1  Bitcoin / Hardware / BFL labs single 60GHs power on but no mining on: April 11, 2016, 06:13:47 AM
Hi all after a long time.
Yesterday i found my BFL single 60GH/s machine sitting lazy and watch me.
It said to me: Am i dead now? After those years of mining?
So i decided to give it a chance and give it life again.
Now i 'm more prepaired.
I do have a USB Blaster JTAG, AVR Studio ver 5, quartus ii web and free time to spend.
The symptoms are:
Giving power to the device, power led on, and one more led too but no led near usb plug lights.
Measured voltages 1V, 3.3V 5V 12V ->OK
Connecting to PC through the USB cable, the PC with XP sp3 recognize it as COM4 serial converter.
I read the FTDI 232H chip through his programing software and finds it.
I did reprogramming this chip with the lightfoot's XML file. OK
I try to mining but the cgminer recognize it as ICARUS and refuse to mining.
Does anyone can help and tell me if and how i can reflash it somehow?
Help my lazy sitting BFL single 60GH/s getting back to life again.
TIA

Thank you all for replies. The next question is: How can i reflash the board with the latest firmware? What stuff should i have to do it and how?
I will try a new (and final) try to revive it and if not success i 'll give up  Sad

When you say "Usb port is not recognizable although the win 7 pc i have found it as serial converter." do you mean it comes up as a usb serial converter or is windows saying the usb device was not recognized? I do know several people have had issues with the FTDI usb->TTL uart chip dying.

Sounds like everything else is working from your descriptions. The LED should blink when power is turned on, then blink fast a few times and go solid light. That means the hashing ASICs have passed the self test.
Answering to post i must said that lighfoot helps me somehow by PM. Thats for the member who asked.
The other thing now.
The win7 OS recognize it as serial converter. When i try to connect with bgminer it says "no device" or something like this.
Then i give the device manualy as \\.\COM3. After a couple of seconds the bgminer gives errors and try to reset the usb.
After many tries i didn't manage to make it work. I don't know where to search.
Also i changed the eeprom U10 with one from jalapeno and lost the COM3 port detection.
I put it back and i have again the COM3 port available.
I'm not sure but is it possible to check somehow if ARM controlers are working or not?
Any help would be appreciated

My progress so far:
I 've do some measurements to oscillator crystals and i have a clear sin waveform from both crystals. So i believe that the arm processors are working.
I 've also found that NO data came into U10 eeprom 93L56 chip. I decide to take it off and replace it with a fully working jalapeno eeprom. Is it good or not?
Voltages seems OK accorging to schematic SC ver 1.0.
The easyminer from bfl recognise that there is a device detected but it won't opening for mining proccess.
Other mining software like cgminer don't even detected. I guess that either the ftdi chip is not working or the eeprom is bad.
Any suggestions?
TIA

Thank you for reply. As i said, i've manage to do some measurements already. I have the schematic from version 1.0 but there are many differences like test points
missing from that schematic.
i will check if the crystal oscilators are oscillating and some waveforms too. By the way, i don't pay a penny more to get a new one single since it's not worth to mining
with 60GHs in our days. I will do it for fun and educational purposes only. If i had money to invest maybe i would buy a more powerfull mining device above 1 THs or more.
So now i need only technical advises and sugestions.
Thank you again anyway  Smiley

Hi all,
my single 60GHs is dead and i want to revive it (if possible).
Machine is opening, the blowers runing fully and after gows lower speed.
Usb port is not recognizable although the win 7 pc i have found it as serial converter.
I try to mining with all known miner software like easyminer, bfgminer,cgminer etc.
Nothing happened also.
So i've decided to do some measurements to find a clue.
+1V are exist in both test points and others test points has 1,8V, 3,3V, 5V seems OK.
My last chance to fix it is to take out the eeprom 93LC56, read it and replaced.
Please before i do that if someone has another approach about measurements etc, post it here.
TIA

Maybe but as said: "hope dies latest" Smiley
I want to try fix it not for btc but for fun and educational. 60GHs in our days is almost nothing but it's a good PCB for practice.
My last chance is to check for short circuits and try to eliminate them if any.

Good news and bad news.
The good news is that now the cgminer says: bitforce detect : etc...
Bad news is that after many tries and driver replacements the miner never connects to a pool and the screen says: ZOMBIE

What can i check further inside to debug the fault part?
TIA

I don't think the problem only on FTDI chips. There might be another part of miner already damage.
Maybe but for now the only thing i can do is replacing the chip. My question is:
What do i need to make it work? Should i pre-program it first and how? Or can i put it as it is?
Please anyone describe the proccess.
TIA

Dear friends,
recently my single 60GHs miner from bfl labs stops working. I need some technical advice here.
Before one week my miner stoped. I 've noticed that both the PC and the miner is dead too.
The PSU of miner (the black bfl labs psu) has catch up fire and burns the PCB.
When i fix the PSU and measure it the output was 13,8V DC at 20 amps current rate.
I 've tried to power the miner and the device starts blowing at first and after it stops spining the fans and remains at low speed
which is normal. So far so good.
But unfortunately when i connect the miner to a host PC the USB section of device doesn't work.
I notice a small resistance beetween pin 6 of the FTDI chip and ground.
When i put this IC off the PCB the small resistance goes off to.
I 've already order a new one FTDI chip from ebay.
My question is: What do i need to put the miner in working mode again? Do i need to program the new chip and how can i do that?
I have a multi programmer for some EPPROMS and PICS too but i don't know if i can do it only with that.
Any help would be appreciated.
TIA

It would be very nice and helpfull to have all this parts in a KIT form. Of course this is not a task for novice users and better bring the KIT to the pro's.
I 'm interesting if someone has it in a KIT form but also i'm interesting even for PCB only.
TIA

The up to date versions are at https://github.com/zipiju/klondike

Thank you for imidiate answer. One more thing. Is it any KIT available with all parts and PCB (except avalon chips) paid by us $ or euro's.
Thank you again  Smiley
13  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: January 09, 2014, 10:16:17 AM
Is it possible to inform me where i can find the latest bugless version of this K16 project? It's diifficult to search so many threads.
Also i want to know if someone has it as a KIT. I have 18 avalon chips to test Smiley
TIA

Welcome back Chris Smiley

I can fully understand what you have passed since i 'm in the same situation you are now and if everything goes well, i will recover my health sooner than 3 months from now.
I have my 18 avalon chips available and i like to get involved in this K16 project but because of my illness i can't make PCB of it. Also i like to buy a KIT like with PCB, usb loader, parts, etc. Are there any like this available?
I can only pay through paypal because BTC price is increased toooo high! Please PM.

I wish you the best !!

Please help. I have 18 chips ASIC available and i need the PCB and parts to build my K16 system. Are there any KIT with PCB and all parts (except ASIC's) available to buy it through paypal? It is almost impossible to convert in BTC due to dramatically increase price. Message me by PM for price and time delivery as well.
TIA
16  Bitcoin / Hardware / Re: Liquid Synergy Designs Inc. -ASIC mining hardware on: November 12, 2013, 12:19:54 PM
Hi. I 've got my 18 chips and i want to ask if there are any KITS available, inlcuding pcb and all parts. I will do all the soldering job my self. I have BGA workstation available.
Because of dramaticaly increase bitcoin rate up to 300$, i regret not doing it earlier but due to health reasons i couldnt.
17  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: June 26, 2013, 06:18:51 AM
Step by step to success! I will be very pleased if i have permmission to post an article about klondike project progress so far. Keep up the good work!

I put their hardware presentation page in an article to my bitcoin hardware related site as we do with all the DIY projects available today. We also send them an email asking more details and offers but we receive autoresponder emailed typical answers.

BTW if you have any DIY project about bitcoin mining hardware, we will publish it.

Title: "The ASIC project"
here is my small script idea:

First, Some abreviations

GB= Global bank = the ultimate bank on earth
NG= National Goverment (elected by forcing peoples mind)
chip=small electronic device used for Bitcoin mining
BAM=Bitcoin Auto Miner based on cheap components affortable for public.

Earth 2015
Gloabal Bank has all the necessary hardware to do worldwide mining with huge profits.
To achive this, hundreds of "accidents" happened with the most important, the "suiside" of the CEO Dr Manix who invent the chip for the BAM
His lab burned from fire. All the notes from his designs are totaly destroyd (all of them?)  Wink
Before he died, he gave to his son (Dave) a small usb flash memory with ALL the info's about the project.
His father's girlfriend Monica, (secret agent hired from NG) try to find him son and get the flash.

National goverment forced by global bank ( ) gives away millions of $ to find any informations about the Dave's team
(hackers from his College) who try to protect him.
Mike (one of them) has a father named John (former agent joint US special forces) who realised what happened and try to help him..........


Hope that helps a little
Big story with continue action and suspense
