Code size for "Hello World"

[Corrin Meyer]

I am trying to compile the ubiquitous hello world application for a
ColdFire M52235EVB board and I am running into issues.  I issue the
command...

 

m68k-elf-gcc -T m52235evb-ram-hosted.ld -mcpu=m52235 hello.c -o hello

 

And I get the following errors...

 

c:/program files/codesourcery/sourcery g++
lite/bin/../lib/gcc/m68k-elf/4.2.3/../../../../m68k-elf/bin/ld.exe:
hello section .text will not fit in region ram

c:/program files/codesourcery/sourcery g++
lite/bin/../lib/gcc/m68k-elf/4.2.3/../../../../m68k-elf/bin/ld.exe:
region ram overflowed by 7872 bytes

collect2: ld returned 1 exit status

 

If I compile with the "m52235evb-rom-hosted.ld" script, it compiles but
the resultant load binary (created from the generated elf) is 40k.  I
have seen examples using the RAM hosted script which leads me to believe
that it should work (or has at least worked in the past).  I know that I
am using Newlib, but I didn't expect it to add nearly 40k of code.  Is
there a way to shrink it?
