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

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.

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?
