No clock to the FPGA? And no platform flash to configure the FPGA (or are you planning on the PIC to do that)?? and no JTAG to debug the FPGA?

Why not use a CPLD rather than FPGA? Don't have to load those so it would be up and running right away.

No clock needed for what I'm going to do. Although I still have the capability for a 32MHz clock through a control pin (PIC) if I ever need one. I have the PIC handling all loading on power up, and my intent is to have the bitstreams stored on the microsd card so they can be upgraded or changed as necessary. I may decide to simplify the design once I have it working - this is a prototype board, after all.

The PIC can do JTAG if I need it to, but I'm planning on doing the majority of my debugging using a test bench.

Looks nice, we're all hoping for an affordable price and no need for updates. ;-)

The cost to make this board fully assembled was about $60, FWIW.

What does FWIW mean?
For what I want(ed)?
For what it's worth?

I'd be prepared to pay that, plus margin, plus shipping, assuming it come in a box with all the essentials like the flashboy did.

Hopefully lack of donor parts will keep costs down.

I'm guessing over $100, which is OK for me, if they're cheap we can buy more... ;-)

FWIW = for what it's worth. I don't know about final costs yet, I was just saying it won't be any cheaper than that because if I sell these I want to make sure I'm at least not losing money. If I have to solder each board by hand that's probably 1-2 hours per board manual labor as well. But I'm not sure about any of that yet, I don't want to get ahead of myself.

Making 50 of these or so should get you some discount on parts at least. But see if you can get everything working and we can bother about cost reductions after that.

Either you'll go through all the troubles with casing, labels etc or just sell it cheap as a bare board and leave it to others to do the rest. There are some creative people here that usually take care of such things. ;-)

I'd love to buy one when they are ready or even get in on some kind of preorder when your closer to ready if you do something like that. Sounds sweet. Keep us posted.
