Wine does not support USB at all, and probably will not. A programmer connected by something other than USB is IMO a lot less useful. Mark made UrJTAG work with the LFXP10e in January. http://www.mail-archive.com/[email protected]/msg00055.html Of course programming doesn't really require the Lattice cable if a software other than ispLEVER or Diamond can be used. UrJTAG supports a bunch of different JTAG cables, some if not all being very affordable. You could look for FT2232-based ones, there are Altera USB-Blaster clones (both original and clones FT2232-based) for $30 or less, new on eBay. I would go with that. I have good experience from this particular seller: http://cgi.ebay.com/Altera-FPGA-CPLD-USB-Blaster-programmer-JTAG-cable-/280546985105 I have no experience from this other seller, and from photos it looks like the design uses a generic USB chip and emulates FT2232 behavior. It might or might not work, but it's cute and almost too cheap not to order just for fun: http://cgi.ebay.com/Mini-Altera-FPGA-CPLD-USB-Blaster-programmer-JTAG-/320576596300 David Hilvert wrote: > http://wiki.opengraphics.org/tiki-index.php?page=OGD1 indicates that at > least one free webpack supports 3S4000.

Updating, ie. getting a bitstream onto the board, only requires that cheap JTAG cable and UrJTAG to support the 3S4000. ISE is needed for making any changes to the design. Ah these little things like support tools.. I think it would be a good idea to approach Xilinx, but make sure to find the right entry point. Ideally they would donate full ISE licenses to the OGD1 community. Second best would be that deep discount. Worst case maybe they can donate one license to be shared in the community, via SSH. Upload source code, it runs synthesis, get bitstream and/or reports back. Sucks to need to be online to do development, but would still be better than nothing. The OGD1 is really useless for development without synthesis. //Peter _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
