TL;DR
This post is about an image of the latest firmware of the well known Dragon 1T / 1.5T / 2T miner with my enhancements.
---------

If you have any issues, disable voltage and clock tweaks (see second post) and / or try with one of the stock firmwares first. They are linked below. Please report back any issues!

I did a little tweaks here and there after getting my hands on a Dragon Miner 1T recently. As there are still people looking for the firmware on this board, i created an (imho clearly!) enhanced image of the latest firmware of the Dragon 1T (and higher hashing) miner.

Firmware Changes
The firmware was upgraded with great care to make sure everything is running smooth.

Main features

• Voltage and Blade Clock can now modified on ALL hardware revisions (via SSH)
• Optional Stratum-proxy included!
• All relevant Security Patches have been applied
• Base Distribution is now Raspbian with important components from "jessie"
• Web interface was completely refurbished and is now password protected and more mobile / tablet friendly
• Upgrader miner.php from https://github.com/ckolivas/cgminer.git (https://github.com/ckolivas/cgminer.git)
• Miner-Jobs (cgminer) and Hashrate are monitored via "cron" and are restarted automatically if required
• SSH Access configured
• Logs are rotated to ensure disk does not run out of space
• Added a link to this thread as reference to the landing page
• Activated modest overclocking for RPi
• Properly configured LOCALES (en_US.UTF-8)
• Filesystem cleanup and reduction to fit SD cards with at least 7.7GB
• Removed Chinese and Russian language interfaces
• Removed useless info.php file
• ... and the cgminer version from the 2TH image (works for all Draon Miners)

Original Base firmwares (for troubleshooting or if you want to diff for some reason):

• 1T Dragon Miner DragonMiner1T_OriginalFirmware (https://www.dropbox.com/s/34101h25ktelhr2/DragonMiner1T_OriginalFirmware.rar?dl=1)

• 2T Dragon Miner DragonMiner2T_OriginalFirmware (https://www.dropbox.com/s/vey3gk9m7lotauc/DragonMiner2T_OriginalFirmware.zip?dl=1)

Credentials

• The preconfigured IP is 192.168.1.254 with a Gateway of 192.168.1.1 OR provided via DHCP (see download options).
• SSH login into the Raspberry with "pi" as username and "raspberry" as password.
• The username of all password protected pages is "admin" and the password is empty.
• You can change all relevant parameters via web frontend or by SSHing to the Miner / RPi.

Donations
There is absolutely no auto donation or hashing code in this image.

I am working as Senior Linux / Security Consultant and enjoy tweaking miners as hobby for almost three years now. If you want to donate some hashing, just let the miner run with my preconfigured workers for a little while or use the address from my signature.

Feel free to ping me with any questions.

Dragon Miner 1T Firmware Mod README

Requirements
To get started with the new firmware you need a SD Card, size at least 7.7 GB or bigger.


Firmware Download and Setup

• 1) Download the firmware from one of the Mirrors in the first post
• 2) Insert the SD card in a computer with an SD card reader
• 3) Extract the *.img file from the downloaded rar archive
• 4) Flash the image to the SD card (Guides for Linux, Windows and OS X here: https://www.raspberrypi.org/documentation/installation/installing-images/)
• 5) Power down your Miner if not already done so
• 5) When this process has finished, safely remove the SD card and insert it into your Miners Raspberry Pi unit
• 6) Power on your Miner and wait a minute until the SSH and web services start
• 7) Login to the web interface via http://192.168.1.254 OR via it's DHCP assigned address at http://$IP

You can now change Pool + Worker settings and also IP address, Gateway and DNS if needed.
Press the "Ok" Button to activate your changes and reboot to apply them automatically.


There is a small bug that might prevent cgminer from starting if not all three pool fields are populated. Make sure you fill all entries for the moment.


Voltage and Clock Tuning
The image supports voltage and blade clock tuning for all Miner versions (that i am aware of). To change these settings, SSH into the Miner and modify the file /var/config/extraopts. Modify the variables "a1vol" and "a1clock" only!

Restart your Miner with to apply these settings automatically.


Extranonce support via stratum-proxy
The image supports stratum-proxy optionally. The proxy needs to be enables and pool settings need to be adjusted, too.

Howto enable and configure stratum-proxy

1.) Edit your pool info in /opt/stratum-proxy/stratum-proxy.conf (this is a partial snippet only). Of course, the pool must support extranonce, too!

Example:

2.) SSH into the miner and edit the file /etc/rc.local.real and remove the hashes (#) in front of the two relevant lines. Restart your Miner with

to apply these settings automatically. You can access the stratum proxy web interface at

http://192.168.1.254 OR via it's DHCP assigned address at http://$IP[/li][/list]

3.) Last but not least, you must change your pool settings to point cgminer to the local stratum-proxy. The defaults are 127.0.0.1 and port 3333. Restart your Miner with to apply these settings automatically.

You are DONE! ;-)

Troubleshooting
The default login for is username "pi" with the password "raspberry". Enter "sudo -s" for full root permissions.
Given a working network connection, the cgminer jobs will be started automatically. If it does not work for some reason, login via SSH and check the output of "/var/www/run.sh". A good starting point is also the process output list. Run the command with as root to see all running processes. cgminer and stratum-proxy (if running) should be clearly visible.

Thank you!
I will get mine in a week, I'll definitely try this firmware.

Is there some kind of "hidden donation"? Something like 15min/day of mining in your pool?
I'm asking because a RasPi firmware made for bitcoin mining does this, and I've read that this is something "hidden"

That's a good question, thanks for bringing it up! Will add my answer to this thread.

The image does not contain anything like that. If you want donate a couple of Hashes, just let it hash for a while with my preconfigured example pool settings or use my signature address :)

As soon as you change the pool settings in the UI,  press the submit button and restart, your settings are applied and stay. Please take my word on it.

Additionally, everything is open source - nothing is obfuscated and everybody can take a look.

Thanks for your answer.
I was not implying that, just wanted to be sure that, if you were using the said custom OS as base (which I don't know), you removed that thing.
But now I see you're using Raspbian as a base, so, great!

Another question: does the small LCD screen work with this firmware? What does it show?
Thanks

Anyway to change the pre-configured IP?
If my gateway is 192.168.1.254, I would not be able to connect to it to change the ip address after flash this image.

This is the original, updated firmware (also using Raspbian, but way older!) with my enhancements, so i guess it is still this:
http://g04.s.alicdn.com/kf/HT12SFeFJVfXXagOFbX2/220654952/HT12SFeFJVfXXagOFbX2.jpg

It did not test it since i have no such device, but considering this as feature request - i can probably make it show whatever you want in case it does not work. For me it was not interesting even if my devices had LCDs, because i tweaked the webui for this to be more tablet friendly  ;)

Just try it and get back to me with any questions if it does not work. It is probably a piece of cake to get it working, but i might need feedback from you to get the device ID that connects to the PI.

You can either hardcode the IP of your local computer to eg 192.168.1.2 and change it the IP after connecting to http://192.168.1.254. I will update the README with the following short instructions.

Mini How-To

• 1 Disconnect router temporarily
• 2 Log into Miner web interface at http://192.168.1.254
• 3 Change Miner IP address
• 4 Reboot Miner
• 5 Re-connect your Router

If by all means you can't do it, i am happy to create a version with the desired network settings for you.

Great work! I also have my gateway as 192.168.1.254 so would definitely vouch for an image with reversed assignments, i.e IP of 192.168.1.1 and gateway of 192.168.1.254 (that despite the notes above).
Once again, great work!
PS. What version of cgminer does this ship with?

Ok, i will create and upload an ALTERNATIVE IP version tonight.

Included is the manufacturers Cgminer version (3.9) and it is not upgradeable without a decent amount of reverse engineering. It is a precompiled cgminer with a proprietary driver for the blades.

Definitely doable for me, but not worth the effort imho as
* the miner is running ultra stable with my settings
* i had zero problems with all pools tried so far

Any chance at voltage/frequency control? I have some old 2.3TH/s dragons that allow full control, and have been looking for an image to under-volt the 1 TH/s dragon as a space heater.

Yes, absolutely. I guess you are refering to the web Interface, are you? If you need it soonish, i can guide you through the necessary changes to the index.php file.

Otherwise, i already thought about a simple switch to change between economic/undervolt and performance. Which cgminer options do you need?

Hello, you can indicate whether this firmware is compatible with my old BITMINE COINGRAFT DESK 1TH/S.

thanks

As far as i know, those are clones/rebrands and should work. I need to verify to be sure about this.

Do you have shell access and can give me the full cgminer command line?

New version online, changes:
* Support for more blades
* Two download choices for different IP address settings

Happy holidays everyone!

This looks epic man i do have 1 request can you make it support Extranonce subscription?
if you upload 1 that has it i will instantly try it!

TY for this version!

Regards Roderick

I can not patch cgminer for stated reasons, but it should work via stratum proxy as far as i can read. Shall i include a certain Release version? Please provide any possible configuration you have in min and i will do my best.

yhea sure if you can tell me how its done! i have no clue on how to sure give me a Release version. and what do you mean with [/quote]any possible configuration you have in min and i will do my best.[/quote]
regards Roderick

yhea sure if you can tell me how its done! i have no clue on how to sure give me a Release version. and what do you mean with It means: If you have a working setup or documentation  with stratum proxy, let me know  ;)

Good news, @roderick112!
Stratum-proxy proof of concept is ready and hashing a while for testing. I do not have enough time currently to do make it dynamically and fully configurable via webgui. I guess a Mini-Howto with 3-5 easy steps will be good enough, right? ;-)

Here is a screenshot showing the stratum-proxy web interface:

Happy new year!

@mxnsch

you are amazing a mini tut will indeed do! you are a god mate!

Regards Roderick

PS.if this works i'll donate ;)

Happy new year! to you to!

thx for the hardwork !

i have a version for the 1.5th/s that allows OC'ing the miner but i left it at default @ 1.5ths

I'll give it a try & see how it goes.

looking fwd to see more options & improvements. FINALLY we can login via ssh.

No more locks.

I don't see much changes except being able to access the miner via ssh, different background, it works with the 1th & 1.5th version using the same FW.

more or less same to me but will check it out.

thx again.

It is and will stay a nice hack based on the original.

The main differences are
* tweak your ass off possibility
* watchguard jobs that monitor hashing etc.
* supports an arbitrary number of blades
and of course extranonce support in the next upload

You can already tweak the blades if you login into the miner via ssh and raise their value to eg 1150. Would not recommend this without proper cooling.

New upload upcoming, including:
* versioning, this is version 1.1
* new cgminer version that was successfully tested with 1TH & 1.5TH versions
* a new html landing page
* new clean urls
* some small bugfixes
* extranonce support via Pfool's excellent stratum-proxy (0.8.1-SNAPSHOT-20151218, https://bitcointalk.org/index.php?topic=611338.0 (https://bitcointalk.org/index.php?topic=611338.0))

awesome ! some screenies will be nice !

waiting

Really good job! But still missing key feature - voltage control from www panel. I can underclock and undervolt 2THs Dragon at 0.5W/GHs @ 1THs.
 

That's imho not a key feature, that's a goodie. Parameters can easily adapted via ssh'ing in and changing cgminer arguments in index.php.

But please, just as i said:
Provide the cgminer command line and arguments and i can create a form for it. The minimum i need to implement this is the 2TH firmware download to look myself.

If you can not find it online, please someone clone the SD card of their miner and upload it somewhere. Thanks

Please ignore, found a working image and testing currently. I am currently testing if my image will work for the 2TH version, too and as far as i can see it will work ;-)

For the interested minds, these are the cgminer arguments parameters (that are specific to the dragon miners) that need to be adjusted:
--A1Pll1 (Blade 1 clock)
--A1Pll2 (Blade 2 clock)
--A1Pll3 (Blade 3 clock)
--A1Pll4 (Blade 4 clock)
--A1Pll5 (Blade 5 clock)
--A1Pll6 (Blade 6 clock)
--A1Pll7 (Blade 7 clock)
--A1Pll8 (Blade 8 clock)
--A1Vol (<- voltage)

Standard settings are (afaik):
* 800 (25GH/s per chip, 32 chips) and voltage of 0.765V.

Min-Max Clock values
700 - 1100

Min-Max Voltage values
600 - 890

Rest later today or tomorrow.

i have a copy of this but it's for 1.5ths version

https://i.imgur.com/Qmaxbh2.jpg?1

also do take note for those who intend to oc, not only voltages & temps, PSU has to be able to supply sufficient power ! many forget about PSU  ;D

Absolutely, stock PSU must be replaced for any overclocking.

Thanks, do not need the 1.5. The next image will work with all miners and speeds (1,1.5,2th) without manual configuration.

Wow, nice job mxnsch! If I had an A1 I'd definitely buy you a round or 2! Any chance you could improve A2 Terminator firmware also? That, I do have.  ;)

I guess this will be the last useful feature anyways as this hardware will become obsolete very soon.

Initially i wanted to look at Antminer s5(+) and S7 next, but will happily look at any Linux based firmware you throw at me with feature wishes. I will look at it as soon as time permits. A2 Terminator could definitely benefit from stratum proxy, too.   :)

Ok guys, good news.

I just finished my testing and come to the following conclusions:
* my firmware now works for all Dragon Miner versions
* This also means clockspeed and voltage will be controllable in the next firmware upload for ALL Dragon Miner versions (1, 1.5 & 2TH)

I decided against the web gui, but all changes (clock, volt, stratum-proxy) need to be done on one specific configuration file, only.

Last but not least here are some relevant numbers from my testing with min and max values for voltage and clock, tested with my 1TH miner (and the backported cgminer version from the 2TH miner):


Image will be finished and upload tomorrow night. Don't bother using the old versions meanwhile, the new one is much better ;-)

Have a great evening!

ths for the hardwork.

mind listing out the suggested volt & freq ?

yep dont bother abt older versions but i have over 40 of them to flash that does bothers me a bit though. grrrrr

will upgrade them 1 by 1. lots of flashing to do. dem.

I am still looking for the best values. I guess it will be around 600 voltage and 900 clock.

It depends on your electricity cost and hosting place (heat). For me personally, a Iow watts / GHs ratio is key. I suggest you test the new version after the upload is done and contact me via PN with your questions afterwards.

With 40 devices it might be an option if i create a more generic image for you with DHCP enabled for the relevant network interface. You can then simply clone the image 40 times to your SD cards.

Best wishes

Hello everybody,

the new version is up! Mirror 2 currently uploading. I kicked the 133 IP release and will create a DHCP enabled version tomorrow. DHCP will be first boot only and can be set to a static IP via web afterwards.

Changes and new screens are in the first post, i will update the second post with some instructions on how to mod the voltage, blade clocks and how to enable stratum-proxy.

Have fun and happy new year!

there's also a version with minera built in or i'd say add on.

thx for the hardwork will DL later & test.

You are welcome. Not by me, because i tested minera and imho it's not worth it on the dragon firmware because of the broken cgminer 3.9 support.  It is easily installable with one step now, though.

Links are not working, is it uploading?

I have a question: my T1 doesn't have a LCD display. Is that possible? I'm not sure that it's a Dragon Miner T1, that's what the seller said, but I'm sure it doesn't feature an LCD display (but it has a "hole" on the case, maybe it can be plugged in?)

Sorry, a copy and paste error, use this meanwhile: https://www.dropbox.com/s/s61kkl1b843ersj/dragon_miner_mxnschmod_firmwarev1.1_20160104_ip254.tgz?dl=0

Not all Dragon Miners have LEDs, but all boards can be equipped with an LCD by attaching a compatible one on the controller board. The Pins are there.

Hope that helps!

can not get to link https//www.dropbox.com/s/s61kkl1b843ersj/dragon_miner_mxnschmod_firmwarev1.1_20160104_ip254.tgz?dl=0

also will this firmware help with p2poool thanks chris

Use the download link in the first Post now (Mirror 1 & 2 are up now, links checked working).

What is your question regarding p2pool?

Hi iam using 2th dragon/a1 on p2pool and i lose hash rate  also on my 2 S7 miners
cheers chris 

Does this work with all A1-based miners?
I have one of the few 1.2TH units that AMT finally delivered to some of its customers. Looks like it is really from LKtec. Been running solid for over 1.5 years but your upgrade looks far better than what it has.

I guess yes, but do not know for sure as i dont own one. Do you have a download link for your installed firmware? I will know after inspecting it. Feel free to PM me.

What do you mean by "loosing hashrate"?

To answer my own question: It seems that some devices (like eg Antminer S2) have a loss of 10-20% of their hashrate, only when mining on p2pool. Unfortunately,  there is no (known) workaround or fix for this and can not be resolved without changing the ASIC driver and/or hardware.

I dont know if the Dragons are affected, but they are definitely not listed as compatible devices on the p2pool page in the Bitcoin Wiki.

Hope that helps nevertheless.

Not sure if I have an image of the firmware. Once this unicorn of a miner (rare) arrived after >6mo of delays I just walked away from the AMT/Bitmine.ch fiasco. I was one of the lucky ones that actually got something from the AMT/Bitmine.ch scammers   :o

I suppose I can always pull the card an make an image of it.

Wow, you must be one of those "happy customers" on the pictures 😂 j/k

If you provide an image, i promise to have a look asap.

Would a zip of the card work? I use HDclone at work and not sure if its 'smart' .img files which do not copy the free-space bits are usable by other programs.

'Happy"? Not by a long shot. A lucky one, yes and never ever to be seen in any AMT promo.
Ordered AMT's 510GH/s unit in Feb of 2014 for $4k, advertised as "ships within 4 weeks" unlike the 1.2TH/s rigs that were advertised and sold as pre-order only with to-be-determined delivery. I was sent a 1.2 TH/s rig only because they were all the scammer Joshoua Zipkin could get during his stay in China. That said, eventually actually getting 2x the hash I paid for vs folks that paid the full $8k for their TH/s rigs - several folks had waited since late 2013 - I was DAMN lucky.

The events are best covered in the Skype chats linked in my sig.

try to set queue to 0 or 1 when mining on p2p

i think it might be able to help a little with this new fw

I had no intention of making fun of you. The "lucky"  citation was directly from their website  :-\

You can use win32diskimager or you your clone tool. Free space does not matter as long as you compress the resulting img file, that's sure.
http://www.raspberry-projects.com/pi/pi-operating-systems/win32diskimager

Wow, this is cool. If I only had this fw a year ago... I don't have these beasts anymore but I will make a little donation 'cause I appreciate your work. Well done.

Edit: Sent a little donation.

Thanks! Maybe my next firmware is for one of your devices ;-)

@NotFuzzyWarm does your controller board look like this?
http://imgur.com/ZaY28kj

WOW new firmware looks amazing!  :o

could you maybe check on the links you have put up for the images they seem to not work  ???

thanks alot! you are amazing! again i'd downloading the firmware A.T.M and will leave it on you're pool setting for a bit TY! again

Regards Roderick

Hi,

the links work (for the 192.168.1.254 version), but you have to download it in a browser afaik. Please let me know if it still does not work for you.

Best wishes

Ps.: the dhcp enabled version will follow asap, family is a little sick today  :P

hello i dont mean the download link for the image wish indeed did not work via the browser download i get a 32gb img file  :P ::)

i mean this:https://gyazo.com/034142865e8adde6ff6b8ebc26ba5183

Regards Roderick

amazing i see you fixed the images! could i maybe p.m you a link you could upload the image to not compresed in a rar or other type if you're willing? would be amazing! TY again!

Regards Roderick

p.s. when it has been uploaded to there i'll give you a shared link from the server its on it has a 10gbs uplink/downlink! TY

Yes, i can upload it anywhere you like tonight - just pm me the credentials. Why do you need it rar'ed?

Images should be fixed, smf is a piece of crap....

Got you, the image is 32 GB unpacked for now as i had no time to rearrange free inodes yet. No reason to unpack, this is for Linux:
gzip -dc image.gz | sudo dd bs=4M of=/dev/$DEVICENAME

Images should be fixed, my elevated member status seems to have enabled more formatting options.

Stay tuned every - i am currently shrinking the image to 4G, but it will take a while to finish and upload fully  ;)

I will rar it then, upload and let you guys know here. Also some more configuration /setup instructions will follow.

Have a great one

Hello,
I received mine some days ago, the problem is that it's really noisy!
My idea was to keep it in my apartment, because I thought it would make the same noise as an old desktop computer, but it's way louder!
Do you have any hint about making it less noisy? Some replacement fants or something else?
Thanks

The stock fans are horrible! I replaced the fans with 4 spare arctic fans i had spare.
 http://www.memoryexpress.com/Products/MX49912 (http://www.memoryexpress.com/Products/MX49912)
Hope that helps! Got it down to 35dB.

Ps.: A new 8GB Image is ready, but i am on the road and will upload tonight.

yeah the file unpacked is way too big, using win32dskmgr, but obviously it would not fit onto the poor little 8gb card.

i hope there's aversion that can be easily flashed.

thx.

It is not too big for my 32GB card  ;D

Yes, i am currently testing a new 8GB version with some additional fixes. Upload today for sure.

will DL it & write later when ready. testing most likely tmr hahaha getting late at this part of the world.

waiting.

much thx ;)

I have 2THs version, so I used 8 pcs Sunon HAC0251S4-000U-A99 which are good quality, very quiet and very cheap (about USD4/pc), noise is less than 30dB and my temperatures are less than 50C. It is very similar noise to desktop computer.

Cheap and easy way is to use USD1/pc DC-DC buck converter from ebay which can lower voltage of original fans, but they are still a bit noisy even at lowest speed.

If you are unsure - AMA!  8)

Thanks, I just bought four. How noisy is yours? Compared to a desktop computer?

I'll be back home in two days, can't wait to try the new firmware!

As quiet as it can be. My gaming PC is louder  :D

Thank you, can't wait!

Can I ask you why the Pi needs overclocking?

It's not what i would call overclocking. Modest mode is really safe, but can also be disabled if you want. It's giving cgminer more CPU power. More relevant ist the memory that i adjusted for server runtime. It is
split.gpu_mem=16

Ok, I don't think I fully understand what you mean, I'll do some researches when I get home!
And will, of course, install the firmware!

post when a 8 gb card fits. waiting to test. did you allow-api by default & i think it should be standard port 4028 ?

hey

i got this old machine gathering dust. https://bitcointalk.org/index.php?topic=1155991.msg12196631#msg12196631 (https://bitcointalk.org/index.php?topic=1155991.msg12196631#msg12196631)

i tried your image and turned it on, added 3 pools and restartet it. but only runs 40gh..  >:(

do you think it can be saved or should i just throw it away.. ?



banneddk

Can you please deactivate the voltage settings? It should definitely work as long as the Hardware is not broken.

no hardware should be broken, as it worked when i got it, i just fucked up the sd card and lost the original image.. since then i havnt been able to find a image that worked...

next thing is, im no pro at putty/cgminer thing. so i got no clue on how to deactivate volt settings unless you can link a guide? i know how to enter putty and follow a guide. but thats it  :-\

The instructions are in the first two posts of this thread. If you are by any means not sure what you do, please try the original firmware images for Dragon Miner 1T, 1.5T and 2T (currently uploading) linked at the top of the thread.

I am sure we can help you with more specific questions when they pop up, maybe for the windows stuff anybody else can jump in. I heard good things abut  winscp https://winscp.net/eng/download.php (https://winscp.net/eng/download.php)

i already tried the ones from titan, all the same result..

ill read up on the instructions. will leave it alone if im not sure how to do it.



edit: and btw, ill let it run a month with your info on it if we can make it work. (yes i got free electricity ;) ) aint doing anything usefull anyway turned off...

Then your hardware is broken i guess. It does not have to be the blades, could also be the Raspberry Pi (mini computer) or the controller board that is broken. Heck, it could even be a broken PSU. I have also seen broken connectors that needed to be resoldered. I guess it would be best if you open up a new thread where we can discuss your hardware issues.

Sorry to bother you again with this non-so-relevant issue, I just found that I bought the non-PWM version of these fans, while the ones in your link have PWM.
Do you think that it will affect the noise? As far as you know, is there any kind of PWM support in the board, or they will just work the same? Or the support is not even needed?

ah well fuck it then, just gonna throw it out. would proberly be a waste of time and money to fix it

thanks tho, just had hopes for the firmware would solve it  ;D

I have an issue when setting up Stratum proxy - after all the steps and the last "shutdown -r now"
Cgminer fails to start up :

as you can see - it's stuck on ./superrun
if I manually run superrun.sh i get :

no key hook

which then never ends (and cgminer never starts)
running ./run.sh also never actually starts cgminer.

comment out  the options in /etc/rc.local.real - and we are back to normal mining.

is the 8 gb version ready ?

think its the one on page 1

man you are amazing!  :o :o :o :o :o

it does not work in a raspberry pi b+  ::) but in the 1 you get with it it does!

https://i.imgur.com/38d6Fbt.png
only running 2 asic the psu 1200W psu died ;/ so put a 600w in for now

Regards Roderick!

@biomatrix
sorry, i somehow missed your comment! Can you please PM me in case you still have this problem?

@yslyung
The 8 GB version is up for a couple of days now. In fact as some already noted, it will even work for 4 GB cards. If anyone needs the full 8 GB, the partition ca be expanded while the miner is running.

@roderick112
I tested it with a Pi 1 and Pi Zero and that worked. What happened when you tried in a B+? It should just work, but it might miss a kernel module for the controller board. If you really care, we can investigate and surely resolve this.

its not a problem was just testing ;) the miner really does work great now! thanks again for the proxy! helps alot

Regards Roderick!

Glad i could help! I think that's part of the game and gives new contacts all around the world for years now. Bitcoin is definitely not only about money, at least for me.

I was also amazed how much more stable and effective these devices can be, only with software tweaking.

Best wishes

P.S. Added the downloads for the original firmware files in the first post (all devices)

I will PM you about this later - I must be missing something - it's been a while since I setup a SP.

also, to anyone...

I'm new to this device.... what do these #'s mean.... and how do I resolve them?

TY got a nice OC with

volt 650
and clock 1100

Regards Roderick!

Looks like a sweet spot  ;)

There's one thing I don't fully understand:

On this firmware (like on the stock one), there's space for three pools.
I don't understand if the hash power is split between those pools or if the second and the third are used as fallback.

Does someone know that?

Fallback if you dont use stratum proxy from first to third one. Stratum proxy implements other strategies, too.

Thank you, got it!

Sorry to bother you again this issue, but the miner only has two fans. The other two are referred to the PSU?
Did you also replace them? Or did you made some mod to the case?

How do I check temperature? I see that voice on the log table, but it's empty

No need for excuses, glad when i can help. The controller board has sockets for up to three fans.

To use more than three fans, you have to use a splitter like this:
http://www.scan.co.uk/products/akasa-pwm-fan-splitter-supports-2-pwm-fans-from-a-single-motherboard-pwm-header
 (http://www.scan.co.uk/products/akasa-pwm-fan-splitter-supports-2-pwm-fans-from-a-single-motherboard-pwm-header)
As far as i can remember, the default view in "miner.php" does not display the temp correctly. You can switch to either 'Kano' or (afaik)  'Mobile' view.

Yes I found that, I was just asking "where" did you set up those fans?
I mean, I replaced the two that were already there with these new fans, but the other two? In series? Did you cut new holes?

About the temperature, still no way.
Even in the mobile view, the temperature column is just empty.
http://i64.tinypic.com/33u35fm.png

This also happened on the official firmware

I also tried to undervolting hoping to save some energy and, mainly, to keep temperatures a bit lower.
Do you think it might work? It says that the minimum voltage is 600 (which is? 6V?), I put 580 but I'm not sure it's applying.

I tried with 500 but only two of the four cards were running, so I guess it works, but if so, I don't understand that text.

Haha, now i got you. I fixed (with Sugru) the additional two fans on the back to assist the front ones with blowing hot air out of the case.

I understand, I will try something like that!

Any hint about the temperature not showing?

I have no idea. The temps are made available to cgminer via the controller board and this should work out of the box.
Which version of the miner do you own?

I've got a T1, do you mean that?
If you mean the cgminer software version, the one that's bundled into your firmwares, but I'm pretty sure that it also didn't work with the original one

can u make it api-allow W:127.0.0.1/W:192.168.1.0/24 port 4028 by default ?

i tried to write that in nano in run.sh file but after a reboot it overwrites it.

i think for newbies who are not familiar, take it slow n ask questions before doing anything else.

as for my 1.5ths i had to change the freq & voltages.

it'll be nice if we could compile list of freq & voltages ?

i flashed twice, latest version 1.2 when booted up i tried to change the ip on gui it did not respond well, hard reboot then ok.

after that when i was changing pools & username, same issue, have to hard reboot. a

it was using the webgui.

not sure about via ssh.

it'll be nice if u can make a menu in the webgui for the api allow & more options ? this screenshot is from coin craft desks.

https://i.imgur.com/mP8uerf.png

thx again for the effort op.

That's how it works and that keeps it simple. If you want the API to listen on extra networks, just add it to /var/config/extraopts. It will be kept. Please, please be aware that this is a  possible security issue.

I have no plans to extend the webgui, it really just adds complexity to the crappy parts of the original firmware interface.

A table with voltage and clock settings sounds like a good idea for everyone ☺

thx, will try it soon.

so just add below the volt & freq lines ?

api-allow W:127.0.0.1,W:192.168.1.0/24

Sorry for the late reply yslung,

--api-listen is already active by default, so it should be enough to add
--api-allow W:127.0.0.1,192.168.1.0/24 to the last parameter in the config file /var/config/extraopts and restart to activate on next startup.

https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FsPRw5gF.png&t=560&c=Mukg1lHlfHtAtQ

done that, tried n it works, but miner kinda acts weird using yr fw. maybe i couldn't find the correct volt & freq.

1.5 versions are very different from 1 or 2 thx versions.

must be the chip count. i'll mess with it more when i have time.

The chips don't make any difference, at least in my testing.

If you want to test the cgminer version that ships for your 1.5, i can look up the command to configure it for you. Also please disable the voltage and clock parameters in the config file.

Please, you should really not mess with voltage and clocks if you dont know what could work best and already have some experience.

Did the API settings work for you?

api works ;)

a little experience yes.

at default it did not work well. lower hashrates on miner side & also on pool side.

after small adjustments miner side improved but pool side showed lower hashrates. thats after at least 1 to 2 hrs of running.

if use stock fw, both miner & pool is much closer on the hashrates.

found that 800/800 works best so far.

Okay, one problem at a time - so API is a #CHECK#  :D

A clock of 800 is afaik the stock setting for the 1.5 version, so that fits. How much less hashing do you see in comparison to stock firmware?

yeps 800 is stock. it's about 200 ghs lower or more sometimes.

the hashrate builds up really slow at pool side but miner side is already mining at full speed.

ie : miner side says 1.5ths, pool side says 1.0 - 1.3 or even lower, sometimes after a long while abt 1 hr or so then it might get up to speed.

must be something somewhere. i also tried 850/850 , 900/850 & other numbers, but 800 & 850 works well & responsive to hashrates, i tweaked around with the voltages not much difference.

all of it were tested over a period of minimum 1 hour & in small increments.

Very weird indeed, 200 GHs is quite a bit and it should definitely settle after around 45 minutes.

Do you have the image of your Miner's SD Card available somewhere online? I want to check the cgminer version against the version i activated by default.

If you dont have an image or link, afaik you can also download the cgminer binary via webbrowser from the stock firmware by browsing to http://$IP_OF_YOUR_MINER/cgminer.

Here is the md5 sums of the different cgminer compilations:

I suggest you SSH into the miner with my firmware and check if switching to the stock cgminer cgminer3.9_1.5th version with the following command:

Please be aware that this version does not support voltage modifications via the option "--A1Vol", so you also need to change the /var/config/extraopts file to look like this:

let me dig it & upload, will pm you when ready.

thx again.

pm'ed. not sure if you have the same 1.5 ths version.

thx again for helping the community ;)

I have A1 2TH version from China, so I tried your A1 2TH firmware.
But it does not work. I can login via www, but miner is not hashing, in realtime stats Accepted 0, only Hardware errors.
Pools were set OK.
see http://i64.tinypic.com/34ijods.jpg

With original firmware (the same pools, same miner) it works without any problem.

Sorry, i can't see your pic. Is the URL correct?

I guess voltage settings don't work, please send me the output of the following commands via PM:
ps auxwww
bash /var/www/run.sh
cat /var/www/cgminer.log

You can also try to disable voltage settings yourself, instructions in one of my last posts to yslyung.

Original 2T Dragon firmware is only Chinese version (all button are also in Chinese). English version is available ?

I am providing these images just as reference for testing. Enhanced firmware is english and supports the 2T Miner.

Working well on my 1TH Dragon thanks :)  8)

Glad it works for you, have fun!

great firmware !! thx for the share..


btw.. i juz wanna ask u guys what PSU do u use? for the 2th version. i have a few of them without psu.. and i tried a few corsair and coolermaster 1000w PSU but cant power on. even burned(really burned.. with fire and all) 1 controller board and 1 psu in the process..

I used a XFX ATX ProSeries Black Edition 1250 in the last one, but can recommend any that are 80 PLUS Gold Certified.
Don't try to save a buck on the Power Supply.

i burned a corasir 1000w gold rm series if i remember correctly. they cost a bomb and i dont think i save a buck there though.. lol..

thx for the input.. ill try to find the same psu u have..

    I have several of theses 1th/s miners, one had its card wiped by 'accident'. I have been trying to install firmware onto new sd card, have flashed the card so many times it is reporting me to police! This 'easy' process has been sworn at, cursed and almost thrown in bin. Can I purchase the firmware already flashed to a sd card, or can I clone one of the other three (tried simple way- no play today).

   Please help, really, really doing head in now.

    Thank you in advance

Calm down.
What devices do you own exactly?
How do you wipe a card by accident?
Do the other miners still work?
What Operating System are you using?

when i download both mirrors the DHCP ones and i try to open them it just says file corrupted can you please upload another way to download? i need the DHCP becuase my network runs off 10.0.0 and my miner is 192.168.1 please and thank you i also have the dragonminer 1 t/h

The files are absolutely fine. How are you unpacking them?

• Please try with a recent version of Winrar (>= 5.x)
• Check the file SHA1 after download

SHAs - (see top of the thread):
SHA1(dragon_miner_mxnschmod_firmwarev1.2_20160108_ip254.rar)= 5de83e14ced8aa3326d2046a5d5b4a1b95d30a03
SHA1(dragon_miner_mxnschmod_firmwarev1.2_20160108_DHCP.rar)= 1b2fdf0e215c8b47e81925274cde4a8484640009

On Windows:

The following article will help you certainly:
https://support.microsoft.com/en-us/kb/889768

unpoacking with rar when its finished it just says file is corrupt ill download and try again with updated rar

still not working i just keep getting "file corrupt" when trying to extract from winrar

this is what i got for sha1sum

1b2fdf0e215c8b47e81925274cde4a8484640009 dragon_miner_mxnschmod_firmwarev1.2_20160108_dhcp.rar

also when typing the the DCHP IP in the address bar do i just put  http://$IP because when i do it just brings me to google.

i finally got everything to work but then i tried to set an ip and im unable to access it now how can i take out the IP i set in the settings

Can you access the Miner Webgui or Console?
The relevant config file is
You should see the Miners assigned IP in your Routers web interface.

Please tell me how to overclock and how to connect to the interface to make shh acceleration? Do you already have firmware that you can overclock it to do? And whether the firmware has enabled miners extonce subscribe ???

It's all explained in the first two posts. Please take your time and read them, it will work!

Hello,

I recently bought a Dragon Miner 1TH / s via ebay and use as a system this firmware here. It uses the CGMiner V3.9.0.1, but it is currently V4.9.2. How would I have to proceed to upgrade the cgminer without equal to destroy the whole firmware?

I am a Linux beginner, so please do it step by step. :)

Thanks and sorry for my english, it is from Google. :)

Is it working?? Then why mess with it??  ::)

You can't upgrade the cgminer version as it includes proprietary, binary drivers i did not bother reversing.

Hello, can you reupload DragonMiner 2T Original Firmware? Dropbox links doesn't work. Thanks

Hi,

i am use this firmware now one month. Now i want to start Mining at the Nicehash Mining Pool. I tried the whole day now to setup the miner into the XnSub mode.
I changed the this config into the     /opt/stratum-proxy/stratum-proxy.conf :

"pools" : [ {
    "name" : "Nicehash",
    "host" : "stratum+tcp://sha256.eu.nicehash.com:3334",
    "user" : "31yjiLRrgS8DusTz6YnZiwdoeXzkbqmK4m",
    "password" : "x",
    "enableExtranonceSubscribe" : true,
    "appendWorkerNames" : false,
    "workerNameSeparator" : ".",
    "useWorkerPassword" : false,
    "weight" : 9,
    "isEnabled": true
  }, {
    "name" : "Nicehash",
    "host" : "stratum+tcp://sha256.eu.nicehash.com:3334",
    "user" : "31yjiLRrgS8DusTz6YnZiwdoeXzkbqmK4m",
    "password" : "x",
    "enableExtranonceSubscribe" : true,
    "appendWorkerNames" : false,
    "workerNameSeparator" : ".",
    "useWorkerPassword" : false,
    "weight" : 9,
    "isEnabled": true
  }, { 
    "name" : "Antpool1",
    "host" : "stratum+tcp://stratum.antpool.com:443",
    "user" : "mxnsch.worker38",
    "password" : "x",
    "enableExtranonceSubscribe" : true,
    "appendWorkerNames" : false,
    "workerNameSeparator" : ".",
    "useWorkerPassword" : false,
    "weight" : 1,
    "isEnabled": true
  } ]


then i removed the hashes into the /etc/rc.local.real ...


I dont understand what you mean when you say:"    to apply these settings automatically. You can access the stratum proxy web interface at

http://192.168.1.254 OR via it's DHCP assigned address at http://$IP[/li]

3.) Last but not least, you must change your pool settings to point cgminer to the local stratum-proxy. The defaults are 127.0.0.1 and port 3333. Restart your Miner with
Code:

shutdown -r now

to apply these settings automatically.

You are DONE! ;-)
"...

Please Help  :)

It means you need to set the cgminer pool address to 127.0.0.1:3333 because that is where the hashes are sent to. In your case, that's a locally listening stratum-proxy. The local stratum-proxy re-routes depending on your config settings automatically. I hope that helps, i don't have any of these devices anymore.

Hello @mxnsch the links to the firmware are not working.

Hello,

first, thx for your work!

But i am a absolutly newbee in RasPi and have one question:

What should i do to change from fallover modus to balance?

ssh is working but then i dont know what i have to do.

THX
