xilinx virtex 4 download cable

Hi i have buy,

virtex 4 evalutation board. In the box there isn't any cable for the 
bitstream download.

Can i download with impact the fpga bitstream with serial null modem cable 
or usb cable?

In order to keep costs down and since most users already have a
download/programming cable we don't ship them with our boards.
We do disclose this on our ML40x product pages http://www.xilinx.com/ml401

You can not program through a serial null modem or a generic USB
cable.  You will need to buy a parallel cable (PC-4) or the new
Platform USB cable.

One other alternative if you have the ML40x board that includes
the System ACE controller and a compact flash card you can
create a new ACE file and write it, in the appropriate place, to
the compact flash card using your PC.

p.s.  Why are you using a fake email address that points to a
Xilinx address?  Most people just insert a nospam add on to slow
down the spam.

I only have the parallel III cable. Can I use it to download the bitstream to ML401?

I have parallel III cable and I tried to connect to JTAG interfac
port on ML403 board but I found it difficult to connect because o
insufficient spacing between pins

any help please.

The ML401, ML402, ML403 boards were designed with the new
ribbon connector style used with the PC-4 and USB cables.

The older PC-3 cables can not directly plug in to this
connector and I'm sorry, but we don't sell a conversion
cable either.

hi Ed

I found I/O expansion header port with JTAG pins. Can I use it for m
JTAG PC-3 cable instead of having PC-4. If so how can I do that an
what kind of jumper settings I have to do on my ML403 board

Even I am trying to use compact flash but I found some problem i
converting .bit file to.ace file. I used iMPACT to convert the fil
format but when I want to configure the device with the new .ace fil
the Err led lights on with red. What could be the problem

Please do u suggest me the best way to configure the device on ML40
board

No, that is for downstream use for configure a device on a
daughter card.  If you tried to use this you would have
contention on the TDI, TCK and TMS pins from System ACE.

You have to go in through the 1mm PC-4 header.

Hi Ed

I don't have parallel 4 cable instead using compact flash to configur
the device on ml403 board.  here I want to generate system ACE file i
EDK. Is that possible to generate ACE file without connecting to th
board with JTAG cable. Can u tell me what r the changes I must do i
genace.tcl script for ml403 board

Even I read "System Initialisation and Download" chapter 11 in ED
documentation and I tried myself to make some changes in xmd option
but I was not successful

Hope u will give some good hint.

There is no need to connect a PC-4 cable to the ML403 to create
a System ACE file.  I went back and looked at some of your previous
posts and it's not clear which software version you are using and
exactly what steps you have taken.  I would suggest that you initially
follow the steps on page 26 of the "ML40x Getting Started Tutorial"
http://www.xilinx.com/bvdocs/userguides/ug083.pdf

There are several reasons why your ACE file doesn't work. These
are prioritized in the order that I think is likely.

1) You didn't include everything in the JTAG chain when you
    created the ACE file in iMPACT. See page 33 of the "ML40x User Guide"
    http://www.xilinx.com/bvdocs/userguides/ug080.pdf

2) The file name or directory that you selected was not in the 8.3 format
    I know that this is old, but System ACE only has a tiny microcontroller
    in it and we created this device back in 6 years ago.

3) You forgot to update to xilinx.sys file to point to the correct
    dir location of the new ACE file.

4) The format of the CF card is not compatible with System ACE.

hi Ed

 thanks for ur reply
i went around and solved the problem of generating .ace file using th
steps explained in ml40x getting started tutorial

but now i stucked with generating system ACE file using the option i
EDK..tools..Generate system ACE. here I found a genace.tcl script an
tried to get .ace file simply clicking on Generate system ACE fil
option in EDK
but i was not that lucky to get .ace file instead getting some erro
messages.
when I looked into the genace.tcl script, found that needs to b
changed for proper xmd flow

here can u tell me what r the changes need to be done in genace.tc
script

thanks in advance.
if its not possible i can take .bit file and use the steps explaine
in the ml40x tutorial guide to get my .ace file, this now i becam
failiar and using right now

thanks for ur hel
