Hello,
I am trying it on the Spartan-3 board of NuHorizon.
This board has, next to the spartan-3chip, a configuration device in the Jtag-chain
so you have to put that one in BYPASS mode, with an 8-bit command.
The ljp.c program doesn't work, firstly because it is for Virtex that have
5 bit jtag-commands, while the spartan-3 has 6 bit commands, as described in
the BSDL-file.
But alas after changing this, the ID-codes can be read properly, and bypass does also
work. But programming doesnt:(. Both chip's are revision 0 by the way.
The spartan-3 datasheet (part 3: page 38, figure 24) describes some details of how to
program it. But that doesnt help me any further.
As an aside, I make the bitfile with the option "-g StartUpClk:JtagClk" as is mentioned
by the Impact program and in the documentation.
The question is, does the spartan-3 specify the programming in it's datasheet, or is
there some vital part of the specifation missing from the datasheet.
The ljp program follows this, and I tried a lot of variants, also looking in xapp139.pdf about
virtex programming.
If the datasheet is telling the full story it should be fairly trivial to make it work, so I
am afraid I'm missing something, but what?
cheers,
Sietse Achterop
PS. I also tried my luck with the "mitoujtag" program, but I can't get the giveio.sys to function
under wine. Does anyone know how to do this?

Has anyone tried this program with the $99 Xilinx eval board?

But could the windows version using wine be used here?
Can the linuxdrivers be used of are they only for the native Linux version of ISE?
I recently bought a Spartan-3 board from NuHorizons in the hope to use
it using WebPACK under wine on Linux.

Ooops. I forgot. Xilinx does not release a LInux version of WebPACK.
Nix that previous message.

If you just want to download, you can use the free WebPACK version of
iMPACT. This would include the latest software and be backward
compatible with bitstreams generated from any version of ISE ou have.
So you are not actually stuck.

Did some testing, there is no module named ppdev.
panteltje:~# lsmod | grep p
parport_pc 14192 1 (autoclean)
lp 6592 0 (autoclean)
parport 24992 1 (autoclean) [parport_pc lp]
Removing and insmodding any of these does make no difference, except now I get:
open parport: No such device
Of cause I have /dev/parport0 etc...
Maybe I should not be using /dev/parport?

Do you have the ppdev kernel module loaded? If no, do it. If yes, do you
have any other device claiming the papalle port loaded (e.g. a parallel
port CDROM or such). If yes, unload. Try again.

I have taken that source, added a makefile, and added a way to add the
bit filename in the command line, also added some error checking.

I get:
claim parport: Invalid argument
I am using kernel 2.4.25.
Any ideas? This comes from:
if (ioctl(d, PPCLAIM)) err(-1, "claim parport");
Nevertheless interesting code.

I am not sure how relevant this is, but there is some source code
and other notes in the FAQ: "Downloading a Bitstream under Linux"
