README for eCos directory <PACKAGES>hal/arm/sa2sim/<VERSION>/lilmon


"Little Monitor" for Coyanosa AKA StrongARM 2 simulator - eCos version.

This directory contains files for creating a slightly altered version of
the "little monitor" - "lilmon" that Intel provided for use with the
simulator.

The change is that once the monitor has initialized the world enough, it
jumps directly to 0x8000, so you can only use this version in conjunction
with another program - such as an eCos RAM startup program that is linked
to load at 0x8000.

eCos test cases built for the sa2sim target will be thus by default.

lilmon.s is the source of the little monitor.

lilmon.lnk is the linker script to create the elf-format "executable."

lilmon.elf is the executable to give to the simulator.

COMPILECOMMAND contains the text of a compiler invocation to build
lilmon.elf, in case you decide to experiment for example with a different
entrypoint to the eCos app.  It contains

	arm-elf-gcc -nostdlib -Tlilmon.lnk -o lilmon.elf lilmon.s

which does the obvious thing.  (It's neither a script nor a makefile, just
a one liner for pasting into the commandline)


For information on invoking the simulator, see the README in neighbouring
directory "simcfg" where simulator config files and scripts tailored for
running your eCos application (along with lilmon.elf) are presented.
