Xilinx Impact in Linux 2.6.x

Have anyone got Impact working in Fedora Core 3? Or any similar Linux?

I have tried this:

http://www.fpga-faq.org/FAQ_Pages/0044_Xilinx_Parallel_on_Linux.htm

but I probably get 1000 compile errors.

Is there any other possibilities for programming xilinx FPGA's?
I have read about NAXJP but can't find any places to download it,
I have tried http://www.nahitech.com/nahitafu/naxjp/naxjp-j.html#down
but can't find any links to click on to download it. I'm using a spartan
2E at the moment.

Why don't just Xilinx program against the parallelport in user-space
(ppdev) Instead of having two drivers??

I have an old RH8 based machine which I have connected to my device
under development in the lab. I run impact in batch mode (even from
home). This was an old celeron which I saved from the recycling bin.

I've made a prototype for an Ethernet-based programmer. I simply
upload my embedded programming file using tftp hence no device driver
is required, only a tftp client. Keep an eye www.etherblaster.com for
progress information (I'm doing this on my spare time so I'm moving
slowly).

Try
http://www.rogerstech.force9.co.uk/xc3sprog/

XC2S should work too.

Or if Xilinx would publish an interface to adapt one's own Jtag interfaces...

Check out XAPP058. It describes how to program the FPGA with a
microcontroller.  Should be simple to create a program to do this via
the parallel port.  There is a schematic for the cable on the Xilinx
web site.

I have not used the method in XAPP058, but have loaded a Spartan 3 by
using slave serial and a microcontroller.  It really works well.  It is
convenient too since the microcontroller has ethernet.

Does the Platform USB cable help? $149 ;-(

Holy cow.

Exact same price as the "coming soon" Spartan 3E starter kit, which also 
has an FPGA (xc3s500e), 32MB of DDR SDRAM, flash, Ethernet PHY, USB 2.0 
(Cypress EZ-USB FX2 I hope), etc.  I'm assuming it will come with Impact 
drivers to use the FX2 to drive the JTAG chain, and/or use serial slave 
mode, and hopefully an appnote on writing your own download sequence 
into your FX2 firmware.  Then again the Xilinx page lists the good old 
parallel JTAG cable as coming with it.  Just as long as they hook up 
enough pins to let the USB controller config the FPGA, I'll be happy.

Erik, where are the links for this starter kit please.

I thought it did not work on Linux, specially on my
non supported FC3 platform ....

No that did not work, it does read IDCODES form the system and does
have some XC2S devices in it's device list but it seems as the program
does not suppurt them. As can be seen from these lines in the source
code:

   if(strncmp("XC3S",dd,4)==0) programXC3S(jtag,io,file);
   else if(strncmp("XCF",dd,3)==0) programXCF(jtag,io,file);
   else{
     fprintf(stderr,"Sorry, cannot program '%s', a later release may be 
able to.\n",dd);
     return;
   }

Ahh I actually got it working, I just added:

else if(strncmp("XC2S",dd,4)==0) programXC3S(jtag,io,file);

after the line:

if(strncmp("XC3S",dd,4)==0) programXC3S(jtag,io,file);

And now it seems to work. I also added the device ID for my
XC2S100E and 18V01 to the the devlist.txt file.

Thanks for the tip about this program!

This is good now I just need one OS and one computer and no WMvare.
