# Makefile for building a monitor for the MPC860FADS Evaluation Board
# Note that this can be used to build a monitor destined for the boot flash
# (make) or a monitor destined for DRAM (make ram).  The DRAM version of the
# monitor is intended for use with the Macraigor BBMPC SingleStep BlackBird
# MPC interface and the startup50.mac script.
#
# If starting with a virgin FADS860 board, follow these steps:
#  1. Run "make ram" to generate the monppc.s19 file
#  2. Connect the wiggler.
#  3. Apply power to wiggler.
#  4. Start up the OCD_Commander tool.
#  5. In OCD_Commander, run the startup50.mac script.
#     This will load a ram-based monitor and start it up.
#  6. Run "make" to build the monppc.bin for flash.
#  7. With either TFTP or XMODEM transfer monppc.bin to boot flash.
#     For TFTP, just use the newmon tool.
#     For XMODEM, connect hyperterm to the bottom port (57600) and
#	  run xmodem -B; then transfer the monppc.bin file.
#
# At this point, the wiggler can be disconnected and the monitor should
# be programmed into the boot flash.
