FPGA Central

I have a 402 Virtex 4 board from Xilinx. I don't have one of the special
cables required to load it so I am trying to use the System Ace method and
adding my configuration as MyAce. I'll withhold my comments on why they
require a special cable but don't supply it with the board.

I seem to be able to generate a MyAce.ace file ok, but it is 1,674 KB long
and I get an error when I select it. I notice that all the other working
..ace files are 1,686 KB long, so I assume I am doing something wrong. Any
idea what or any recommendations? I wanted to order a cable kit but they
were out of stock. Any other sources?

Thanks in advance,

Marco

Hi Marc,

the SystemACE CF is not so bad, when it works, but trouble is easy to come

http://wiki.openchip.org/index.php/SystemACE

the different file size may be ok, as the .ACE contains the .BIT and
possible .ELF files
so the .BIT are some SVF are merged to create the mysterios secret .ACE file
format.
check that the FPGA startup clock is JTAG and that the JTAG chain
configuratian is ok.
hmm.. with some V4 boards I think there are special workarounds to "fix" the
ACE files
check the stuff that did come with the board if there are some batch files
or special
instructions.
On our V4 board (V4LX25 from Memec) the SystemACE did never works
and the board designer suggested that we return the board. I think the
problem
was related to V4LX25 ES JTAG errata.
but all ML40x boards work from systemACE so thats not your issue.

as of supplying the board without cable thats actually perfectly fine:
we have here at least 6 cables (3 different types) that coud be used
with ML40x boards, so shipping the board without cable is ok.
if xilinx is out of stock with Cable IV then

www.amontec.com
the reconfigurable dongle can be programmed to be Cable III and it
includes the 14 pin header and cable so you can use it with ML402
just ask that you need the xilinx adapter and cable when ordering
I am sure amontec can ship immediatly

antti
PS the trouble with cables and systemACE (or similar solutions)
is why
http://www.hydraxc.com
includes special processor that can configure from normal filesystem
using standard xilinx .BIT files, just copy the .Bit to the mini SD card
and insert the card. No cables. No conversion to some mysterious
format. Verbose error reporting in case of configuration failures.
Fail safe remote updates (by restoring last known configuration
if new update doesnt work).

I generated my_system_ace.ace file using iMPACT for my design .bi
file and I copied to the CF to configure the virtex4 FPGA on ML40
board. Bur I am getting error(Err led lights with red) when
selected my_system_ace.ace from the CF

any help pleas

thank
