BUILDING PROGRAM:

For example (building for cqsh3)

	$ ln -sf config/config.mk-sesh3 config.mk
	$ ln -sf config/config.h-sesh3 config.h
	$ make


WRITING PROGRAM INTO FLASH (for Solution Engine):

To write this program (sh-stub.srec) to the Flash ROM of Solution
Engine, I use "minicom" and "ascii-xfr.  Here are the setting:

------------- /etc/minirc.dfl
# Machine-generated file - use "minicom -s" to change parameters.
pr port             /dev/ttyUSB0
pu baudrate         115200
pu bits             8
pu parity           N
pu scriptprog       /usr/bin/runscript
pu minit            ~^M~ATZ^M~
pu mreset           ~^M~ATZ^M~
------------- ~/.minirc.dfl
# Machine-generated file - use setup menu in minicom to change parameters.
pu pprog9           /usr/bin/ascii-xfr -dsv -l 10
pu baudrate         115200
pu updir            /home/niibe/work/ipl+g
-------------

Booting with Hitachi ROM monitor (SW-4-3 is "ON"), then invoke the command: 

	Ready > fl 80000000

Then, type "Ctrl-A S", select "ascii" transfer, and specify the
filename to send.

	Ready > fl 80000000
	Flash ROM data copy to RAM
	Please Send A S-format Record
	complete
	Program :complete
	Flash write complete 
	Ready >
