How To Generate MPC555 Cross Compiler Tools

Preambule

This HOWTO is OK with gcc v4.4.4

Make sure the mpc555.ld file you use sets the following variables :

        SDA2_BASE_ = .; 
        just before *(.sdata2) section and 
        SDA_BASE_ = . ; 
        just before *(.sdata) section 

Make sure these tools are installed on your system : bison, flex, m4, makeinfo (texinfo package), mpfr (libmpfr-dev package)

Information about building cross compiler

• http://www.kegel.com/crosstool/
• http://ecos.sourceware.org/build-toolchain.html

Packages to retrieve

• binutils-2.20.1
• gcc-4.4.4
• newlib-1.18.0

Prepare the generation

• Check that on your host a gcc compiler is installed
• Set sh as shell (important to build gcc)
• Set these variables :
  • Work directory : export CROSS_PRJ=$HOME/MyDirectoryForMPC555
  • Directory where cross compiler tools will be installed : export PREFIX=$CROSS_PRJ/tools
  • Set PATH variable : export PATH=${PREFIX}/bin:${PATH}

Package binutils

cd $CROSS_PRJ
tar xvfz /DIRECTORYXX/binutils-2.20.1.tar.gz
mkdir build-binutils
cd build-binutils
CC=gcc
../binutils-2.20.1/configure --target=powerpc-linux
    --prefix=$PREFIX
    --with-newlib
    --disable-werror
make all
make install

Package GCC

cd $CROSS_PRJ
tar xvfz /DIRECTORYXXX/gcc-4.4.4.tar.gz
mkdir build-gcc
cd build-gcc
../gcc-4.4.4/configure --target=powerpc-linux
     --prefix=$PREFIX
     --with-newlib
     --without-headers
     --enable-languages=c
make all-gcc
make install-gcc

Package newlib

cd $CROSS_PRJ
tar xvfz /DIRECTORYXXX/newlib-1.18.0.tar.gz
mkdir build-newlib
cd build-newlib
../newlib-1.18.0/configure --target=powerpc-linux
                              --prefix=$PREFIX
make all
make install

May be you will get an error because of makeinfo command.

To correct that, check where is your makeinfo command, edit Makefile and change line containing MAKEINFO = path-to-build-newlib/missing makeinfo

Test the crosscompiler

A way to check the powerpc-linux-gcc croscompiler is to launch : powerpc-linux-gcc --version

And check that the result is : 4.4.4
