Thanks cet for your suggestions, but it didn't work, rPI is boots normal.

This far I tried:

- new SD with new image
- new Raspi (and config.txt with avoid_safe_mode=1)
- other psu
- other router/switch/utp cable
- contacting BFSB....

did you try using ssh, then the command:
nano run/shm/.stat.log

it should display all the chips/boards that the system detects. If your miner is giving errors about no chips, this would be the place to check and see exactly what the miner is doing

try different banks on the mboard.

Thanks Foo but I tried this allready.

Does anyone know what this means and/or how to solve ?

Code:

pi@bitfury:/opt/bitfury$ sudo ./start-miner-console.sh
INIT: 0 chips detected
Floating point exception

My Bitfury starterkit stopped hashing and refuses to hash Sad

I had the same problem with my other starterkit, that one never worked.

Mailed BFSB several days ago and pm'ed P but maybe someone knows something that helps ?

if the rPI is working.. then try changing the bank the h-boad is plugged into.

if the rPI isn't booting, then re-image the memory card.

For the Easter egg hunt - these are my guesses (I hope they're right).

Hardware:
The hex string on the edge of the m-board is part of the coinbase parameter from the Genesis Block (Block 0) on the main network.

Which decodes to: 04ffff001d0104 + "The Times 03/Jan/2009 Chancell"

See: https://en.bitcoin.it/wiki/Genesis_block

Software:
By default, in /opt/bitfury/proxy_pools.conf
The usernames for each pool is set to the Bitcoin Foundation's donation address (Seen here - 1BTCorgHwCg6u2YSAWKgS17qUad6kHmtQW)

I am going to complete your unfinished solution

First block ever solved on the network, 2009-01-09 02:54:25 - this block and its 50coins were mined by satoshi (they are still unspent within the address)
https://blockchain.info/block-index/2
The genesis block (https://en.bitcoin.it/wiki/Genesis_block) contains the phrase "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks"

...
Also: did you notice the different voltages the chips get, compared to the output of the voltage regulator? At least the caps show different readings, didn't check at the chips while running. Could there be a current/copper cross-section "problem" on the boards?
...

on the v1 h-boards, i measure voltage across the caps (not the regulator) and find that of 2-3 caps sampled the voltage is within 0.005V range

Thanks for replying!
I suppose you compared caps from different groups, as the ones close together of course must have nearly the same voltage?
On all my boards (overvolted, Aug., and Oct.) there is a difference between every group which is big enough to have significant impact on the chip clocks. The biggest gap is on the longest current path, between the caps beside the voltage regulator and the group farthest away (upper left, chips 3,4,5,6?). On the October boards without caps it is about 0.03V, on August ones about 0.015-0.02V.
Seems not much, but we are talking about 0.6-0.9V core voltage!

In the meantime I tried to support the current distribution: only one (really) thick wire (mV drop at 15 Amps!) on the longest v+ path already makes a noticeable difference and reduces the voltage drop to about 1/2. The hash rates for the individual chips are much more even now. I am sure, doing the same for GND and the other groups will improve performance further.

Update:

Good news everyone! We practically finished packing all of 700's last week. About half of them were also shipped, and the remaining ones will be going out on monday or tuesday with whatever else we'll have packed by then. My team is confident that we'll have all remaining orders out of the door within 2 weeks, and if we really manage to pull it off I would then reopen sales for immediate shipment of v1.2 H-cards and hopefully also our new stuff! (more about this later when I get my hands on them)

For those of you receiving your first units, there should've been an instructions sheet for setting up your miner inside your box.
If yours came without instructions you can download it from HERE.

We're also preparing a datasheet for the chip (it's currently in russian only).

And last but not least I was given permission to release our M-board and H-card schematics to the public!

Download in zipped eagle .sch format here:
M-Board v2.3
H-Card v1.2

Hi Punin,
Any changes of 3D CAD files (e.g. STEP/IGES) being made available?

nice
ps: any price change for v1.2 Hboard when you are going to selling again?

Hi,

are your October h-boards also that much different? I have only one of these, so I don't know if it is only me...

Already quite impressive in stock condition, with voltage tweaked to 0.81V it runs even a little faster (~37GH) than both my August boards (~36GH at max. 0.84V) - and that with one completely dead chip!

Could it be the missing capacitors (the only difference I can see, aside from the already slightly changed R01F)?

Also: did you notice the different voltages the chips get, compared to the output of the voltage regulator? At least the caps show different readings, didn't check at the chips while running. Could there be a current/copper cross-section "problem" on the boards?

Has the reason/source of the overheating caps on the October boards been found? Maybe there could be some kind of relation (currents flowing through caps to level HF voltage ripple because of voltage drop)?

I don't have enough hardware (yet) to investigate as much as I would like to...

Disclaimer: Just some thoughts of a curious person, no offense to the designer(s)/distributor(s) of this great piece of hardware! Thanks BTW!

Normaly each of the boards can be pushed over 32 gh even with 1 or 2 dead chips ... my 10 boards old august and new oct run at 360+gh ... stable ... if stability is problem try to run the board chips at 53 clock

I ordered a 2* 25gh cards in 1 order and in a separate order 14 *25gh cards and a starter kit, not a 400gh unit. That means I should be guaranteed a minimum of 25gh per card.

So far no reply to 2 emails. I have 2 junk boards they sent me and im furious about it really. They were both rev 1 boards, 1 had 11 dead chips, the other wont go over 20ghs...

The one that works at 20 gh is considered a good one
