Building a GNU Cross tool-chain for AVR32

AVR32 is a 32-bit RISC processor architecture. Atmel AVR 32-bit Toolchain is based on the GNU toolchain. We propose to build a cross tool-chain for the AVR32 target, with the help of Crosstool-NG 1.20.0 and patches from there. We provides you a tarball with all the necessary material inside: Crosstool-NG 1.20.0, GNU tool-chain sources, patches, configuration files, scripts,…

1. What you get after the build ?

You get a GNU cross tool-chain for AVR32/Newlib:
  • GNU GCC 4.4.7 C/C++ compiler (gcc, g++,…)
  • GNU binutils 2.22 (objdump, readelf,…)
  • Newlib Standard C Library (newlib) 1.20

2. Requirements

  • A Linux host machine (may work on other Un*x machines)
  • The following tools: grep, sed, bash, cut, install, make, gcc, awk, bison, flex, makeinfo, automake, libtool, stat, curl, cvs, patch, tar, gzip, bzip2, lzma, readlink, binutils, ncurses, expat
  • make 3.82 (may not work with make 3.81)

3. Get the material

Download that tarball. It contains all the necessary material (scripts and source codes) to get a working GNU cross tool-chain for AVR32.

4. Uncompress the tarball

$ tar zxvf crosstool-source-v4.tar.gz

5. Build the cross tool-chain

Run the building script:
$ cd crosstool-source-v4
$ ./build.sh all avr32

Be patient...the process of building the cross tool-chain is very long. Once finished, the cross tool-chain is in avr32 sub-directory.

Highlights

Acknowledgments

Digiteo
We would like to thank Digiteo that supported us in making the UNISIM virtual platforms available to the community.

Exhibition

HiPEAC
We presented a poster at the poster sessions of the HiPEAC'12 conference, January 23-25, 2012, Paris, France. The HiPEAC conference provides a forum for experts in computer architecture, programming models, compilers, and operating systems for embedded and general-purpose systems. The conference aims at the dissemination of advanced scientific knowledge and the promotion of international contacts among scientists from academia and industry.

On-going evaluation

OPEES
A UNISIM virtual platform of a Xilinx Virtex-5 FXT is being evaluated by project partners in the context of OPEES (Open Platform for the Engineering of Embedded Systems), a European project that aims to ensure long-term availability of critical / embedded systems engineering technologies to secure industry competitiveness and development.
