Renesas M16C-Flasher User manual

M 1 6 C - F l a s h e r – F i r s t S t e p s
General
The M16C-Flasher is a tool for the programming of Renesas-microcontroller. It uses the Standard
Serial Mode 2 (as nc), this means ou onl need a serial cable between pc and microcontroller.
There is no additional hardware required.
Keep care for the different voltages of the pc-comport (+12V & -12V) and the microcontroller (5V &
0V). Use a MAX232 or something simular.
The NON-PROFIT version of the M16C-Flasher is free for private, non-commercial use onl .
Otherwise ou have to purchase a license.
Help
Most of the function are selfexplaining. There are tooltips for most buttons and options, so it
should be eas to use.
This manual shows onl the first steps with the M16C-Flasher. It explains some basic functions
and problems.
First Start
You have to set the comport and baudrate. ('Settings'). The maximum baudrate depends on the
microcontroller and the quartz-frequenc . For the first test, I suggest 9600 baud.
Select protocol 'Revision 2' and 'Standard Connect'. (Like suggested in actual datasheets.)
If ou use the Control-Lines for Reset and CNVSS, ou have to keep care for the correct logic.
(see also 'Control-Lines' in this manual)
Select the microcontroller...
Connect
Before ou can do an function (programming, erasing, reading,...), ou have to connect with the
bootloader of the microcontroller. If ou don't use the Control-Lines, ou have to set CNVSS and
make a reset of the mikrocontroller, to enter the bootloader mode.
Press 'Connect' and the M16C-Flasher tries to establish a communication to the bootloader
program of the microcontroller. The M16C-Flasher displa s the version of the bootloader
(VERx.xx), if it was successful.
Now ou can perform the function (e.g. programming).

ID of microcontroller
The microcontroller is protected b a 7 b te ID. Without the correct ID, it is not possible to read,
write or erase the flash memor .
The NON-PROFIT version of the M16C-Flasher onl writes the ID 0x00 0x00 0x00 0x00 0x00
0x00 0x00, so there is no protection.
You have also the option to log all used IDs into a file (ID.LOG)
B default the M16C-Flasher uses the last working ID. This is useful under most conditions.
But if ou are working at different devices with different IDs, ou should select 'Extract ID from
File.
'ID mismatch' - Error
If the ID of M16C-Flasher doesn't match the ID of the program in the microcontroller, ou will get a
'ID mismatch'-error. Insert the correct ID, turn off and on the power suppl of the microcontroller
and tr again.
If ou don't switch off the power suppl , the ID-test will fail again. This is a protection against the
'bruce force' method to hack the ID.
Option 'Load File once'
You want to program to same file more often and ou don't want to select the same file again and
again in the 'Open'-dialog?
Just select the 'Load File once' option and ou have to select the file onl one time. The next time
ou press on 'Prog', it won't ask again...
Control-Lines
You want to make the programming more eas , ou don't like the manual reset and setting of
CNVSS?
The M16C-Flasher support the use of the control-lines RTS & DTR. With these lines ou can reset
the microcontroller and set it into the bootloader mode.
You find an example in the 'Setting' of M16C-Flasher.
To make the control-lines independent of our used logic, ou can invert each signal.
Keep care of RDY & HLD, if ou use the external bus.
AutoFlash-Function
To make programming as eas as possible the M16C-Flasher has the AutoFlash-function.
Just program a MOT file once and the M16C-Flasher looks for changes of the file in the
background. So if ou recompile our project, the M16C-Flasher starts programming
automaticall .
