Re: gEDA-user: User Controlled Technology Ogg Vorbis player
Take a look at gumstix (www.gumstix.com). It's not a kit in the manner that you describe, but they've got all the pieces you would need to construct your own player. --wpd ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

It did involve kernel module compilation. It sounds like Linux is all but unsupported still. Token efforts of supporting Linux by only supporting one configuration of one distribution is not, in my opinion, an honest approach to saying, We support Linux. I suppose I can give it a try, but with my past history with installing way-flakey software in the past, it sounds like it'd just plain be easier for me to go with Windows. Well, I've run the Xilinx tools on various incarnations of SuSE on AMD64 for a while now. The PC-IV driver doesn't work because it's a 32bit driver, but impact does otherwise function on my Linux. In fact, I don't think there is any version of Linux that it does *not* work with, so you should be fine. There are some answer records for various portability glitches. As for it being less flakey on Windows, well... it just ain't super-wonderfull-happy-as-a-mac software, Windows or Linux. It's former Unix software ported to Windows, and back again :-/ -- Steve WilliamsThe woods are lovely, dark and deep. steve at icarus.com But I have promises to keep, http://www.icarus.com and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: CPLDs and other high-density logic chips...
Samuel, I have worked with least two different options you might be able to use. First of all, I haven't tried this, but I believe that you can compile Xilinx FPGA's directly from Icarus, as this program apparently was done in cooperation with Xilinx. I have used Xilinx FPGA's, and I can recommend them highly, with the exception that the ones I have used are volatile and require a serial PROM to load them when the power is applied. As a second option, I have used Lattice devices as well, but I have not been able to program these from Icarus and have had to purchase ispLEVER to accomplish the programming. These units do have the advantage of being non-volatile, so that problem doesn't exist with Lattice. I have also (several years in the past) used Actel FPGA's. Again, they work well, are non-volatile, but would require their own compiler. Hope this helps. Harold Skank On Sat, 2006-09-02 at 22:30 -0700, Samuel A.

But I really have no knowledge of how to prototype with such beasts. Is there a body of resources that you folks would recommend to a *total* neophyte with respect to CPLDs and FPGAs? The farthest I've gotten in Verilog was to actually get something to simulate via Icarus, but actual synthesis and resynthesis is something that still escapes me, unfortunately. Also, what kind of capital investment am I looking at? My plan was to use a relatively simple CPLD for address decoding and other glue logic functions, but also perhaps an FPGA for generating VGA (640x480) video.

Re: gEDA-user: CPLDs and other high-density logic chips...
You can actually do without the binary only kernel modules. I use a GPL tool called xc3sprog to program my Xilinx fpga devices. Do a quick google and you'll find it. It only officially supports Spartan 3 devices but I was able to make it program a Virtex II Pro as well. Let me know if you need some help getting it set up. -David Carr Joshua Boyd wrote: On Mon, Sep 04, 2006 at 05:16:47PM -0400, Darrell Harmon wrote: The Xilinx software is available for a specific version of Redhat Enterprise Linux on x86 machines.
