Driving Boot Mode from a Personal Computer
Operation
Configure the EVBU for boot mode operation by putting a jumper at J3. Ensure that the trace command
jumper at J7 is not installed because this would connect the 12-V programming voltage to the OC5 output
of the MCU.
Connect the EVBU to its dc power supply. When it is time to program the MCU EPROM, turn on the
12-volt programming power supply to the new circuitry in the wire-wrap area.
Connect the EVBU serial port to the appropriate serial port on the host system. For the Macintosh, this is
®
the modem port with a modem cable. For the MS-DOS
computer, it is connected to COM1 with a straight
through or modem cable. Power up the host system and start the BASIC program. If the program has not
been compiled, this is accomplished from within the appropriate BASIC compiler or interpreter. Power up
the EVBU.
Answer the prompt for filename with either a [RETURN] to accept the default shown or by typing in a new
filename and pressing [RETURN].
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.
