Help w/ Firmware for 2 TH/s A1 miner

[Finksy]

Just received a 2TH/s Dragon miner.  Miner was shipped without SD Card, no help from seller or manufacturer.   

I have dowloaded a few firmware images I found online, including the latest Coincraft Desk model and an AMT A1-based miner, and am currently working on downloading a full backup image from a 1TH dragon miner by torrent, but at current rate will take 3 weeks to complete.

Can anyone help me?  W/ the coincraft image flashed to an SD Card, the RasPi lights up and computer shows network activity, but IP scanner doesn't get me any hosts.  Tried hooking it up to the network, no IP address to be found.  Not sure what to do now.  Will give BTC tip for help with this.

Have you been able to sign into the RasPi while connected to a monitor? That should allow you to find the IP manually.

You cannot use the coincraft image to power these. Look here: https://bitcointalk.org/index.php?topic=768695.msg8663022#msg8663022

I am pretty sure he posted a link to the image.

There is no image posted in that thread.  Here https://bitcointa.lk/threads/the-install-instruction-and-trouble-shoot-of-1t-dragon-miner.290633/page-2
 you got a firmware image off another member.  Any chance you could hook me up?

Yeah. Thanks for reminding me, let me see if the link still works.

Just found a full image of firmware for 1T dragon here: https://bitcointalk.org/index.php?topic=545642.msg5957256#msg5957256

Going to try it out, fingers crossed.

Here is the one I used.

Have not had a 2TH to test with but here is one 1.5 lketc comes with: https://bitcointalk.org/index.php?topic=768695.msg8663028#msg8663028

For 1TH/2TH Dragon you can use this image http://pan.baidu.com/s/1mguolfy pass:2vjs (ip address:192.168.1.113)

The image for 1.5T Dragon shouldn't be compatible with 1T or 2T Dragons since the number of chips per blade is different (10 for 1.5T to 8/16 for 1T/2T).
With this image you should be able to downclock (tweak the voltage and frequency via device's web interface) the device at some point in time when the electricity costs equals mining profit and extent miner usage further more.

Cheers.

Have you tested this?  I don't know on 1.5 but i am pretty sure the firmware detected how many blades.   There are a 5 and 4  blade 1T, to my knowledge i believe the same image worked on both.

I could be wrong as I have not used a 2 T just the 1.5 and 1.

[sueche]

Yes, I have tested this FW on 1TH Dragon - 4 blades but not on the 5 blades version (I don't have with 5 blades, but I am pretty sure it would work). Actually this FW is used by the factory for testing and tweaking purposes.
On 2TH Dragon should be the same as for the 4 blades Dragon 1TH - simply there are 8 boards with 8x A1 chips assemblings, insted of 4 boards with 8x A1 chips.
But of course one have to test it to be 100% sure - somewehe I've seen this firmware on 2TH Dragon but can't recall exactly where.

i tested this image on 1.5th version. shows 5 blades and can change the clock settings. just a short try though. the hashrate does goes up & down after changing the freq's. not too sure what to change them too but i opted to change it to the 9xx range.. it's all in chinese if i'm not mistaken. sadly i forgot to take a screen shot of it. might try again in the next few days. yes the default ip address is 192.168.113. not 100% sure if it works 100% but for sure it works but only on 5 blades. when i click on the real time monitor tab it shows 6 blades but of course only 5 blades are tweak-able also the amount of chips that are tweak able  8 chips instead of 10 chips if i'm not mistaken hence it does show the blades are at different speeds. more testing to find out more & of course will appreciate if a version for the 1.5th is available. more likely using it to downclock instead of over clocking.

hope someone would find this useful & share more info. thx to sueche for uploading & sharing the image.

The image that I've uploaded is explicitly for 8xA1 chips on blade (1 or 2 TH Dragons) - you can use that for over/under clock the miner - be careful overclocking the 4/8 blades versions ! (the image has got English language version link on top right of the screen).
For 1.5TH Dragons (10xA1 chips on blade) try this image - it is the last official factory version I have.

If you need the 1.5 here is image mine came with - https://www.dropbox.com/s/so2wrtqbqd6jzzs/Dragon1.5boot.rar?dl=0

Link should be up for a few months .

But with 2 TH I don't think this is image you are looking for.

[yslyung]

many thx guys, i have the same img for the 1.5th version. but can't do much, no tweaking

[sueche]

Well, I have one of my 1.5T Dragons with a little bit different image (I thought it's the one I've uploaded), which allows tweaking the hashrate between:
Freq    ->hashrate
750     ->1.44T
780     ->1.50T
800     ->1.53T
820     ->1.57T
850     ->1.63T

Also the web interface can be locked with a password (only for pools changing) - all other settings can be changed without this password.
Check this out:


As for the 1T/2T image refer to: http://bitmine.ch/coincraft-28nm-asic/
As you can see in nominal voltage mode "...0.765 V in nominal" you should set Freq to 800 (25GH/s per chip, 32 chips) and voltage to 0.765V to achieve best results (like 0.78 W/GH) but only with proper PSU like Corsair RM1000 (it can't be achievd with the stock one) - measured with powermeter: 640W@wall and hashing @820GH/s.
That should put the miner in normal instead overclocked mode (like they come from LKETC) - I am reffering the 4 blades machines (for 8 blades 2TH Dragons should be similar). 1TH Dragons (5 blades) were in normal mode comming from the factory.

the one you uploaded is with the tweaks as the pic here ? i'll download it anyways & try later today. will report back. it looked like the same stock fw (by the file name).

the 1.5th dragons i have came with the stock standard 1000w dragon psu's, but i have hybrid the miners by using the stock psu to power 5 blades & the 6th blade is powered by another psu so i should have some "extra" juice to test but i will test it out 1st before doing anything else.

many thx again. if the one you uploaded is not this tweakable fw, please do upload it. would like to try it out.

thx again.

Not sure the one I've uploaded is the same as on the pic, you have to test that by yourself. If it's not I'll have to extract the image from the miner's SD card - that would be the only way. The one I've uploaded was the last official image on their website and I thought it might be the same - never tested. I wonder why would you try to "have some "extra" juice" these days at current BTC prices. I would rather go other way round - underclock (of course it depends on your electricity cost).

if it's from the website then it;s not the one you have. greatly appreciate if you could extract it out.

many thx again.

most likely underclocking it to reduce the huge amount of hw errors. like i said earlier will have to test it out and see which direction it favors.

Here's the image from the screenshots above for Dragon 1.5T.
File format is .imgc - [compressed image] - you can use HDDRawCopy for writing on SD card.
