***  Sourcery G++ Lite 2010.09-39 for ColdFire ELF

*** Eclipse IDE
     (eclipse-cpp-helios-SR2-win32.zip)
+ C/C++ Cross compiler support and C/C++ GDB hardware debugging plugin
     (http://download.eclipse.org/tools/cdt/releases/helios)
+ Zylin CDT plugin
     (http://www.zylin.com/zylincdt)

*** Flasher HIWAVE from Codewarrior 6.3

*** proprietary board with M51FAC128C + 4.9152 MHz crystal

*** Compiler settings
In the console the invoking commande line is :
m68k-elf-gcc -O0 -g3 -Wall -c -fmessage-length=0 -mcpu=51ac -MMD -MP -MF"main.d" -MT"main.d"

*** Modified settings from the fresh install:

-> Tool Settings
C/C++ Build\Cross-Settings : "m68k-elf"
C/C++ Build\Cross-Settings\Cross GCC Compiler\Miscellaneous\Other flags :"-c -fmessage-length=0 -mcpu=51ac"
C/C++ Build\Cross-Settings\Cross GCC Linker\Miscellaneous\Linker flags : "-T m51ac128evb-rom.ld"

-> Build Steps
Post build steps command :"m68k-elf-objcopy -I elf32-m68k ${ProjName} -O srec c:\perso\eclipse\project.s19"
