Communication between PC and FLASHER
Make sure the power supply is connected (one of FLASHERs LEDs should be illuminated) and FLASHER is connected to your PC
with a NULL-modem cable as supplied. If the PC-program displays anything other than "No communication" under flasher
status, the communication between Flasher and your PC is functioning.
First time setup of FLASHER When using FLASHER for the first time, please select the menu point Options->Device. You will see the following dialog box:
First carefully select the correct target device. A false selection may
damage your target! Then select the chip area you would like to access,
the sectors of the on chip-flash and the interface you would like to use.
The serial interface requires a cable to connect FLASHER to your target.
For targets running at low frequencies, it may be necessary to set the speed
option to Slow.
Now you should be able to blank check, clear, program, verify or read the target
chip in serial mode (if your target is properly connected to the FLASHER). The
first time you program or verify, the PC downloads your your target program to
the FLASHER, where it is stored in the on board FLASH chip for programming or
verification. The PC-Program stores all setup information in the registry; when
you start the program the next time, it will start with the same settings.

Programming/clearing/verifying/blank check
Select one of the commands in the TARGET menu to start the operation.
Note that some of the menu points may be grayed if you have no connection to the target or no file loaded
A modal dialog box will indicate the status and progress of the operation;
the operation can be canceled hitting the CANCEL button
SETUP
The operating mode of FLASHER may be changed using the setup dialog from the Options menu.Power up
mode, Power down mode and Reset mode should not be changed for normal operation. Setting of Power down mode has no
effect on FLASHER ST7.You may change the reset active and reset inactive time, if required by your target hardware.
All setup settings are stored permanently in FLASHER after pressing 'Save setup' button.
Additional options
The operating mode of FLASHER may be changed using the setup dialog from the Options menu.Power up
mode, Power down mode and Reset mode should not be changed for normal operation. Setting of Power down mode has no
effect on FLASHER ST7.You may change the reset active and reset inactive time, if required by your target hardware.All
setup settings are stored permanently in FLASHER after pressing 'Save setup' button.
Operating FLASHER in stand-alone mode
After download the target program is stored in FLASHERs on board Flash
memory until
FLASHER is reconfigured for an other target, or an other target
application program is downloaded to FLASHER. Any number of
microcontroller may then be programmed by FLASHER
(one at a time) without the need of a host PC, by simply pressing the
start button. FLASHER will use the settings
which have been made in the PC-program. This includes the selection of
the sectors of the FLASH and the interface.
The progress and the result of the operation is indicated by the LED:
Status of LED
Meaning
GREEN, flashing

GREEN
Programming operation successful
RED
Programming operation failed
Remote control of FLASHER ST7
FLASHER ST7 can be remote controlled by automated testers without the need of
a connection to PC and Flashers PC program. Therefore FLASHER ST7 is equipped
with additional hardware control functions, which are connected to the SUBD9
male connector, normally used as RS232 interface to PC. The following diagram
shows the internal remote control circuitry of FLASHER:
ASCII command interface
FLASHER with firmware version 1.84 or above can be
controlled without the need of Flashers PC program. FLASHER firmware
contains an ASCII command interface function. Any application may send
commands via RS232 to Flasher to start programming of target CPU.
A manual which describes ASCII command interface can be downloaded from our downloadpage.
Using the serial link to program in circuit
FLASHER can be used for in circuit programming of ST7 CPUs, which
incorporate built in firmware for serial update of user flash. The
target system has to be designed to support this mode of operation.
Serial programming, technical details
Serial programming of ST7 microcontrollers uses ICC protocol.
The commands which are used are described in the ST manual. In general, the sequence is as follows:
FLASHER resets the target CPU and then sets up the target to enter ICC mode
FLASHER downloads an application program (RAMCODE) to target CPU.
FLASHER starts the target RAMCODE
RAMCODE accepts commands from Flasher to read, clear or program the target CPU
Error messages
The following error messages can occur during operation of FLASHER (shown in red on your PC)
Code
Error messages
Meaning/remedy
1
Erase failed
Erase operation has failed.
2
Write failed
Write operation has failed.
3
Verify failed
Verification failed. Loaded program and contents of the flash-memory are not identical.
4
Blank check failed
Chip is not blank.
5
Flash write/erase timed out
Could not write into flash memory, the max. waiting time has been exceeded.
7
Canceled
Last operation has been canceled by the user.
51
VCC fail
VCC of target system outside specified range.
Check supply of your target system
55
CRC check in programmer failed
After download or after programming of target CPU, the CRC of Flashers memory changed.
Check supply of Flasher to avoid problems
56
Internal VCC drop during operation
Check Flashers power supply
58
DAC for Vpp not calibrated
Flasher is unable to build VPP for Target CPU, because Calibration data for DAC was lost.
75
RAMCode does not work
After download to target, the RAMCode did not respond to Flasher.
Check device configuration.
76
RAMCode does not respond command
RAMCode did not respond to Flashers command.
Reset target and retry operation.
80
Could not enter ICC mode
Target did not enter ICC mode.
Check configuration and device settings.
Check target connection.
81
Timeout during serial data transfer
Target did respond in specified time.
Check configuration and device settings.
Check target connection.
82
Option byte read failed
Retry operation.
Check configuration and device settings.
Check target connection.
83
Option byte programming failed
Retry operation.
Check target connection.
If target was read protected, Option bytes can not be modified.
Select "Clear All" function first.
84
Program All function failed
"Clear All" function terminated in error. Retry operation.
Check target connection.
85
Target is read protected
Target could not be read, because target is read-protected by option byte settings.
Trouble shooting
Proper
operation of FLASHER in serial mode depends on your target system. If
you have any trouble operating FLASHER in serial mode, please:
Check your target hardware
Check the connecting cable
Use an oscilloscope to check the state of the signals on the target connector,
especially to check if the target CPU is RESET properly and the target CPUs ICCCLK and ICCDATA signals work properly.

Updating FLASHER's software
FLASHER contains a microcontroller with flash memory and a boot loader. FLASHER's
firmware can be updated using the serial interface of any PC by starting the Flasher
software and select the "Options | Download Firmware" menu.
