MOTOROLA
The program will inform the user that it is working on converting the file
from S records to binary. This process will take from 30 seconds to a few
minutes, depending on the computer.
A prompt reading, "Comm port open?" will appear at the end of the file
conversion. This is the last chance to ensure that everything is properly
configured on the EVBU. Pressing [RETURN] will send the bootcode to
the target MC68HC711E9. The program then informs the user that the
bootload code is being sent to the target, and the results of the echoing
of this code are displayed on the screen.
Another prompt reading "Programming is ready to begin. Are you?" will
appear. Turn on the 12-volt programming power supply and press
[RETURN] to start the actual programming of the target EPROM.
A count of the byte being verified will be updated continually on the
screen as the programming progresses. Any failures will be flagged as
they occur.
When programming is complete, a message will be displayed as well as
a prompt requesting the user to press [RETURN] to quit.
Turn off the 12-volt programming power supply before turning off 5 volts
to the EVBU.
