Any update on overclocking the Antminer U1? 

Just going to need time. It's not difficult, just a lot on my plate (I have a day job and another side job outside of all this Bitcoin bidness  )

I also want to try to figure out how to properly ID these buggers so I can tell them from BEs.

The good news is I got in touch with Bitmaintech and they are providing me with info to keep development going so that should be a great help.

Also interested in this.  Currently running my BEs and U1s on separate machines to avoid the conflict and get the best performance from each (U1s running at about 1.9 Gh/s each using the '0981' freq setting). Of course, if I sell my BEs to a suck, er, another miner and replace them with all U1s, then it's a moot point

Do you have to start the U1s one at a time with BFGMiner like I have to do with the ANT branch of cgminer (on a Win7 box)? Sure would be nice if they all just started like the BEs do!

The ANTminers act just like BEs when running nwoolls BFG390, so just have them plugged in and start BFG

For some reason I am unable to make the antminer version of bfgminer, I get this on "make":

...

Also from looking at your driver code there does not appear to be any way to overclock the USBs?

Make sure you run autogen.sh first so that libblkmaker is pulled down from Git.

There's no options support at all right now. Still getting it stable and working but the options shouldn't be hard.

Ok, got it compiled, bfgminer runs, but devices are running way slow (ie 500-900MH/s)

Also they show as ICA0, ICA1, etc..not as "ANT 0, ANT 1" etc...


EDIT: needed to add commend "-S antminer:all" instead of just "-S all"

[nwoolls]

You have to run bfgminer with the -S antminer argument (e.g. -S antminer:all).

Also, make sure after cloning the repository you checked out the branch feature/antminer-u1-support.

You can check to see if bfgminer is compiled with AntMiner support by running bfgminer --help and looking at the list of drivers at the top.

Thanks working now.

Would overclocking them just involve tweaking this line in the driver?

Code:

#define ANTMINER_HASH_TIME 0.0000000029761

Or is there more to it than that?

No there is more to it than that. There are commands that must be sent to the device.

[dave111223]

Oh well, thanks for the driver, it's already running more reliably than cgminer.  Got it running 27 on a Pi at the moment, cgminer would only handle about 20 before it crapped out.  Will push it to the max later, see how many I can hook up.

Wish I knew how to code C so that i could help out with the overclocking.

That's interesting, somehow bfgminer 3.9.0 or btcguild pool switched from worker's diff 8 to diff 16 with olddifficulty rejection message
...

Expected. There is a workaround for very old (no longer a problem?) pools that treated difficulty wrong. This results in invalid shares being submitted unnecessarily, but is otherwise harmless.

Seems strange, because bfgminer never lowers the diff, even if it is set to lower number in worker's property while mining. Can bfgminer only get worker difficulty correctly only at start?

It does, just not right away.
Essentially it works as lowest-of(job-difficulty, current-difficulty)

So (without understanding how exactly mining works) there is nothing to worry about this on-the-fly difficulty changing?

Having a weird problem.

On one Raspberry i've got about 35 antminters hooked up and running find.

On another Raspberry I cannot get it to detect any devices.  Using -S antminer:all or -S all just saying:

Code:

NO DEVICES FOUND: Press 'M' and '+' to add

I installed bfgminer the exact same way on both raspberries.

Try swapping the sd cards

[dave111223]

Formatted the SDCard and USB drive and now working correctly.  Corrupted filesystem seems to have been the problem.

I have 3 rPi in my system

Just one of them, occasionally corrupts the sd card when shutting down, the other 2 have behaved well up to now.
Its always worth having 1 or 2 spare cards formatted and ready to go.

My 3 rPi corrupted the SDCards so often (almost daily) that i had to switch them all to using USB thumbdrives from the OS; SDcard only for boot sector.  After that they almost never corrupt (except for today  )

When running a windows terminal, how do you configure/disable the colors of the terminal?

I want to remove of the red background on the top line, remove the blue background on the second line, and change the top line font color to the default light-grey.

Basically I want the entire window to be a uniform black background and light grey text.

Not supported at this time.
What is the use case?

oh, it's just that I'm running bfgminer on my windows machine and I don't like the way it looks and wanted to change it.

maybe that's a config option that can be added in the future then... thanks for the quick reply.

cgminer still looks like shit, if you prefer that look.

nwoolls,

Definitely appreciate your work on this, but I'm missing something.  I've git cloned and git checkout'd your code and driver-antminer.c shows up, but I don't think it's getting compiled in.  I tried the "--enable-antminer" and it produced the correct object file, but when I run "bfgminer --help" the antminer is not shown in the list of drivers supported and of course my ants are not recognized (no devices, same as others in this thread are getting).  And I'm invoking with -S antminer:all...

I know I must be missing something basic, but haven't been able to track it down - help?

Thanks!

Any chance of a Windows binary with ANT support?  Screenshot is very nice and all, but I'm loathed to run cg (with all the zdiag and WinUSB bollocks fecking up the USB drivers) to get these things working.

https://www.dropbox.com/s/z29x4n6ng510joi/bfgminer-npw-antminer.7z

If it breaks I didn't do it 

Code:

bfgminer -S antminer:all

Note that, like the Bitmaintech cgminer build, this won't play nice with Block Erupters for now (unless you manually specify the driver for each devices with -S antminer and -S erupter).

Thank you!

antminer drivers are tied to the icarus drivers, so you don't need to enable the antminer drivers separately.

Just do ./configure  no need to add any enable options.

(If you manually disable icarus driver this would also disable antminer, so don't do that)
