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

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.

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"

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"

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

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

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 i

Virtex 4 FX12 for Ethernet application. Is there any reference desig available that uses only embedded MACs but not Gigabit MAC(I suppos that needs licence and given in ML403 reference design).

Thank in advanc

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:

And the updated design files can be found here:

Hi Ed

Thanks for ur info of that gsrd reference design is available fo

ml403. I have used it and run the treck tcp/IP stack.

For me more interesting is running a simple webserver applicatio

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 i

application notes 663 but how one can use the same for virtex 4 device on ml403. what kind of chages required to run the webserve application

please give me some hints or notes which help me to use the trimod

ethernet MAC.

Hi E

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.

Hi Ed

where do I find the webserver design source of "webserver using Har

Tri-Mode Ethernet MAC . ML403".

I tried to design it myself and got strucked with clock placemen

constraints errors in PAR.

Hope there must be some guidelines to run webserver applicatio

similar to the one in ML403 tutorials.

Can u please give some info or hints to use TEMAC in my design to ru

webserver application on ML403 board

thanks in advanc
