as you might guess from the subject: I'm trying to find a toolchain for
freescale's hcs12 or S12X family of microcontrollers. Currently i'm
using Codewarrior on the Windows machine at work, but as i'm a tad
dissatisfied by it's lack of decent syntax-checking and have no windows
at home, i'd rather use some free compiler available for my rather
unusual platform (Linux on PowerPC). So gcc would probably be the best
bet.
Has any of you guys experience with that combination or another
suggestion (apart from buying some windows machine)??
Building a toolchain isn't too hard. Below is the shell script
I used last time I built a toolchain for the 6812. That was
probably a couple years ago I included newlib in my build, but
IIRC, you can build a 6812 compiler without any libc at all if
you prefer.
