#
# Basic, target/architecture independent makefile for building an
# application that runs on its own stack.
# The application code in main.c provides a target-independent example
# of hooking up an application to a target running MicroMonitor.
# Also, there is a self-induced exception branch (see strace_demo.c)
# that can be invoked to force the application to take an exception.
# The purpose of this is to allow the user to then use the monitor's
# 'strace' command to see the function nesting that occurred prior to
# the exception. This requires that the symbol table also be on-board.
# To walk through this example, establish the site-dependent information
# specified below, then execute "make" to build the image, and then
# "make dld sym" to install it (and a symbol table) on the target.
#
# Site dependent information:
# Adjust these values based on your system configuration.
# ARCH:
# Set ARCH to one of the accepted CPU architectures (i.e. MIPS
# PPC, ARM, BLACKFIN, COLDFIRE, MICROBLAZE).
# MONCOMPTR:
# Set MONCOMPTR to the output of 'echo $MONCOMPTR' on your target.
# APPRAMBASE:
# Set APPRAMBASE to the output of 'echo $APPRAMBASE' on your target.
# TARGET_IP:
# Set TARGET_IP to the IP address of your target.
#
ARCH = ARM
MONCOMPTR = 0x10000020
APPRAMBASE = 0x20100000
TARGET_IP = 192.168.1.242
