Free Spartan3 download program for GNU/Linux

I, like others, am a little upset by the lack of a free (ISE Webpack) 
version of impact for GNU/Linux.

As discussed in an earlier thread impact will not run under wine, it 
will not access the parallel port. However it can be made to produce SVF 
files.

Using information from XAPP188 I was able to configure the Xilinx 
Spartan3 Starter Kit (the FPGA, not the Flash yet).

I am not able to compare the speed with impact, but I can tell you that 
I configured a xc3s200 in about 4.3 seconds.

This software is at it's early stage of development and I have only 
tested it on the Xilinx Spartan3 Starter Kit. It doesn't need to run as 
root since it uses /dev/parport0. Oh, it doesn't need its own kernel 
module driver either, unlike some programs!

With ISE WebPack running on wine and now being able to configure the 
FPGA from GNU/Linux, do we have a complete tool chain for GNU/Linux that 
is free?

Hi

Tested and working on my board (Avnet kit). A small patch was needed :

Can you tell me if your program works also for Spartan2 FPGA's ?

Regards,

       Martin 

Already I have received a few bug reports, thanks Sylvain.

A new release, Release 0.3, can be found at

http://www.rogerstech.co.uk/XC3Sprog.tar.gz

I have included more Spartan3 devices in the device list.

I think the programming algorithm is different, but try it and let us 
know. I have included some XC2Sxxx definitions in the device list to 
make easier to try.

Unfortunately I only have the Xilinx Spartan3 Starter Kit and cannot 
verify its operation with other devices. Donations will be appreciated!

Thanks
Andrew

Not sure what you mean by "the FPGA, not the Flash yet".  Can you explain?
Does this imply that we can now use the $99 board that Xilinx is selling 
with Linux now?  What limitations are implied by "not the Flash yet"?

Good work!

The flash is the little PROM on board, the non-volatile memory. The FPGA need to reload its config each time it's powered. It can download it's config from a little flash on the board (so that the board is autonomous) and this PROM is on the JTAG chain too, but you can't program it with this application yet.


Personnaly, I'm now doing all my Xilinx work under Linux.

I use wine for the WebPack. That's sometimes a little slow when "compiling" but that's OK. And this prog to program the bitstream.
The only thing I can't do is program the PROM.

In due course I'll be working on programming the PROM. At the moment I'm 
struggling to find a datasheet on the XCF02S PROM that gives the 
programming algorithm. Even without the datasheet I will not give up.

Can anyone tell me where I can find the programming algorithm for the 
XCF02S PROM?

Thanks
Andrew

One would think that the "Complete data sheet for Platform Flash 
In-System Programmable Configuration PROMs" would have details on the 
"In-System Programmable" features. I think the marketing department has 
been at work here!

It does give:
Instruction register length.
IDCODE.
Instruction capture values.
JTAG signals timing.

It does not tell me about "In-System Programmable"!

"Complete" ?

I think its not published!
but that doesnt mean it cant be programmed.
just generated SVF and look what is done there :)
