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?)
