JTAG-Booster for AMD ÉlanSC520
1. General
The program JTAGEL5 uses the JTAG port of the AMD ÉlanSC520 embedded
microprocessor in conjunction with the small JTAG-BOOSTER:
•
•
•
•
•
to program data into flash memory
to verify and read the contents of a flash memory
to make a memory dump
to access a I2C Device
to test CPU signals
All functions are done without any piece of software running in the target. No
firmware or BIOS must be written. Bootstrap software may be downloaded to
initially unprogrammed memories.
For latest documentation please refer to the file README.TXT on the distribution
disk.
1.1.System Requirements
To successfully run this tool the following requirements must be met:
•
MSDOS, WIN3.x, WIN9x or WinNT
(WinNT is supported with an additional support-kit)
•
Intel 80386 or higher
•
205 kByte of free DOS memory
•
no extended memory
•
Parallel Port

+3.3V
*PIN 2 can be detected by the white thick cable.
To connect your design to the JTAG-BOOSTER you need a single row berg
connector with a spacing of 2.54mm on your PCB. The names refer to the target:
Pin 7 is the target’s TDO pin and is connected to the JTAG-Booster’s TDI pin.
A 3.3V version of the JTAG-Booster is delivered for the AMD ElanSC520.
Do not connect the 3.3V JTAG-Booster to a 5V power supply. The JTAGBooster may be damaged.
Before you start the program, the JTAG-BOOSTER must be plugged to a parallel
interface of your PC and to the 8 pin JTAG connector on the target.

The utility is started with the general command line format:
JTAGEL5 /function [filename] [/option_1] ... [/option_n].
Note that the function must be the first argument followed (if needed) by the
filename.
If you want to cancel execution of JTAGEL5, press CTRL-Break-Key.
On any error the program aborts with an MSDOS error level of one.

The initialization file JTAGEL5.INI was found in the current directory.
(2)
The target identification line of the initialization file is printed here.
(3)
The resulting I/O-address of the parallel port is printed here.
(4)
A JTAG-Booster is found on the parallel port
(5)
The JTAG chain is analyzed. There may be several parts in the JTAG chain.
The chain is analyzed and all parts except the AMD ÉlanSC520 are
switched to bypass mode.
Please note: The current revision of the AMD ÉlanSC520 has a silicon bug
with the JTAG identification register. As a result of that bug, the contents of
the identification register is shifted out infinitely. If there are other devices in
the JTAG chain, the AMD ÉlanSC520 must be the first part in the chain
(nearest to TDI). Otherwise the JTAG-Booster does not work.
(6)
The length of all instruction registers in the JTAG chain are added.
(7)
The position of the AMD ÉlanSC520 in the JTAG chain is checked.
(8)
The position of the JTAG instruction register of the AMD ÉlanSC520 is
checked
(9)
One Flash-EPROM AMD 29F040 selected with chip select BOOTCS# is
found.
(10) In this example two blocks must be erased.

1.4.Trouble Shooting
Avoid long distances between your Host-PC and the target. If you are using
standard parallel extension cable, the JTAG-BOOSTER may not work. Don't use
Dongles between the parallel port and the JTAG-BOOSTER.
Switch off all special modes of your printer port (EPP, ECP, ...) in the BIOS
setup. Only standard parallel port (SPP) mode is allowed.
On very fast PCs there could be verify errors. To avoid this, watch for the
´IO recovery time´-switch in the BIOS Setup which must be turned on. Otherwise
try to slow down your PC by setting the turbo switch off.
When using older flash devices (nearly maximum erase cycles reached), we
propose to use the /VERIFY option. This is also true for the relatively slow 3 Volt
only flash devices.
Some newer fast flash devices need a setup time between address/data and the
write strobe signal. If programming of this devices fails, try with the option
/WRSETUP again.
If there are problems with autodetection of the flash devices use the /DEVICE=
option. To speed up autodetection specify the option /16BIT or /8BIT.
Don't use hardware protected flash memories.
The used chip selects must be defined as output and inactive in the initialization
file (see chapter 1.6 “Initialization file JTAGEL5.INI”). Also the address bits must
be defined as output.

1.6.Initialization file JTAGEL5.INI
This file is used to set the CPU signals for input/output. In case of output signal an
additional parameter is used to set the default level to high or low. This file can be
used to adapt your own AMD ÉlanSC520 design to the JTAG-BOOSTER. The
Target-Entry is used to identify your design which is displayed with most
commands.
When the JTAGEL5 software is started it scans the current directory for an
existing initialization file named JTAGEL5.INI. If no entry is found the default values
are used. You may also specify the initialization file with the option
/INI= . If the specified file isn't found, the program aborts with an error message.
The CPU pins can also be used with the functions /BLINK (chapter 2.9), /PIN?
(chapter 2.10) and /SAMPLE (chapter 2.11) to test the signals on your design.
Example of JTAGEL5.INI:

JTAG-Booster for AMD ÉlanSC520
The following options are valid for most functions:
/DRIVER=x with x = 1,2,3,4
A driver for the interface to the JTAG-BOOSTER on the parallel port may be
specified. /DRIVER=1 selects the fastest available driver, /DRIVER=4 selects the
slowest one. Use a slower driver if there are problems with JTAG-BOOSTER.
Default:
/DRIVER=3
/INI=file
An initialization file may be specified. By default the current directory is searched
for the file JTAGEL5.INI. If this file is not found and no initialization file is specified
in the command line, default initialization values are used (see also chapter 1.6
“Initialization file JTAGEL5.INI”).
Default:
/INI=JTAGEL5.INI
/LATTICE
For demonstration purposes this software works with the Lattice ispLSI-Adapter,
too. With the option /LATTICE you can simulate the speed achievable with the
simple ispLSI-Adapter.
/LPT1 /LPT2 /LPT3
A printer port may be specified where the JTAG-Booster resides.
Default:
/LPT1
/LPT-BASE
The physical I/O-Address of printer port may be specified instead of the logical
printer name.
/OUT=file_or_device
All screen outputs are redirected to the specified file or device. Note that you can't
redirect to the same parallel port where the JTAG-Booster resides.
Default:
/OUT=CON

2.1.Programming a Flash Device
Usage:
JTAGEL5 /P filename [optionlist]
The specified file is programmed into the flash memory. Finally a complete verify
is done, if the option /VERIFY is omitted. If the verify fails, the contents of the flash
memory is written to a file with the extension DMP.
The type of the flash device is normally detected by the software. When
autodetect fails you should use the /DEVICE= option to set the right flash device.
The known devices are shown in chapter 1.7 “Supported flash devices”.
Options:
/DEVICE=devicename
The device is detected automatically by switching to autoselect mode. In case of
trouble you should select the device by using this parameter to avoid
autodetection.
/NOMAN
If you use a flash device which is identical to one of the supported parts, but is
from a different manufacturer, with this option you can suppress the comparison
of the manufacturer identification code. We recommend to use this option
together with the /DEVICE= option to avoid failures in autodetection.
/DEVICE-BASE=hhhhhh1
By default a device start address of 3000000h (=48MByte) is used for accesses
to the flash device.
Default:
/DEVICE-BASE=3000000
Abbreviation:
/DB=
/OFFSET=hhhhhh
The programming starts at an offset of hhhhhh relative to the start address of the
flash device. If the offset is negative, the offset specifies an address relative to the
end of the flash device. See also option /TOP
Default:
/OFFSET=0
Abbreviation:
/O=
1
hhhhhh=number base is hex
30
JTAGEL5d.doc
JTAG-Booster for AMD ÉlanSC520
/TOP
If the option /TOP is used the option /OFFSET= specifies the address where the
programming ends (plus one) instead of the starting address. This option is very
important for Intel CPU architectures, because target execution always starts at
the top of the address space.
/FILE-OFFSET=hhhhhh
If FILE-OFFSET is specified, the first hhhhhh bytes of the file are skipped and not
programmed to target.
Default:
/FILE-OFFSET=0
Abbreviation:
/FO=
/LENGTH=hhhhhh
The number of programmed bytes may be limited to LENGTH. If no LENGTH is
specified the whole file is programmed.
Default:
/LENGTH=4000000 (64 MByte)
Abbreviation:
/L=
/VERIFY
If this option is specified, the result is verified on a cell by cell (cell=8bit or 16bit)
basis instead of a complete verify after programming. If you want both a cell by
cell verify and a complete verify after programming, please use a additional
command line with the verify function. See chapter 2.3 “Verify a Flash Device with
file”.
/NODUMP
In case of a verify error the contents of the flash memory is written to a file with
the extension .DMP. With /NODUMP you can suppress this feature.
/ERASEALL
Erase the whole flash device. If this option isn't set, only those blocks are erased
where new data should be written to.
/NOERASE
This option prevents the flash device from being erased.
JTAGEL5d.doc
31
JTAG-Booster for AMD ÉlanSC520
/BOOTCS /ROMCS1 /ROMCS2
This options may be used to specify one or more chip select signals to the flash
memory. The used chip selects must be defined as output and inactive in the
initialization file. (See chapter 1.6 “Initialization file JTAGEL5.INI”.)
Default:
/BOOTCS
/NOCS
Use this option to switch off all chip select signals. This may be necessary if the
device's chip select is generated via a normal decoder instead of using the AMD
ÉlanSC520 chip select unit.
/8BIT /16BIT
Specifies the bus interface to the target device. You can speed up autodetection,
if you specify the correct bus interface width.
/32L /32H
The JTAG-Booster is not able to handle the interface to a dual 16bit ROM (32bitROM). With this two options you can select one 16 bit half of a 32bit-ROM. The
option /32L selects the low word and /32H selects the high word. 32 bit flash
eproms are always connected to the SDRAM data bus. It is not necessary to
specify the option /MBUS if the option /32L or /32H is used. Do not specify the
option /8BIT together with /32L or /32H.
/MBUS
With this option the SDRAM data bus (MDx bus) is used instead of the general
purpose data bus (GPDx bus) for accesses to flash eproms.
/WRSETUP
By default write cycles to the Flash EPROM start with address, data and write
strobe set at the same time. With the option /WRSETUP you can force the
program to generate a setup time for address and data with respect to the write
strobe.

3. Implementation Information
This chapter summarizes some information about the implementation of the
JTAG-Booster and describes some restrictions.
•
The JTAG-Booster currently uses the EXTEST function of the JTAG-Interface
to perform Flash programming. The new debug interface of the AMD
ÉlanSC520 is not used.
•
The revision A0 and A1 of the AMD ÉlanSC520 have a silicon bug with the
JTAG identification register. As a result of that bug, the contents of the
identification register is shifted out infinitely. If there are other devices in the
JTAG chain, the AMD ÉlanSC520 must be the first part in the chain (nearest
to targets TDI). Otherwise the JTAG-Booster does not work.
