Re: Building for custom 68k or ColdFire board without OS?

[Mark Powell <medp at primagraphics dot co dot uk>]

We use the development environment you are proposing and it works 
extremely well.
I built a cross tool-chain that supports the m68k family and ColdFire (I 
built it on Intel/Linux, Sparc/Solaris and HPUX hosts) and used that to 
compile newlib (http://sources.redhat.com/newlib/). Newlib has separate 
C and math libs.
I wrote some low-level routines (in C) that newlib calls to do serial 
port i/o to the UART and voila we had printf, getchar, scanf etc on a 
TTY console.
I then extended the serial i/o driver to use interupts and buffer 
characters and this provides a sort of background i/o capability for 
diagnostic menus on the TTY console.

The only thing is, it's not packaged up with an idiots guide that 
requires no previous knowledge. You should expect to understand the 
workings of the toolset and how to generate ROMs etc.
