Hi Mike,
Just last weekend, I compiled Lua for the ColdFire 5282 with the
GreenHills tools and ran it on a M5282lite evaluation board.
I've just tried compiling it with the m68k-elf-gcc and it compiles
with these flags:
MYCFLAGS= -m5200 -msoft-float
MYLDFLAGS= -m5200 -msoft-float -nostdlib -Wl,-elf2flt
-L/usr/local/m68k-elf/lib/m5200/
MYLIBGCC=$(shell gcc --print-libgcc-file-name)
MYLIBS= -lutil -liberty -lc $(MYLIBGCC) -lc
Here is a tar gz file base on Lua-5.1-work6 with current patches, plus
my hex numbers patch, minus the math library, plus a command line hook
so you can have a table of commands to work like this:
pshook@pshooklt:~/lua/src$ ./lua -i ../test/cmd_hook.lua
Lua 5.1 (work6-cumulative1) Copyright (C) 1994-2005 Tecgraf, PUC-Rio

3> x 'ONE' 'two'

If you ever need to install the GNU tools for ColdFire, the easiest
install I've seen for Linux is here:
http://www.uclinux.org/get_started/
then go to 'quick start document'
http://www.uclinux.org/get_started/uClinuxbeginner.html
Then the section 'download the tools'
the m68k-elf toolchain
http://www.uclinux.org/pub/uClinux/m68k-elf-tools/m68k-elf-tools-20030314.sh
This installs the binaries directly without having to compile. It
works on Debian too.

I want to get Lua to run on Ed Sutter's uMon

He supports many boards. The one in this directory
umon/umon_ports/csb360 is for the ColdFire 5272 which is really close
to the ColdFire 5282.
