Building a GNU Cross tool-chain for MPC7450

MPC7450 is a 32-bit PowerPC G4 processor from Freescale. PowerPC processors on Linux are well supported by the GNU tool-chain and Crosstool-NG. We propose to build a cross tool-chain for the powerpc-7450-linux-gnu target (i.e. an MPC7450 host machine running Linux), with the help of Crosstool-NG 1.20.0. With that cross tool-chain, you can for example build applications for Linux, a BusyBox environment and a Linux kernel for MPC7450. We provides you a tarball with all the necessary material inside: Crosstool-NG 1.20.0, GNU tool-chain sources, configuration files, scripts,…

1. What you get after the build ?

You get a GNU cross tool-chain for Linux/MPC7450:
  • GNU GCC 4.8.2 C/C++ compiler (gcc, g++,…)
  • GNU binutils 2.22 (objdump, readelf,…)
  • GNU Standard C Library (glibc) 2.19.0
  • GNU debugger 7.6.1 (gdb)
We followed these instructions with the following Crosstool-NG 1.20.0 configuration at step 5 (only changes are shown):
Target options --->
  Target Architecture (powerpc) --->
    (7450) Emit assembly for CPU
    (7450) Tune for CPU
  Floating point: (hardware (FPU)) --->

Toolchain options --->
  (7450) Tuple’s vendor string

Operating System --->
  Target OS (linux) --->
  Linux kernel version (3.14.11)

Binary utilities --->
  binutils version (2.22) --->

C compiler --->
  gcc version (4.8.2) --->
  [*] C++
  [ ] Link libstdc++ statically into the gcc binary

C-library --->
  C library (glibc) --->
  glibc version (2.19.0) --->
  (-mno-altivec) extra target CFLAGS
  (-g) gcc extra flags

Debug facilities --->
  [*] gdb --->

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 MPC7450.

4. Uncompress the tarball

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

5. Build the cross tool-chain

Run the building script:
$ cd crosstool-source-powerpc-7450-linux-gnu-v4
$ ./build.sh all

Be patient...the process of building the cross tool-chain is very long. Once finished, the cross tool-chain is in powerpc-7450-linux-gnu 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.
