Antminer D3 Blissz firmware (10/12 v1.12 update)

[deezhere]

Hi All,

I wasn't aware of the GPL license, so I did some investigation last days. After reading the GPL licenses I can conclude that stangerm2 is right. So that means I do have to provide the modified sources as most of the current modifications are now build on top of a linked module in cgminer.

There are some consequences in releasing the source though:

- As far as I know, Bitmain is free to use these improvements in their current and their new products they will sell. I do hope they compensate these free goodies with a multi algorithm D3 firmware one day
- There will probably appear modified firmware binaries which can cause damaging your miners if the maker doesn't know what he's doing...
- I had plans to buy a S9 as there are a lot of requests and make a modified S9 version, but I might consider not to jump on that boat for now. (let's first see what will happen with the D3)

Legit alternatives instead of releasing the sourcecode

- I stop this project and take the binaries offline. I don't like this option, as the whole idea is to help improve the situations for the D3 owners.
- Temporary I take the binaries offline and I will write something from scratch / not linked to the sources of cgminer. This will take away the consequences, but a lot of time and effort (at least a month or two) will be put into something that will probably not lead to any improvements for you guys.

My proposal

- Although these consequences I will release source of a stable version (non BETA) that allow others to investigate the voltage / fan mods / fault check improvements I did. (devfee related code will be removed from the source). This allow others to look into the changes I did to make a binary for themselves without devfee.
BETA functionality will be left out of the source right now since it's not yet stable and will create dangerous situations when used in a wrong way. I might have to restrict the use of a BETA versions to a closed group instead of providing a public link to the BETA versions.

Happy mining

To add some encouragement to getting the source released, I'll be issuing a DMCA takedown to have bitcointalk remove this thread for copyright violations in 24 hours if the complete corresponding source code for all the distributed firmware binaries is not uploaded by then. I am a one of a number of cgminer copyright holders.

Blissz, I believe everyone here is greatful for the work and effort you've done to improve upon the D3. If you haven't already looked into github I would recommend you publish your source there. It's designed for just this purpose and makes it easy to commit new changes as you go. Thanks for the improvements and I hope this work continues into the future in a manner that is open and fair to all.

Blissz,
I think you should take the binaries offline and let these people fend for themselves. By using the scare tactics these people are only harming them selves. Did Bitmain share their software with the people? They used CGMiner software on D3 as well. Thank you for your wonderful work.

It's a shame it never got to a stable v2 for this... but I agree that Blissz should not give up the code. Why do any of this and not be compensated for the work. I thank him for what he did already and he should just let the rest use the D3 as the space heater it has become. The version I have is stable enough that I will keep it along with many others in this thread and Blissz will keep getting the devfee from us (even thou its only about $0.07 a day per unit). He would need at least 100 units running the devfee to make up having one unit to himself. again I say don't release it and just take it down and let these people who couldn't do it on their own to keep running the standard D3... it is barely making them any money at this point and they might just shut them off helping the rest of us with this FW.

Trust in the community. He will still make money (and with it released on github, probably more than he is currently in the long run). Remember we all know how to remove dev fees from Claymore and XMR-STAK, for example, yet a lot of us leave them in to support future dev.

That said, and as I said in the L3+ thread, I think locking the thread and removing the link to the firmware until the issue is resolved is the better approach, so that the support information in this thread is not lost for people already using it...

Hate to break it to a few people but there is already a no dev fee version of 1.12v floating around out there, and after testing it I can confirm it fixes the issues where the miner switches to dev fee then fails to connect properly back to the user pool.

Can you pls pm me the link?

Hi all,

As you might have noticed there is some discussion going on about the GPL license of the cgminer software that's used in my firmware.
I was not aware of this GPL license, but I am now, and I am quite sure the source should be published.
As I don't have enough time to do it now and want to do it properly I decided to temporary remove the download link to the modified firmware and lock the topic until this GPL issue is resolved. This will prevent that this topic get's locked / removed for ever and valuable information gets lost.
I hope I can resolve this issue as soon as possible. Sorry for the inconvenience,

ciao Blissz

ps. Please respect this and don't PM me for links to the firmware.
