[Enhanced Firmware Mod] Dragon Bitcoin Miner ALL (1T,1.5T,2T) versions

[mxnsch]

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)

awesome ! some screenies will be nice !

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



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

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):

Hashrate (30min avg)	Voltage	Watt usage	Clock	HWErr
1,127,458.58	890mV	1240W	1100	10%
715,774.55	600mV	750W	700	0%

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!

[yslyung]

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?)
