Free Spartan3 download program for GNU/Linux

Hi

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

• unsigned char data=0x10; if(tdi)data|=1; // D0 pin2 if(tms)data|=4; // D2 pin4 ioctl(fd, PPWDATA, &data);

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

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

A new release, Release 0.3, can be found at

I have included more Spartan3 devices in the device list.

Regards Andrew

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!

Hi

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.

Sylvain

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 :)

I'm not sure if the links contain the information that you're after, but it may be a start. The 18V00 family is not the same as Platform Flash, but the general approach is similar.

Ok, so in otherwords its merely an inconvenience, not a show stopper.

good to hear. Up till now I was hesitant to buy the Spartan3 starter kit (the $99 board) because I didn't want to waste my money on something that would just sit around because I couldn't get it working under Linux. Now I'm probably goint to order it in the next few days. Thanks for your work on this!

Isn't there a free Linux version of the WebPack that only lacks the Impact programming tool? (maybe not, as I recall someone said that Xilinx used to the MainWin tool to port to Linux and MainWin requires a per/seat license).

Is there a particular version of Wine that you're running the Xilinx tools under? Any special tweaks to know about?
