Some ARM gnu / newlib success to report....

Some ARM gnu / newlib success to report....

2004-10-15 by Mark Gross

I have a 14.7Mhz Olimex lpc-2124 dev board I got from sparkfun.com.

I'm using the gnu tool chain built under Linux as well as the newlib-lpc.

I built the 3.4.0 tool chain without too much trouble.

However; its taken me a bit of trial and error to get the newlib / test programs
to load and work as expected on my development board.

The following is a patch diff of what I needed to do to the newlib-lpc source files 
to get the text2.c example program to work as expected.  Its still a hack, but I thouht
I'd share it.

I'll have to make a better Makefile for myself one of these days.  As well as installing
the linker scripts and crt files in a sensible location, or perhpas an autoconf thing for 
newlib-lpc.

BTW So far I've been using the Philips flash utility on my WinXP laptop.  (is lpc21isp.c safe?)

Thanks, I'll take a look at these.

If you do, let me know and I'll incorporate it.

Seems to be.  It's pretty straightforward and I haven't heard many 
complaints about it.  I use one or the other depending on the circumstance.

It'll be a while, but I might just do it.  If I do I'll let you know.

Just gave it a try.  Works fine ;) 

Thanks!
