1 GETTING STARTED
1.1 GENERAL
The TFP2 Flash Programmer, Model TFP 2 provides a stand-alone, FLASH memory programming tool for
Teridian Semic onduc tor’s embedded controller s. The TFP 2 facilitates FLASH programmi ng in a
manufacturing production environment requiring minimum ancillary equipment. Once the TFP2 has been
initializ ed with the target’s program code, the target’s FLASH memory can be programm ed either
manually vi a operator push button, or controlled vi a a factory automation computer (ATE).
The target’s program c ode is stored in a standard 32-pin PLCC 256 KB x 8 Flash PROM (EEPROM). A
RS-232 interface is provided for connection to a PC allowing for downloading of the target’s program
code to the TFP2’s internal E E P ROM. Thi s downloadi ng utility along wit h target programming and
additional status information is provided v ia a simple text based user interface.
The TFP2 supports target flash memory sizes of: 8KB, 16KB, 32KB, 64KB , 128KB, and 256KB.
Once the TFP2’s internal E E P ROM is programmed, the PC may be removed for standalone operation.
Standalone operat ion only performs the target F LASH mem ory progr ammi ng. Once programmed, the
target’s FLASH mem ory contents are verified and a PASS or FAIL indication is reported. The TFP2 front
panel incorpor ates two status LEDs. These status indications are also provided at the ATE connector
and displayed by the P C User Interface.
Two target connector s are prov ided to facilitate custom target c onnec tions. The standard ADM-51 ribbon
cable connector is provided along with a discrete wire connector . The discrete wire connector
accommodates low cost, custom cable harnesses. These two cable connector interfaces are hardwired
together and are not two separate interfaces.
1.2 SAFETY AND ESD NOTES
Standard ESD handli ng pr ec autions should be employed whenev er handli ng electronic equipment. The
TFP2 Flash Programmer utilizes ESD protection devices on its cable interfaces. Potential equipment
damage and/or malfunction is possible if work surf ac e groundi ng pr oc edur es are not incorporated.
Revision 2.3 5 of 36
The TFP2 ESD protection devices do not protect the target’s hardware. Correct
handling procedures and proper work area grounding minimizes damage to all
equipment!

2.1 TFP2 CHKSUM.EXE UTILITY
Prior to downloading the target’s hex file to the TFP2, the target’s hex file must be preprocessed using the CHKS UM.E XE uti li t y pro vid ed with the enclosed diskette. A hex file
not processed with CHKSUM.EXE will resu lt in incomplete programming of the target’s
FLASH memory. The target’s code must be of the Extended Intel ASCII HEX-80 format for
processing by CHKSUM.EXE.
From the DOS Command prompt, inv ok e CHKSUM.EXE as follows:
chksum kb <infile.hex >outfile.hex where:
kb = desired file siz e, Mem or y Size S witch setting to be used during TFP2 downloading and
target programmi ng
infile = t ar get code hex file to be processed
outfile = processed t ar get code hex file to be downloaded to TFP2
The following fi gur e shows a typical invocation of CHKSUM.EXE:
Figure 2-1: CHKSUM.EXE Hex File Processing
The purpose of the CHKSUM utilit y is to or ganize the individual hex records into a contiguous “sequential
address increasing” structure. Some complier s produce non-sequ ential hex files. T he TFP2 assumes a
sequential file struct ur e. A non-sequential hex file downloaded to the TFP2 resul ts in missing bytes (the
missing bytes are the out -of-sequence hex records) in the target flash memor y (when the target is then
programmed wit h the TFP 2).
The CHKSUM.EXE utility m ay or may not ov er write the last four bytes of the downloaded target hex file
depending on whether these l oc ations are used or not.
Revision 2.3 7 of 36
Page 8
Flash Programmer Model TFP2 User’ s M anu al
The following cases apply to using the CHKSUM.EXE utility:
1. If the last four byt es of the t ar get hex file are unused (0xFF), the CHKSUM.EXE uti lity will insert
its own calculated t wo byte CRC and two byte checksum.
2. If any of the last four byt es of the t ar get hex file are non-0xFF values, the CHKSUM.EXE utility
will NOT overwrite the four original values.
The CHKSUM.EXE utility displ ay s the following warning when it encounters non-0xFF values:
Figure 2-2: CHKSUM.EXE Warning Display
When programmi ng the target FLAS H m em ory, these last four bytes of the target hex file are transf er r ed
intact. Either the CHKS UM.E XE calc ulated CRC and checksum bytes are copi ed or the ori ginal target’s
hex data are copied. If the last t wo bytes of the target hex file are 0xFF (CHKSUM not used), t he TF P 2
overwrites the last two 0xFF bytes with its calculated checksum dur ing the Hyper-Terminal file Download
operation.
With HyperTerminal configured for serial COM port, 38400 baud, 1 stop bit, no parity, XON/X OF F ( refer to
Section 3.3 for serial communic ation setup information) the following inform ation is displayed upon
applying power to t he TFP2. Any generic termi nal emulation program will work. Howev er , the target hex
file download instr uc tions presented apply to HyperTerminal.
Figure 2-3: TF P 2 Powe r -Up Information Display
The Memory Size Switc h setting and the checksum of the current target fil e stor ed in the TFP2’s internal
EEPROM are displayed. An “I nv alid M em or y Size setting” m essage appears if the Memory Size Switch is
set to one of the invalid positions. Rotate the Memory Size Switch to a proper setting and re-apply power
to the TFP2 to update the Memory Siz e setting.
If the target hex file has non-FF values in any of the last four bytes, t he abov e power-on screen m ay
display a “TFP2 EEPROM verification er r or .” message. The displayed “TFP2 EEPROM Checksum =”
value and “Stored Checksum =” value will be different. This occurs when the stored check sum value
(from user’s target fi le) is derived from a different c hec ksum c alc ulation from what the TFP2 uses.
Therefore, the TFP 2 c annot confirm the EEPROM’s contents. Howev er, the chec k sum verification error
will not prevent the TF P 2 from programming a target board. The “TFP2 EEPROM Checksum =” value is
recalcul ated upon every power-on or system reset. Manual verification of the EEPROM’s contents
requires compari ng the TFP2 EEPROM Checksum value derived after the file download to subsequent
power-on recalculated checksum values. See Figure 2-8 for an example of a display ed c hec k sum value
after a file download.
Upon pressing the “Ent er ” key , the “>” charac ter is displayed indicating the TFP2 acknowledges the PC’s
keyboard. Typing “ ?” followed by the “ E nter” key displays the Help Menu.

Commands C, E, T, V, Z and ? are single keystroke events (no further user acti on requi r ed until the TFP2
completes the int ended task). The D, H and P commands require additional user action and are
described in Section 2.6, Section 2.2, and Section 2.3, respectively. The BOOT command is a special
user action and is descri bed in Section 5.
The following t ables show the results of the last two words of the hex file after usi ng CHKS UM and after

2.2 TFP2 EEPROM DOWNLOAD
Transfer of the target’s code from a PC to the TFP2 begins with the “H” command. The target code file
must have been preprocessed using the CHKSUM.EXE utility pr ov ided on the enclosed diskette. Refer
to Section 2.1 for instructions on using CHKSUM.EXE. Use of any other format results in m alfunction and
download checksum er r or s.
After typing “H” followed by the “Enter” key, the cursor m ov es to the following line. Next, click on the
“Transfer” button and scroll down to “Send Text File” to select t he desired f ile to be downloaded.

EERPOM. The running CRC calculated during the file download is compar ed to the embedded CRCs of
the indivi dual byte r ec or ds within the hex file for appropri ate PASS and FAIL indication. Additi onally, the
appropriate green or r ed LE D is ill umi nated. The TFP2 EEPROM checksum calculation value is based
on the memory size switch setting and is displayed for future reference. The download transfer times
may vary from 15 minutes to 1 minut e for a 64 KB fil e size. The Microsoft
Windows 2000 Service Pak 4
or later affor ds the faster download time.
Figure 2-8: TFP2 Download Complete
Possible reasons for a FAIL indication upon downloading a fi le to the TFP2:
1. Downloaded file not Intel Hex format.
2. USB to RS-232 dongle communicati on pr oblem (i nc r ease Line del ay to 10 msec.).
3. USB to RS-232 dongle does not support XON/OFF .
4. XON/XOFF protocol f ailure, close and restart Hyper-Terminal.
5. Hex file not converted using the CHKSUM.EXE utility.
6. The following messages appear when the Memory Size Switch setting is too small for the
downloaded file.

2.3 TARGET FLASH MEMORY PROGRAMMING
Programming of t he target’s FLASH memory begins with typing “P” followed by the “Enter” key. The
green LED on the TFP2’s front panel blinks while the target FLAS H memory is being mass erased,
programmed and verified. The red LED will momentarily flash on at t he star t of pr ogr amming. Upon
completion of the target FLASH memory programming the following display appears. Additionall y , t he
green or red LED is illumi nated upon completion of the target F LASH mem ory progr amming.
Figure 2-10: T FP2 Target Mass Erase and Program Command
If the existing devic e’s securi ty bit is set, the TFP2 prompts for confirmation that programming is to
continue.
Figure 2-11: Existing Device’s Security Bit S et
Type an uppercase “Y” t o continue device programming.
Pressing the Program Button on the front panel of the TFP2 automati c ally proceeds with device
programming regar dless of the security bit setti ng.
Figure 2-12: Programming Overrides Security Bit
Revision 2.3 13 of 36
Page 14
Flash Programmer Model TFP2 User’ s M anu al
If the TFP2 cannot communic ate with the target board, a “Command Timeout” message appears.
Possible reasons for a Command Timeout indication upon programming the target board:
1. Power not provided to target board preventing TFP2 communication with target boar d.
2. Bad cable connecti ng TF P 2 to target boar d pr ev enting TFP2 communication with target board.
3. Malfuncti oning target board preventi ng TFP2 communication with target boar d.
4. TFP2 Programmers buil t bef or e J une 2011 m ay have timing issues with some 78M66xx devi c es.
Contact Teridian for further information.
NOTE: The TFP2 must be powered first before connecting the target board to the TFP2.
NOTE: The target’s watchdog timer must be enabled (V1 pin not connected to
V3P3) and the target’s I CE _E pin must be connect ed to the approp riate
TFP2 connector pin for target flash re-programming if the target’s secu rity
bit is set.
NOTE: Wrong Memory Size switch setting will result in a Verif ication Error FAIL message.
2.4 PREVIOUSLY PROGRAMMED DEVICE VERIFICATION
A previously programm ed dev ic e c an be c hec k ed against the cur r ently loaded image contai ned in the
TFP2. Use the “C” command to perform t his compar ison. The green LEDs are illuminated if the flash
contents of the dev ic e in the socket m atch the contents of the TFP2 EEPROMs.
Figure 2-13: Previously Programmed Devi ce Check
If the security bit is set, the target’s FLASH memory cannot be read. Therefore, the Compare result s will
fail as shown below. The red LEDs are ill umi nated indicating thi s condit ion.

2.5 DEVICE STATUS CHECK
The contents of a devic e may be read-bac k to display its current security bit setting and checksum. Use
the “T” command to perform t his read-back.
Figure 2-15: Device Checksum and Security Bit Status
If the security bit is set, the target’s FLASH memory cannot be read. Therefore, the Status results cannot
be displayed as shown below.
Figure 2-16: Device Checksum and Security Bit Status with Security Bit Set
2.6 CODE OR PARAMETER UPDATE
The TFP2 firmware typi c ally performs a block erase prior to programming the device’s flash memory.
Additionall y , t he TFP2 progr am s the entire address space of the flash m em ory. The “D” command all ows
for programming only a small portion of the target’s FLASH memor y, i.e. – code patch or parameters.
Use the “D” command to download a code patch or a parameter table to the TFP2 EEPROM without
erasing and reprogramming the entire TFP2 EEPROM memory. The memory loc ations to be
reprogrammed are read f r om the downloaded Hex File. F ollow the same instructions of Secti on 2.2
regarding select ing “Send Text File” menu option after typing the “D” command.
Use the “P” command or the PROGRAM button to program the target board’s FLASH m em ory wit h the
updated TFP2 EEPROM content s.
The TFP2 Power-Up checksum v erific ation expects to read the ori ginal Teridian checksum. The PowerUp checksum verification may fail due to the code change. A Power-Up Verify fail does not prevent
correct device m em ory progr amming (these messages are inf ormational only). Use the “T” command to
verify the current device checksum.
2.7 PARAMETER PRESERVATION PROGRAMMING
The TFP2 firmware typically performs a block erase prior to programming t he devi c e’s flash memory.
Additionall y , t he TFP2 progr am s the entire address space of the flash m em ory. Opti onally , the TFP2 can
reserve 4KB of flash memory for code or param eter tables.
Use the “E” command to toggle whether the 4KB is preserved or erased/over-written during the “P”
programming operation. The Parameter Mode status change is displ ay ed as shown below.
Revision 2.3 15 of 36
Page 16
Flash Programmer Model TFP2 User’ s M anu al
Figure 2-17: Paramet er M ode Selection
After setting the Par am eter Mode using the “E” command, programm ing can be initiated using the “P ”
command or by pressing the f r ont panel Program button.
When Parameter Mode preservation is enabled, the TFP2 progr am m ing operation copies the existing
parameter data f r om the target device. A bulk erase and reprogramming of t he target’s FLASH memory
is performed. The TFP2 then r estor es the pr ev iously copied parameter dat a star ting at its highest
address locati on. Parameter data is re-wri tten to decreasing address locations until all parameter data
locations have been r estor ed. If new code (non 0xFF data) is encountered ( above the lowest reserved
parameter address loc ation) the message “No parameters preserved” is displayed during the
programming operation.
The location of the 4KB par am eter space depends on the target device’s FLA S H m em ory siz e. The
TFP2 determines the tar get FLASH memory size from the front panel Mem or y Size switc h. The following
table shows the reserved address locations of param eter space for different m emory si z es.
Memory Size
Switch
8KB Not Used Not Used
16KB 0x2000 0x2FFF
32KB 0x5000 0x5FFF
64KB 0xD000 0xDFFF
128KB 0x0001:D000 0x0001:DFFF
256KB 0x0003:D000 0x0003:DFFF
Table 2-4: Parameter Space Address Locatio n
Usage of the above parameter space assumes new program code does not exist at the prev ious
parameter( s) address locations. The TFP2 also assumes that the param eters are stored as a contiguous
block. This block of paramet er s can be located anywhere within the reserved memory locations.
Locating the par am eters at the end of the Parameter Space allows for the progr am code to “ gr ow” i nto the
lower addresses of t he par am eter space.
The location of the conti guous parameter block is determi ned by searching for a non 0xFF data byte
beginning at the Par am eter Space “End Address” of the TFP2’s EEPROM im age. The address counter i s
decremented until a non 0xFF value is found. This locates the lowest address of the parameter data, the
“End Address” being the hi ghest addr es s.

The TFP2 Power-Up checksum v erific ation expects to read the ori ginal Teridian checksum. The PowerUp checksum verification may fail due to the code change. A Power-Up Verify fail does not pr event
correct device m em ory progr amming (these messages are inf ormational only). Use the “T” command to
verify the current device checksum. The “T” command always includes the Parameter Space addresses
in its checksum calculation regardless of the Parameter Preservation Mode setti ng. However, the “C”
command operation varies with the Parameter Preservation Mode setting. The Parameter Space

3 TARGET CODE INITIALIZATION
Before the target’s FLA S H m em ory can be pr ogr ammed, the target code must be transf er r ed to t he TFP2
for internal storage. First configure the TFP2 for the proper mem ory siz e of t he target’s code. Rotate the
internal Memor y Size r otary switc h to the appropriate position. There is a black arrow on top of the rotary
switch shaft denoting the switch position. Only six of the eight switch positions are used. The other two
positions are not used. A blink ing red LED after applying power to t he TFP2 indicates one of these
unused positions is curr ently selected. Rotat e the Mem or y Size S witch to a proper setting and re-apply
power to the TFP2 to update the Memor y Size setting.

4 TARGET FLASH MEMORY PROGRAMMING
The TFP2 Flash Programm er connects to the target board via one of two connect or s:
1) The Target-LS connector pr ov ides connection using discrete wires.
Only use this interf ac e for TCLK frequenc ies of 10 MHz or less.
Figure 4-1: Target-LS Connection
2) The Target-HS connector utilizes the ADM-1 ribbon cable connect or .
Must use this interface for TCLK frequencies of 10 MHz or faster.
Figure 4-2: Target-HS Connection
These two connectors are hard wired together. They are not two separate i nterfaces (two different target
boards cannot be programm ed c onc ur r ently).
The Target HS interface must be used when programming 73S12xxF and 78M66x x dev ic es
regardless of the TCLK speed.

programming, the t ar get’s FLASH Memory contents are read back for verifi c ation. The green
Programming/Pass LED stops bl inking and turns on solid if t he target’s FLASH Memory content s are
verified as good. If v erific ation fails, the red Fail LED turns on solid. If the TFP2 cannot communicat e
with the target, the red F ail LE D turns on immediately. Communicati ons failure may result from no target
power, bad cable or fault y target board. No target FLASH Memory programmi ng will hav e oc c ur r ed when
communicati on has not been established. Either LED indicati on is cleared upon re-pressing the Program
button.
NOTE: The TFP2 must be powered first before connecting the target board to the TFP2.
NOTE: The target’s watchdog timer must be enabled (V1 pin not connected to
V3P3) and the target’s I CE _E pin (if avai lable on target device) must be
connected to the appropriate TFP2 connector pin for target flash reprogramming if the targ et’s security bit is set.
4.2 PC USER INTERFACE PROGRAMMING
Alternatively, manual programming may be performed using the PC User Interfac e. The green and red
LED indicators func tion as described above. The operational status information is also duplicated on the
PC’s screen. Refer to Section 2 for instructions on using the PC User Interface.
Figure 4-6: PC User Int erf ace Con f ig uration (shown with Target-HS cable fo r exampl e)
NOTE: The TFP2 must be powered first before connecting the target board to the TFP2.
Do not connect a PC to the TFP2 AND connect the TFP2 to a target board with any connection
to Line or Neutral. Equi pm ent damage will occur due to a Ground signal disparity or live
voltages.
4.3 ATE FACTORY AUTOMATION PROGRAMMING
Automated programming of the target’s FLASH Memory may be performed using the ATE connector.
The interface si gnals provided at the ATE connector allow a fac tory automation computer t o commenc e
programming and monitor the status of the progr amming results. The ATE interface cannot download
target code to the TFP 2’s i nternal EEPROM.
The TFP2 must be powered fir st before connecting the target board to the TFP2.

5 BOOT LOADER
The TFP2 Boot Loader enables the TF P 2 firm ware to be upgr aded in the field (rem ote location). The
Teridian Semic onduc tor provided TFP2 firmware file is first downloaded to the TFP2’s EEPROM.
Transfer of this revised firmware file from the TFP2’s EEPRO M to its loc al pr ogr am m em ory is performed
by typing “BOOT” at the command pr om pt. Detailed Boot Loader instructi ons are prov ided in the
following secti on.
5.1 BOOT LOADER OPERATION
Reprogramming (upgr ading) of the TFP2’s program mem or y is accomplished with the following steps:
1. Set front panel Memory Size switch to 64 KB position.
2. Download the new TFP2 firmware file using the “H” command. Follow the instructions described
in Section 2.2.
3. Update the TFP2 program memory usi ng the “BOOT ” command. The “BOOT” characters must
be upper case.
Figure 5-1: TFP2 Reprogram TFP2 Program Memory
4. To proceed with reprogr amming the TFP2, type an upper case “Y”. The green PASS led blinks
during the reprogr amming process. The TFP2 restarts it self onc e r epr ogr amming is complete.

8 TROUBLESHOOTING
Proper function of t he TFP2 with the target IC depends on many factor s. These factors are:
• Cable length and cable quality
• S ignal termination
• Target board and target I C function
• M atch between selected flash program size and target flash size
When the programming pr oc ess seem s to f ail, it is useful to watch the feedback messages from the TFP2
via HyperTerminal. Using the C and/or T commands it can be determi ned quic kl y if t he issue is with t he
communicati on link or somewhere el se.
8.1 COMMUNICATION ERRORS
The typical response of the TFP2 to a communication error when issuing t he C c ommand looks as
follows:
>C
Comparing Target Flash to TFP2 EEPROM image
Command timeout.
Command timeout.
FAIL
>
The response to the T command will look as follows when the communication link is interrupted:
T
Command timeout.
>
Likely causes for c ommunication link issues are:
• Cable length – try to keep the cable length below 25 cm (10 inches)
• Cable quality – proper multiple grounding and strai ght cables without loops are preferred. Try to
use the original ribbon c able with an adapter to the target progr amming connector, if necessary.
• If the TFP2 and the PC connected to it have a different ground potential t han the target, ground
loops can occur. In that c ase, try to use an isol ated supply for the target.
• Termination – in-li ne r esi stor s, pull-up resistors (if used) and by pas s capacitors should be included in the target schematics in the same way as implemented on the Teri dian Demo Boards.
Consult the Demo Board schematics for comparison.
• Target board power – 3.3 VDC must be supplied to the target IC.
• Target oscill ator – ensure t hat the crystal is oscillating at 32. 768 k Hz using an osci lloscope. In
many cases, board contami nation or moisture can prevent the oscillator from functioning properly.
• ICE_E not pulled high – this pin, if available on the t ar get I C, must be pulled high.
• V 1 pin for 71M651x target ICs – for this IC family, the V1 pin must be pulled up to 3.3 VDC to dis-
able the internal watchdog timer.
• St uck RESET pin – the communication link will fail if this pin is tied to the active potential.
• S ome older TFP2 units may have timi ng issues when pr ogr am m ing 78M66xx devices. See Secti on 2.3.

8.2 VERIFICATION ERRORS
A typical dialog inv olv ing a verification error i s shown below. I n this case, the communication between
TFP2 and the target IC was establi shed, but the programmed target image had at least one error, which
was discovered duri ng the verify process.
>P

Verification error.
FAIL
>
Likely causes for v erification issues are:
• Communication issues can look like a verification error if the signal quality and timing is marginal
– check the items listed above under Communication Errors.
See the hints given in Section 8.3.
• A n em ulator port signal is also connect ed to an LCD pin on the target board resulting in a
corrupted signal – pr ov ide a jum per that c an isol ate the LCD pin from the emulator signal(s)
during the flash program m ing process.
• Mismatch between selected target flash size and actual target flash size – check the setting of the
Memory Size Selection Switch and compare the file size with t he flash size given in the target IC
data sheet. For example, the 71M6534 has a flash size of 128 KB whereas the 71M6534H has a
flash size of 256 KB.
• M ismatch between linked t ar get fi le size and actual target flash size – check the li nk er settings
and linker report files.
• File error – check the target file loaded into the TFP2. Reload the file, if necessary.
8.3 CABLE ISSUES AND MARGINAL TIMING
Cable issues and marginal timing can manifest them selves as intermittent communication errors and/or
verification errors. If the methods listed in the previous section Verific ation Errors do not help, a few unconventional fixes can be tried:
• Raising the board volt age to 3.6 VDC.
• A dding a resistor of 10 kΩ between E_RXTX and V3P3.
8.4 FILE LOAD ERRORS
File load errors can occ ur when att em pting to load the target image fil e into t he TFP2 using
HyperTerminal. USB-to-serial converters sometim es misinterpret the XON/XOFF control sequences used
for flow control. These cases manifest themselves in stuck file loads or corr upted target images. The
solution is to move to a PC with a true seri al interface (COM port).
