Antminer D3 firmware testing

[slv1221]

Who can tell please, how i can open bitmain firmware and some change in there ?
Some script for ubuntu or what ? Help please

tar xvf to extract the tar
then use 7z to extract the .SD file
you should get a .cpio file use
cpio -idv < /tmp/object.cpio
to extract the cpio file
make sure you are root when you extract the cpio file

Is it possible to solo-mine to a wallet with this firmware or do you know of any way to do so with the D3? Thanks 

[ChilliWinter]

you may try ssh it too
quick way to go in if you don't mind changing a lot

which parameters I have to choose to login?
Port?

[Edrick123]

For the voltage can I do it for individual board with tons of hw? Or the voltage setting is for all 3 board?

Hi, is possible to pass the voltage settings using ssh commands instead of using web interface?

Cheers W_M

ssh is tcp 22
user: root
pass: admin

Do it allow to change the original fans?

Cause I tried change them (Noctua nf-f12) and the machine didn't start at all  :-(

I didnt like of the Blizz one that it disconnect from the pool i'm minning to make the dev job, and that's is heavy penaltied there.

Thanks.

Yes you can set the fan slope by increasing or decreasing the max fan temp and min fan temp
Edit I missed this as well sorry I'm at work and reading fast.
I'll add support for 0 rpm fans in the next release

Kinda if you modify the file /config/cgminer.conf then restart cgminer you should be good

Try all permutations of frequency and voltage

Edit I misread this. Yes I'm working on individual board voltage I just need some modivation to finish. No eta yet

Hi, sorry to disturb you again, is necessary to recompile CGMiner to pass voltage controls?

Cheers W_M

listed out the changes now for you.
its literally just custom voltage and slowing the fans so far

I have not tried this your FW, could your FW reboot if there is a "xxxx" error on the board? or MH / S (RT) reduced? If so, then too good.
If you develop it well, even if you charge a fee (just get one, I'm willing to support it). Do not like Blissz, charge life d3, I hate it

from the code it looks like you need to if you look in the dash_init() in driver_btm_DASH.c the voltage with the stock FW is never set.

haven't implemented this yet maybe some time soon

I am moving to San Diego  so my development may be limited in the near future

Hello.. really strange problem.. Compile cgminer from sources..
All ok.. Its works, but when im get API call cgminer crash!
with

cgminer:
*** buffer overflow detected ***

Where is the problem?

[sanitariu]

Anyone have fix for high rpm fans when there is no internet or connection to pool is lost ?
All the rest is working good.
Maybe and separate option for each board to control voltage and some kind of high temp protection.
So if it goes over 100% just to stop cgminer.

Wish I had found this thread earlier, reading through now... BUT this particular thing I know the answer to.
On all the newer bitmain stuff you can't mine directly to a wallet, older sha-256 you can. I'm not 100% sure on s9's since I
do not have one. That being said: --disable-libcurl <-- there is the issue. You can compile with disabling libcurl, but you get
errors if you leave it enabled. (I'm trying to look and see what the deal is there.. but libcurl is what is needed for it to accept
getwork and GBT which is needed if it directly connects to a wallet.)

I've been trying something on my own, but would have saved myself ages if I had found this thread earlier. hehe.
If I sort out what the deal is with libcurl I'll be sure to post something about it. I'm cross compiling as well and really
going through each problem by hand having never cross compiled anything before was...  screamy-stabby-feeling.
I should search through topics more often. Hahaha.. but I have to admit I've learned alot so might have been worth it.

Question what did I do wrong here....

Nevermind .. think I got it.. seems (and if I am wrong please let me know) that I need to open the .SD file AS a cpio file and it extracts everything. not sure if there would be some header issues?? when putting it back together or not.

pre-coffee me here, but you know what? I never thought of that. "technically" the ability to pass voltage is "built in", so you "should" be able to do it with just the conf file. - I do not know this 100% as I have not tested it.

beem working on so many other things I have not looked into this but at a guess notice that there is a cgminer-api binary in the same folder as cgminer on the machine. so I'm betting it has to do with that.. will get around to digging at it later if no one else does though it will be a whiiiiiile for me.
