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.

Ed

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?

Hi

I have parallel III cable and I tried to connect to JTAG interface port on ML403 board but I found it difficult to connect because of 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 my JTAG PC-3 cable instead of having PC-4. If so how can I do that and 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 in converting .bit file to.ace file. I used iMPACT to convert the file format but when I want to configure the device with the new .ace file 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 ML403 board.

regards

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 configure the device on ml403 board. here I want to generate system ACE file in EDK. Is that possible to generate ACE file without connecting to the board with JTAG cable. Can u tell me what r the changes I must do in genace.tcl script for ml403 board.

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

Hope u will give some good hint..

regards

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 the steps explained in ml40x getting started tutorial.

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

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

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

thanks for ur help

regards

Since, you still haven't mention which version of the tools you are
using it's very hard for me to help. It's very lucky that you are
running into the issue described in answer record 21220
http://www.xilinx.com/xlnx/xil_ans_display.jsp?getPagePath=21220

If this doesn't help, please use the Webcase portion of our web
site to submit your problem and they will get back to you promptly.

These boards were developed by my team so I'm very familiar with them,
the reference designs and the documentation that we ship with them, but
I'm not an expert on the EDK tools.

Hi Ed,

Could u please tell me how o use tri-mode-ethernet MACs embedded in Virtex 4 FX12 for Ethernet application. Is there any reference design available that uses only embedded MACs but not Gigabit MAC(I suppose that needs licence and given in ML403 reference design).

Thank in advance

with regards

Good news we just updated the Gigabit System Reference Design (GSRD)
with the hard Tri-mode EMAC (TEMAC) cores and this runs on the ML403.
There is no license required to use the hard TEMAC and it will work
fine if just need 10/100 or if you just need 1 Gig.

More information can be found here:
http://www.xilinx.com/gsrd

And the updated design files can be found here:
http://www.xilinx.com/esp/wired/optical/xlnx_net/gsrd_download.htm

Hi Ed,

Thanks for ur info of that gsrd reference design is available for ml403. I have used it and run the treck tcp/IP stack.

For me more interesting is running a simple webserver application using powerpc.

Can you tell me how can I start implementing it on ml403 board.

I have seen one webserver application using lwIP for virtex2pro in application notes 663 but how one can use the same for virtex 4 device on ml403. what kind of chages required to run the webserver application.

please give me some hints or notes which help me to use the trimode ethernet MAC..

with regards
Rajesh

Hi Ed

I found echoserver application in EDK examples..
hope that will help me some extend to use the TMAC..

I come to u if I get any problems..
