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

[cero9]

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?

[mxnsch]

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.



thx again for the effort op.

[mxnsch]

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

[mxnsch]

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.

[yslyung]

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.

[mxnsch]

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?

[yslyung]

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.

[mxnsch]

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

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.

[mxnsch]

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:

Code:

c3763e066ad2014133e4b06f513bfc5d  cgminer3.9_1.5th
78196d5bc6eb356f69d5a05ead431fad  cgminer3.9_1th
c5cc325b87907580faa036b63a10397e  cgminer3.9_2th

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:

Code:

cp -f /var/config/cgminer3.9_1.5th /var/www/cgminer

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:

Code:

# Those settings are read and applied additionally
# Do not change if you have to ask what this means
#
# max overclock and voltage
# a1vol=890
# a1clock=1100
#
# max underclock and voltage
# a1vol=600
# a1clock=700
#
#export a1vol=600
export a1clock=800
export extraopts="--A1Pll1 ${a1clock} --A1Pll2 ${a1clock} --A1Pll3 ${a1clock} --A1Pll4 ${a1clock} --A1Pll5 ${a1clock} --A1Pll6 ${a1clock} --A1Pll7 ${a1clock} --A1Pll8 ${a1clock}"

[yslyung]

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

thx again.

[yslyung]

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

thx again for helping the community

[charles2k]

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.

[mxnsch]

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

• 1T Dragon Miner DragonMiner1T_OriginalFirmware
• 1.5T Dragon Miner DragonMiner1.5T_OriginalFirmware
• 2T Dragon Miner DragonMiner2T_OriginalFirmware

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

[mxnsch]

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
