necessary tools for the OR1200, a script has been created to install the whole toolchain. The following versions are included in the toolchain: GCC-4.2.2 uClibc-0.9.29 Busybox-1.7.5 Linux-2.6.19 or1ksim-0.2.0rc2 (OpenRISC 1000 architecture simulator) We have kept the old "toolchain"-website as a reference for now, here is a link to the "old" version. Old version If you would like to help with the development, please contact the developers. Download The installation script can be downloaded here Please note that provided binaries have not been extensively tested. Installation This toolchain script has been tested under Debian "Lenny" "Etch" x86, Debian "Lenny" PPC, Ubuntu Linux, and Red Hat Enterprise Linux AS release 4 (Nahant Update 4), OpenSUSE 10.2 & 11.0 Please let us know if you have success with another package. The procedure to build and install the toolchain is the following: You need to install the following packages in order to be able to build the toolchain: sudo apt-get update sudo apt-get -y install build-essential sudo apt-get -y install make sudo apt-get -y install gcc sudo apt-get -y install g++ sudo apt-get -y install flex sudo apt-get -y install bison sudo apt-get -y install patch sudo apt-get -y install texinfo sudo apt-get -y install libncurses-dev Download the script and place it in a suitable location. Start the script as root (sudo sh MOF_ORSOC_TCHN_v3b.sh) Then you can take a coffee break............ Documentation See online documentation at the following sites: GCC documentation GNU Binutils documentation GDB documentation Tutorial how to use OR1200, JTAG development i/f and gdb to connect to openrisc HW target. Credits go to Resarch Group Digital Techniques, Hogeschool voor Wetenschap & Kunst, Campus de Nayer SW tutorial local copy of the PDF and possibly updated version at the original site see also HW tutorials at OpenRISC 1200 page Wishlist 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. Port of the toolchain to 64-bit part of OpenRISC 1000 Write optimized versions of routines in Newlib instead of using generic ones Test the tools on non-Linux platforms (various UNIX and Cygwin) Provide instructions how to build and install the GDB 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. Additional Software Develpment Tools We are currently testing Source Navigator and GDB Graphical User Interface DDD and Insight. So far they both appear to work fine.
