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
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

1> p 4 0x10 0x100 0x10000
4       16      256     65536

2> function cmds.x(a, b) return string.lower(a)..b end

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:

then go to 'quick start document'

Then the section 'download the tools'

    the m68k-elf toolchain

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.
