Congratulations!
Thanks for your great work! looking forward to see the video
We've got a working system with a single, fully-populated hash unit (1 condo unit)!
Big, big thanks to SebastianJu for sending me a total of 11 chips.
Huge thanks to my collaborators in Ohio. They will be making an announcement soon.
I will take a video of my setup later, and show it on this thread.

I will be silent (no news) for about a week. I am moving to Washington state, and am waiting for the next prototype run.
I just went through the schematic and could not find any thing connected.
Maybe its for debugging the internals of the FPGA it looks like a differential clock ,reset and something else.

No, P2 is not being used at all. Avalon has just updated their pictures: https://bitcointalksearch.org/topic/m.2488633
Now it's showing Version 1.5 of the card.
I have great news! The Control Unit works now. If I load the bitstream directly to the Spartan chip using JTAG, it works; however, when it's loaded from the Flash chip, it doesn't run. One of my collaborators has suggested that may be it's because, as indicated in the reference documents, some parts of the bitstream are licensed cores and cannot be made part of the bitstream. So the file that gets copied to the Flash chip is missing those licensed cores, but programming the Spartan chip directly allows the iMPACT programmer to load the licensed cores from its library. If this is the case, no problem. We will buy the license to those cores. This kind of thing is already included in my calculations for the price of each condo unit.
Have you been able to look at the configuration signals with your logic analyzer?
No, I still don't know what the P2 header is for. Any ideas? I am posting a question on the Avalon support thread.

USB on Control Unit works! But there are other remaining problems. Getting there ...
Great work! Thanks for sharing the video.Have you been able to look at the configuration signals with your logic analyzer?
+1
really great work here!
I would also jump on your boat because it looks really promising but unfortunatly I have no chips left from group buys (I send a few to burnin and the other to K16 manufacturer).
Keep up your work!

Been too busy working on the Control Unit and Condo Management System, I haven't had time to update. For now I am just posting here a video about the state of the Control Unit. So far I am able to write the bitstream onto the Flash PROM, and the Spartan-6 is loading the bitstream during startup.

Cross-post in all threads of projects that are registered for Avalon sample chips from my order.
Delivery of sample chips seems to have started.
If you have chips ordered with me that you want to support this project with, do it now.
If you are the owner of this project, please provide me your shipping address.
Find the details here.

It looks like we are the first to get a Control Unit working. This is an important step in building an Avalon system clone. Is there anybody else out there who are ahead of us?
Here's a console printout from Xilinx's iMPACT FPGA programmer, as it loaded Xiangfu's test program onto the Spartan-6. (I will post a video of the prototype Control Unit later.)

Hi flyonwall,
I would like to ask for your opinion on BFL offer we got today at https://bitcointalksearch.org/topic/65-nm-chips-bfl-accepted-100-escrow-by-john-k-group-buy-1-kernel32-223571 .
They are willing to sell us (as GroupBuy) advanced 65 nm chips (4 GH/s per piece) on 100% escrow (John K.), on-time-or-deal-is-off policy.
Is developing and producing mining boards capable of running those chips more challenging than for Avalon's 110 nm ones? Would you be interested? (Avalon boards are surely to stay the top priority.)
Since, I'm refining the deal right now, I can use any suggestions about documentation, sample chips etc. I should require for you/other developers as part of the deal.
Thank you.

Hi Kernel32,
I have a Jalapeno order in place with BFL since February (Order #100016514). I will not invest any time and effort on their chip until they deliver my order. Also, once they deliver my Jalapeno, I will look inside and give you my opinion.
Edit:
They can't just jump to my order either, forgetting the rest of the people ahead of me. I will accept my Jalapeno if they decide to deliver it ahead of the others, but I will still not spend any time and effort on their chip if they simply jump through to my order. The reason is that, by this time, if they do really have chips in production, they should be delivering systems at a fast clip. They are not, so giving me a favor at the expense of others would tell me that the whole thing is suspect. I just can't believe that they are selling chips now so other outfits like me can deliver the systems, instead of having people wait for them. If this were true, would they be willing to fund me to build systems for their current customers? If they need help delivering the systems for their current customers, I can help; but they (BFL) would have to pay me first in order for me to do it.

Welcome to the Beach Side condo, BitcoinLady!
Welcome to the Beach Side condo, frontbit!
Frontbit bought his condo along with 10 chips from the Aprtil 30th order. I gave those chips to him at 0.19 BTC per chip. The price of those chips has just increased to 0.29 BTC per chip.
