Looks like people really like those BW sticks. Won't do much for dev funding but the software guy will get paid, so that's good news.
Rather looks like a stick based on the BitFury chip might be in order later on eh?  |

Look at the back of the PSU. On the left you will see a set of thin contacts -- those control the PSU. Do 2 of them have wires/switch soldered to them? The PSU needs those to turn on the DC output... ref:  Connect the thin brown and black wires together using a small switch and the PSU then supplies power. Green LED will turn on showing that. |

Did you try the reset button? I have never tried it but someone gave suggestions on how to use in the main S9 thread recently. It was something like, disconnect all the hashboards from power and from the control board, boot it up, hold the reset button for more than 10 seconds, let it reboot and wait 20 minutes. Go look for the exact directions though because I may be getting it wrong.
Close. (and it was me) Power down, remove power leads from hash boards. Leave power leads connected to controller. Turn on power, Wait a few seconds, then press the reset button and hold in for ~ 10 sec. Release button and leave it alone. The red led by the lan port should flash a few time to tell ya it's resetting. At this point, the older s9's needed maybe 5min at most. You should be able to log into the GUI and at least change your pool info. With the B16 on up or when using an older s9 with this new auto-tune software -- not sure. With no hash boards to fiddle with and speed test I have no idea what the firmware will make of it. Hopefully like with the older miners and firmware it will just shrug its shoulders and finish setting up the other parts of the miner... Probably would be a good idea to see what the Kernel Log reports while it tries to find boards Anywho, if you can get to the GUI and set pools you should be good to power down, reconnect power to hash boards, maybe slaughter a chicken or lamb, then power up and see if the gods have been appeased... |

First of all thank you all for your support. We all rely on it.
I've never had a reason to post, before now.
I would like to take home a part of history, but perhaps one I can at least stick somewhere on solo.
Not to rock the boat but .15 BTC for a functioning BW miner
Then I raise my bid for 1 stick to 0.15 BTCSorry Phil.... That puts bidding for 1x stick of the 3x available to: Eagleone 0.15btc gt-addict 0.15btc NotFuzzyWarm 0.15btc so if I bid .16 the standings go to phil .16 gt-addict .15 Eagleone .15 NotFuzzyWarm .15 but bumped> and Not FuzzyWarm gets bumped since he bid .15 after the other two bids of .15 NOTE I did not bid this .16 yet but I am asking for clarification of bidding rules. Good thing no edits are allowed here. So I did not bid the .16 yet waiting on a ruling. Then I enter a bid of 0.175btc for 1x to be well ahead. Now leading the pack. |

I compared pics of a s9 b11 hash board to the b17 and the Vcore regulator sections look identical.

Can people share the file names of any firmwares they have downloaded please? I am interested to know what versions exist. I am aware of these:
s9-20160622-650M-for-low-voltage.tar.gz
s9-20160624-650M.tar.gz
s9-20160624-600M.tar.gz
s9-20160624-550M.tar.gz
Antminer-S9-201607131442-12.92T-600M-security.tar.gz
Antminer-S9-201607131442-11.85T-550M-security.tar.gz
Antminer-S9-201607131440-14T-650M-security.tar.gz
Same as what I have for the s9's sans the 550M one. All miners I bought were the faster batch releases  And of course I have a copy of the latest release but it's not getting ANYWHERE near any of my miners. |

Given the support for SHA-1 and SHA-2 at 256 bit, it MIGHT be possible to write a kludge program to get it to mine Bitcoin - but it's not going to be competative with a Bitcoin ASIC unit.
So on a PRACTICAL basis, no.
Exactly. Cards like that are for secure end-to-end encryption/decryption of data, mainly banking transactions. For that use the keys are known to both parties at each end so they are not trying to 'crack' the hash, just process the data streams in/out. AMD has some monster GPU's geared exactly for that use. Truth be told, 16nm chips for those specifically targeted at Banking and other Financial xfr usage is something like >50% of AMD's chips that they get from TSMC with the rest being for more mundane 'regular' GPU's and support memory chips. |

I haven't really probed but based on behavior I would guess the micro toggles the main buck's enable line. This was not on the S7. I would also guess but I haven't confirmed that the buck might be hardwired for a particular voltage. The one I looked at today, two adjacent boards had two different voltages. Since it's someone else's machines I'm not willing to poke around on 'em to see what goes where and does what, but if the buck is the same as S7 (looks like it at a glance) the DPOT is left unpopulated. I'd be interested to know if that's the case on the new version. If any of y'all have a board shoot craps and open it up it'd be great to get some high-res pictures of the regulator portion of the board.
Pics of s9 b17 Vcore regulator section: Font side At least this looks near pristine!. That same area on many/most of my older s9's sorta look um, like someone spit on it and it dried... (seriously, doubt that is it more likely flux residue from bad cleaning). Nasty looking and highly unprofessional.  Back side showing no U2 DPOT. Also R17 coming from a bus of some sort going to U2's pin-6 along with R101 and R102 are missing as well. 101-102 run between the DPOT and programming plug P1 pins 1 & 2 that was used for Sidehacks s7 undervolting mod. To me, bottom line is that the PIC has direct coms with the Vcore regulator which from a design point makes perfect sense. I mean, since many/most regulators have internal EPROM or flash to store safe startup values and are quite happy to talk to a micro-controller once the uC wakes up, why add another layer (the DPOT) to things? Have all s9's been like this? Guess I gotta dig up pics of the bad s9 boards I sent to Bitmain Warranty...  Now to wait for the miner to finish playing with itself and get back to work.... edit: And 15min later -- back to full speed  |

Plus they pulled all the older firmware from the site.
Which is why for all miners I've had I always made sure to download/save the different versions shortly after they are released. I usually do not apply the updates but at least I always have the software in storage just in case this happens... |

Anyone here know how to ssh into the s9 and grab a copy of the on-board (part of the ARM based SOC) flash firmware aka the Factory Reset image that the controller uses when mounting the working partition(s)? Sadly, working knowledge of any 'UX is not one of the many hats I wear For 1 it would make for a damn fine way to have a real backup vs just a settings file the 'backup' function does for us. For 1 I suppose the resulting file should be a directly usable xxxx.tar.gz file. |

Tell ya what, considering that if a board in my b17 miner goes wonky I'll see what Bitmain Warranty can do about it vs sending to China, I'll look tomorrrow. Reason is this post in the Official s9 thread https://bitcointalk.org/index.php?topic=1493601.msg16620404#msg16620404Leads me to wonder if the PIC/MCU/whatever now has a direct link to the Vcore regulator... From what I can tell on older s9's the regulator is identical to an s7. Even have a nice set of pins that can probably be used to program the voltage like an s7. edit: Have you had a chance to look at disassembled s9 (batch 17?) code at https://onlinedisassembler.com/odaweb/HP7GAkIN ? Way out of my league to dig into but the index points to many many interesting bits I don't recall seeing before... Damn that brings back memories! I haven't dealt with assembly code since the mid-1970-s through maybe 1982. Motorola 6800, Z80 and a few others. Trying to cram functional work-with-the-world code into maybe 128k leaving 32k of changeable user memory if you were lucky... Good way to make someone feel real old there... |

I just received my S9 and I got it up and mining. I noticed in that in the Firmware version that came with my S9, i don't have the option to adjust fan speed. This results in an annoying increase and decrease of fan speeds, kind of like a breeze with a slight whistle.
Is there anyway to downgrade the firmware so i can have access to customize fan speed percentage under the "Miner Configuration" page?
Model GNU/Linux
Hardware Version 4.8.1.3
Kernel Version Linux 3.14.0-xilinx-gf387dab-dirty #38 SMP PREEMPT Fri Jun 17 20:02:51 CST 2016
BMminer Version 2.0.0
batches after 16 can't work on old firmwarethat what they told me on there support We should press them to allow us to manage fan speed its more disturbing than the previous Interesting... Anyone have a Batch-16 miner to tell us what version of BMminer it is using? |
|
|

Very cool.... looking through the index I see lots of v adjustment code. Now question is: does the PIC talk directly to the Vreg or to a DPOT? |

I know most folks don't really take stuff apart, but can someone confirm whether or not the new-batch S9 boards have the U2 digital potentiometer populated? The ones I've looked at from older batches don't, and I haven't seen any adjustments in voltage during startup so I wonder if these aren't made for a fixed core voltage. The new ones look to be adjusting voltage on the fly, like S7 boards should have been capable of, so either they're doing something unexpected or that dpot should be on there.
With the miner & fans running you kind of see the area where the U2 pads are but I couldn't really tell 'cause the fans blur things... Maybe a well-timed flash could catch it. A snippet from the kernel logs shows they definitely are doing something to control Vcore on-the-fly. use PIC voltage=870 on chain[5]
now set pic voltage=125 on chain[5]
use PIC voltage=870 on chain[6]
now set pic voltage=125 on chain[6]
use PIC voltage=870 on chain[7]
now set pic voltage=125 on chain[7]
enable_pic_dac on chain[5]
enable_pic_dac on chain[6]
enable_pic_dac on chain[7]
set command mode to VIL |

So it would seem like upgrading to the latest FW on the website on old miners is not advisable right now is that the general agreement here?
Grant you so far we have few data points but -- correct. For the old miners, if the original/older firmware works then I say do not upgrade. Most of my miners except the B1 (changed to low voltage version) are running the firmware they shipped with. As for applying the new firmware to the batch-16/17 miners, I am going to wait a bit to see any problems other folks have before *maybe* upgrading. |

Ouch!!!!
One trick I learned after munging a s9 Frimware: Unplug the PCI power to the hash boards and power only the controller.
Power up, wait several min and see if the Bitmain GUI reports life (socket connection error goes away).
If no go, still only with controller power, press the reset button for ~ 10sec then release it. Wait several more min to see if it lives. If it is alive you should be able to set pools, etc even without the hash boards working.
If it comes back to life, power down, reconnect power to hash boards and pray everything works....
