is this the full source code?

NO!

There are missing some code.

Take a look at https://github.com/Zwilla/bmminer

ATM I merging it with cgminer 4.9.2

Stay tuned, do not try to compile atm. It will not work atm.

I will send an info when I´m ready with it and got it working on my S9 machine

No idea what you are going on about.
The code is simple to compile as it is in that git.

The main problem with it is exactly as I posted on my last post, it's the old cgminer 4.8.0 code.

[fubly]

That´s what I was doing at moment.

Switching from the old 4.8.0 to 4.9.2 nothing else.

What ever you guys find out is much appreciated. Fubly and Kano, keep us updated !!

I try to put S7 and S9 driver into one package.

I think that it will be possible to communicate from S7 controller board with S9 hashboard.

I got it up with a modified S7 driver and find out some stuff.

No I try to compile it and test it.

Some nearly identical functions (same name, but different params aso.)

Sitting here now since yesterday

now testing

Question:

Whats the best to find unused code, the file is now 2MB

Question:

Whats the best to find unused code, the file is now 2MB

The "strip" command? That's what I use on coin daemons after compiling. ie:

Code:

strip cgminer

[fubly]

other problems:

a combination of S7 and S9 is atm to complicated for me.

First run quit with segmentation fault.
Try now 2 runs

Also for this I have to put some #ifdef USE_BITMAIN_C5
into the code

Yes, but want to see what happened with the code, but thx.

Some parameters are corresponding with the external drivers of the board, and without the source for axi driver and fpga mem it is f....

I need a ready compiled version of about 1MB and then using stripe it will be about 512kb, but thats not my problem atm.

Do we all agree that Fubly looks like the one who is able at the moment to deliver the Cgminer 4.9.2 for the S9`s ?
If yes I will start to gather the BTC that people agreed to deliver for this Bounty.

I will hope that KANO will help cracking this issue and help FUBLY out with his programming if he gets into problem. This is a general problem that Bitmain made this BMminer and I think it will be in any ones interest that we show these guys at Bittmin that we do not accept this kind of behavior to the ecosystem of Bitcoin.
I hope that everyone is able to dig the axe down deep and start work together.
That said, all licenses has to be kept, so we need the license acceptance from -CK and KANO to be able to crack this nut?

I will ask philipma1957 to start up the ESCROW so BTC can be paid to FUBLY when firmware is delivered and approved.
If any one has other suggestions or corrections, please feel free to post.

Happy mining

build with cgminer 4.9.3 4.9.2 is ready for S7 and works well

########################
Now next level, S9

Case a) working on S7 Controller
Case b) working on S9 Controller
########################

./configure --bitmain   (mean S7)

./configure --bitmain_c5 (mean S9)

I will overwrite this to --bitmainS7 and --bitmainS9


p.s. Firmware S9 - I figured out an absolute easy trick* to flash the new version into S9

Just open upgrade - restore settings and use after this my script.

No one needs to reboot the machine, just restart cgminer / bmminer in respect for Kano and the other developers of cgminer I rename it to cgminer back!


<sub>*It cost me about two weeks of my life(**)


(**) and one S9 Miner</sub>

There is no such thing as cgminer 4.9.3 at this time. Please don't make people think that your resync creates a new official version.

Furthermore, the actual problems in the bitmain drivers go far deeper than just the core cgminer code and porting the rest of the code does not fix the driver itself.

[Xircom]

I think he made an Typo...or I hope he made a Typo 4.9.2 is the official version. If Fubly makes changes to the license of 4.9.2 he needs to publish the changes under the GPLv3 license and im pretty sure he will do so.
No more hiding shit, like Bitmain did it with BMMiner.

check!*
Typo error sorry!

[fubly]

compile ready (S7) cgminer with multi-version now with, which pool supports the

mining.multi_version, for testing?

Splitting now the option "--multi-version" into two vars, because bitmain is using this one value for two different options

hasta luego

[Xircom]

You need one to test your firmware on an S7 ?

[fvineyard]

I have been watching this thread with high hopes that a working updated firmware with version 4.9.2 of cgminer will surface.

Still committed to sending BTC for the reward in the amount I promised once a working version is available and tested on an S9.

Thanks!

Same here i stand by my offer.. Thanks so much guys.  To hell with bitmain for not releasing this.  Karma is a mysterious beast.  Looking forward to avalon miners to come soon:).  And since bitmain clearly marketed these r4 for home miners then what did i buy when i bought the s9.. And if its datacenter only will they be honoring a trade in.. Ill happily trade three r4 that dont sound like a fighter jet for my 2 s9.  Ive never seen a company bite its own foot so many times within such a short period of time.  uffff

Great that you guys stand by your donations. We are closer than ever to crack this nut. Get the word out that we need to gather as much BTC as possible for the Bounty.
