MCF5223x gcc cross compiler under Linux/x86_64

I'm looking for instructions on how to build a gcc based cross
compiler for MCF5223x under Linux/x86_64 (gentoo in my case)?

Thanks
Petter

You might want to check out "crosstools" by Dan Kegel. It is a set of
scripts that builds various revisions of gcc toolchains for various
architectures. Even if it doesn't do exactly what you want, you could
try following the scripts to see how it's done. Good luck...

I've build cross compilers from gcc previously (both m68k and ppc
targets), but it appears that m68k is no longer a supported target for
binutils (at least no on x86_64):


$ tar xvfz binutils-2.17.tar.gz 
$ cd binutils-2.17
$ ./configure --prefix=/usr/local/scratch/petter/coldfire/ --target=m68k-coff
$ make

Which results in:

checking whether byte ordering is bigendian... no
This target is no longer supported in gas
make[1]: *** [configure-gas] Error 1

But if I try to compile old versions of binutils (e.g. binutils-2.9.1)
on my x86_64 I get:

Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized

So I'm looking for a version of binutils (or more correctly gas) which
support a m68k target on an x86_64 platform?

You might find it easier to get the package from CodeSourcery:

http://www.codesourcery.com/gnu_toolchains/coldfire/index_html

They've got pre-build linux tarballs, and also a tarball of the source 
code if you want to do it yourself (to get 64-bit binaries, for 
example).  They are pretty much the "official" maintainers of the 
ColdFire gcc port (i.e., they are supported by Freescale, and work 
closely with the FSF).  I haven't downloaded their code myself (I'm 
using a home-built setup from about a year ago), but I'll get round to 
it sometime.

Of course, you learn far more by building the toolkit yourself with the 
help of websites here and there, and you can customise it (you want 
binary constants of the form 0b01100101?  Just merge in the patch from 
avr-gcc into your ColdFire gcc build tree...)

Thanks David. That will at least tell me which version of the tools
supports m68k cross compilation.

The codesourcery tarball is great. I've managed to build and run a
hello world style application. However, in order to do utilize the
features of the 52235 I need to obtain header files for all the
registers, bit-fields, and some libraries like a tcp/ip stack. 

I've seen some people suggesting to use the CodeWarrior header files,
but they seem to have a different run-time library and link scripts,
which has to be ported. Does anybody know if this has been done
already? I don't want to reinvent the wheel...
