Xilinx LPT JTAG Cable

[cassinni]

Hi,

when I preordered my Xilinx LPT JTAG Cable there were no product images or notice it needs a LPT port.
Now I have no LPT ports
I read that I cannot use a USB-to-LPT adapter or a LPT PCI card to have a working LPT port, is that true?
Some say you cannot others say you can so I am confused..
I want to use this jtag cable to update my xecuter coolrunner.


thanks

You can NOT use a usb to lpt adapter
You CAN use a pci to lpt adapter (you need to tweak some settings in iMPACT)

I'm sorry - but this >

did the bit in red not give it away when you preordered???

iMPACT uses Jungo Windriver for communicating with usb and lpt, but it doesn't support PCI/LPT cards that uses legacy drivers.

You have to find your cards I/O range


Here is the solution:

Suppose your PCI/LPT card has a I/O range of D030 - D037

Modify settings32.bat (located in Xilinx/LabTools directory) by inserting 2 extra lines:

SET XIL_IMPACT_ENV_LPT_BASE_ADDRESS=D030
SET XIL_IMPACT_ENV_LPT_ECP_ADDRESS=D037

so it now looks like this:

"
@echo off
REM Copyright (c) 1995-2011 Xilinx, Inc. All rights reserved.

SET XIL_IMPACT_ENV_LPT_BASE_ADDRESS=D030
SET XIL_IMPACT_ENV_LPT_ECP_ADDRESS=D037

REM Set current working directory
set XIL_SCRIPT_LOC=%~dp0
REM Remove trailing slash
set XIL_SCRIPT_LOC=%XIL_SCRIPT_LOC:~0,-1%
REM Call settings file for each product
for /D %%d in (%XIL_SCRIPT_LOC%\*) do (
if EXIST %%d\.settings32.bat (
call %%d\.settings32.bat
)
)
REM Unset XIL_SCRIPT_LOC
set XIL_SCRIPT_LOC=
REM Execute command if any
if "%1" neq "" (
if /i "%~x1" == ".bat" (
call %*
) else (
start %*
)
)

"

Thats it. Should work:smile:

Thanks for your input.

1. How do you find out your PCI LPT Cards I/O range?

2. What do you mean with legacy drivers?

3. Does this work with any PCI LPT card?

1) Find your card under Device Manager and double click. Just use the top I/O range.

2) It means that the system simply translate pci address to LPT1, LP2... etc. Fine for connecting a printer fx but not iMPACT

3) The more advanced (and expensive) PCI LPT card functions as a prober LPT port and doesn't need this fix. The trick is that you can buy a cheep card and make it work. I did

You can NOT use a usb to lpt adapter

Why not?

 

[LED-Jtagz]

Why not?

USB to LPT adapters do not generally work as they do not contain the proper stuff to make them work. When I first got into the flashing scene I didnt want to spend the $60 for the x360usb pro so I bought a little $20 sata to USB converter, and guess what happened? It didnt work. Same with LPT to USB converters, not designed to work with everything, and they generally dont.

I know that USB ports doesn't use I/O range settings, but USB ports are hooked up to USB Host Controllers and those controllers do use I/O range.

So maybe it would just be a matter of finding the corresponding host controllers I/O range that a particular port is connected to.

hahahaha.....OMG , this is soo funny i actually spat my tea out ...hahah ...MY XILINX LPT DIDNT MENTION I NEEDED AN LPT PORT ....hahahahah how hillarious is that ...hahaha

 

[ArsenalFC]

i didnt know what lpt stands for when i preordered it. even my 2004 canon printer uses usb2.
i still dont understand why in hell they would use that
and not at least (!!!) usb2, but makes me happy u had a laugh greetings haha

 

[sdeens]

I can see his point, his generation did not know yet that LPT also means parallel or printer port, because that ancient hardware has minimal use moving forward.

I thought the question was reasonable.

btw:

The real question that has not been asked, is which is the best LPT port setting for PCI based cards?

I suggest next time you try ECP next time instead of the default SPP setting in your BIOS and watch what happens...it will flash and verify better, especially with homebrew cables.
