[Efi332] Standard GNU C library for CYGWIN

[David Eicher]

Hi Kevin,

 

Yep, I'm not aware that a library exists for SCI either. So.., it looks like
I'm going to build one. One thing I struggle with is, use SCI or QSCI? My
ultimate goal is to be using QSCI with interrupts. But that might be a bit
much to hope for initially. Maybe I'll try to walk before I run, and just
use basic character puts and gets. Then, when I'm more familiar with the
process of building a library (never done it), I'll go for the more powerful
approach.

 

That is nice to know that the stdlib with GCC is so big, gotta stay away
from that!

 

Thanks,

 

Dave

Dave,

 

I haven't built GCC for the 555 but I have re-built GCC for the 332 many
times and I have found that newlib is much better than stdlib that comes
with GCC.  For example if you build the 332 source code on Sourceforge with
the newlib it's almost half the size of stdlib.  As far as printf() I have
seen a number of versions for embedded work but you would be required to
build from source in order to use it.  I don't know of anything that's ready
to work with SCI out of the box.

Hello list,

 

Has anyone built a standard C library for the GNU C running on cygwin? I'm
looking for the prinf( ) function (and others), that have been re-directed
to the SCI serial interface for MPC555/565.

 

Thanks,

 

Dave
