NO

you need a JTAG cable to program the CPLD
then you can download the FPGA
much same idea as the ondemand thing

there is no "bootstrap" option that would
allow the board to be flashd with empty
CPLD and flash soldered === BAD design

Yes, there are vendors who do not make all of their design files
available for FPGA development boards. But for the most part, the
FPGA makers provide development boards and make all of their design
files available. I think they do this to reduce the amount of support
required. If you have all of the design files, you don't need to ask
so many questions, you can just look it up yourself. So in that
sense, there are a number of open source FPGA development boards.
Just not with the freedom to make your own copies although I can't
imagine an FPGA vendor would object since you would be putting their
parts on it!

No one can have a board manufactured for $6. You might be able to get
100 for $600 or possibly even 10 for $60, but not 1 for $6. That is
one of the problems with open source hardware. It is "hard" and often
difficult to make on your own. But that does not need to be a
problem. The most successful open source hardware (OSH) project I
have seen is the Beagle Board which can only be made in pretty
advanced factories. It uses a Package on Package mounting technique
for the processor memory as the OMAP CPU used is intended for use in
PDAs and cell phone like applications. So clearly, the fact that you
might have to sell some part or even all of the board would not doom
the project as Antti might think. (Not trying to put words in your
mouth Antti, just making a point).

In fact, I am thinking about an open source GPS receiver project which
would require not only the electronic hardware, but also a mechanical
design be done. Now *that* can be a problem for open source I
think.

Have you defined your goals for this project? If you are going to
succeed, you need to know what you are trying to do, *clearly*.
Others can give feedback on the goals and you can modify them to
include as many others as possible. Then you will get as much support
as possible.

Rick,

beagle is:
1) backed up by TI
2) uses (used) newest components

Cy's design:
1) uses OBSOLETED and NFND components

see the difference?

Cy: doing something different is an option

And as before i am failing to see what you expect to find?

I can only sayd that no "open source" developer will be
ordering and assembling those boards for personal use
and no company is interested to produce them either

so if somebody makes the boards its only you, and then
you have boards with 2 generation too old FPGA that
nobody is interested in, and that you can not sell even
for break even

Antti,

You have it all figured dont ya, Nobody, nothing, no company, no
interest. Well, seems as if two others have joined in to express some
interest.

I agree the mating components, 4 connectors, used on the board for
stacking the boards are expensive and therefore need to rethink
that.

There is an SPI flash in the lower right hand of that picture, which I
have used to boot load, yes it was programmed with the Xilinx platform
Cable USB II and the impact software. I do believe that the hardware
is in place to allow a file to be copied into the flash through the
USB, CPLD, FPGA. Add power from a walwart and the FPGA is up and
running. I am not all together convinced that this can not become a
multiboot system, however it is not spoken about in either XAPP951 or
XAPP974.

Rick,

I did not see the problem for your electrical and mechanical designs
of the GPS receiver. When the design is done and all is working
clients merely order the mechanical component order the electrical
component put it together. If there is need for something different
all design file are available for the next design, who ever it may be.
Clear goals: Yes, agreed. I have met my initial goals: an operable usb
powered and programmable fpga with a couple of addition for usability.
Now what? Well as antti has so strongly points out no one wants this
thing. Well, i have it, I am in need of it, and I do not want to
purchase any of antti products, or anyone elses, for any of my
contracted work, not that I have alot. I need some help in putting
together something a bit more robust and engineering friendly,
friendly to me and future work. I do not want to put something
together that does everything just gets far enough along that I can
work on the customers specifics. I can not be the only one in this
situation, therefore I want to work with a group of like minded
engineers to establish a good off the shelf component for future use.
Now, I'm not selfish I would like to share and make all of it
available, I like what happened to audrino it is a nice little 16 bit
processor. FPGA's do not suffer this identity crisis, 8 bit 32 bit
processors or whatever the hardware can be reconfigured to be. I need
it and want it. This board is only to say that I have the ability is
anyone else interested, well, the internet is good enough to house a
loose collection of engineers for a small project.

Nico,
What yet needs to be done, that's easy just look over Antti posts and
wherever he says no, not, cant, doesnt, neight just solve those
problems. Just because antti says no, not, cant, doesnt, neight does
not make it so.

Anyways- thanks for taking time to post and give me some ideas.

there is no failsafe multiboot in S3E

just another reason never use something as old as S3E

Antti
PS I am not as negative just trying to help you,
and yes i have pretty much figured out
