Compatibility with Antminer U3

Nice!

Luke-Jr,

Tried 5.20 with Antminer U3 using latest CP210x driver and parms suggested in Readme.ASIC. Changed things around a bit and tried manual detect, but still could not get 5.20 to find U3 units. Any ideas? Thanks.

Same here, I have 2x U3.  I tried them on win7 and win8 machines,  using the cp210x drivers and with zadig winusb.  5.2 (or any other bfgminer version) wont detect them.
They are running on cgminer 4.8, but have to be hotplugged each time to start them up.

BFGminer has always been so much the better tool,  I hope that this can be worked out.

THANKS Luke-jr!

i tried to install bfgminer from git rep
no luck

git clone https://github.com/luke-jr/bfgminer.git
cd bfgminer
sudo pacman -S uthash
./autogen.sh
./configure
make install

i get error libbase58.so no found

is there any tutorial how to install this on arch linux ?

Just a guess as to your problem, but you probably need to do 'sudo make install' instead of just 'make install', as it's gonna install stuff (like the library reported as missisng) in system directories.

It also works to not 'make install' at all, and just run it from the build directory.

i am root

i do not need sodo

Hmmm, ok, that begs the question of why you used

sudo pacman -S uthash

but ok, I guess I misdiagnosed your problem then.

I am also experiencing issues with 5.2.0.  I followed the readme directions for the U3, using

Code:

-S antminer:all

and

Code:

--set antminer:voltage=x800 --set antminer:clock=x1286 --set antminer:timing=0.022421

bfg sees the U3, started mining at about 9GH/s, and decreased to 1GH/s over the course of a minute.  Anyone else had any luck with the U3?

I also tried 5.2.0 with my nanofury stick miners, been using 5.1.0 with them for a while now.  5.2.0 will not launch, however, it just hangs at:

Code:

[2015-06-08 08:53:05] Started bfgminer 5.2.0

5.1.0 continues to work with them.

Pretty sure this is the top FAQ in README. Did you try that already?

Never could get 5.10 to recognize U3 units. Same with 5.20. Using command line as suggested in README.ASIC:

bfgminer.exe -o stratum+tcp://stratum.mining.eligius.st:3334 -u x -p x --set-device OCL:binary=no -S antminer:all --set antminer:voltage=x800 --set antminer:clock=x1286 --set antminer:timing=0.022421

Using latest CP210x driver. U3 COM ports look OK in device manager, but 5.20 does not see them on startup. Manual input using 'M' and '+' does not work. Anyideas appreciated. Luke-Jr? Anybody? TIA.

What is the item I've bolded and underlined?  I didn't use that for 5.2.0 to see my U3.  But just seeing it isn't good enough, gotta figure out why it won't mine at more than 10% of it's ability.

I wish 5.2.0 would at least start with my stick miners, I'm at a loss why 5.1.0 works for them but not 5.2.0.

5.20 docs say this replaces the older "--no-opencl-binaries" command to ignore using CPU for mining.

[Mikestang]

Code:

"set-device" : [
"antminer:voltage=x830",
"antminer:clock=x982",
"antminer:timing=0.0054"

So the clock and voltage can be taken from the U3 user guide, however, it seems the leading 0 from the user guide needs to be an x, is this the case (frequency 250 has a value of 0982, so you input x982)?  If so, what about the frequency setting that begin with 1?  e.g. Frequency 243.73 has a value of 1306, what would this be in the config file for bfg?

How did you determine the timing setting?  I know the readme says "the number of nanoseconds each hash takes at the given configuration", but how do you determine that number?

5.20 docs say this replaces the older "--no-opencl-binaries" command to ignore using CPU for mining.

Missed that in the readme, but I never used the old command, either, and have never had bfg try to mine with my cpu...

[movellan]

I dont know exactly do you need to put x1306 or just 1306
you can try it

but timing..
i saw in antminer u3 pdf file that there are column for preferred timing


so i take in my case 0.54 and divided it with 100 ms
0.54/100 = 0.0054

and now its working with full speed

Can you post a full command line so I can get an idea where to start? TIA.

[Luke-Jr]

I wish 5.2.0 would at least start with my stick miners, I'm at a loss why 5.1.0 works for them but not 5.2.0.

Can you make a session with http://luke.dashjr.org/tmp/code/webisect/webisect.php and bisect the difference? Which stick miners?

[Luke-Jr]

5.20 docs say this replaces the older "--no-opencl-binaries" command to ignore using CPU for mining.

These just disable caching of GPU binaries.
It has nothing to do with CPU mining, and has no effect unless you explicitly enable GPU mining.

I'll give it a shot after lunch.  I am using Cryptorig HitchHikers, they use the nanofury chip.

In that case, can you also try putting the libhidapi-0.dll from 5.1.0 into the 5.2.0 directory?
The hidapi update in 5.2.0 was supposed to only fix bugs, but maybe it introduced new problems too..

Running through the WeBisect now, never done it before so I'm just clicking the skip button each time and letting it crank through...

I tried replacing libhidapi-0.dll from 5.1.0 and still no luck.  I'm also trying both 32 and 64-bit 5.2.0, just in case.

When I start both 5.1.0 and 5.2.0 each stick lights up when "[DATE TIME] Started bfgminer 5.X.0" appears in the command line window, then the lights go out on the sticks.  In 5.1.0 a few seconds pass, then they light up again and bfg launches.  In 5.2.0 they remain dark and the command line window sits at "Started" indefinitely (I've left it alone for over an hour, just to be sure).

Will post up again when webisect is done.

[Mikestang]

Here's the end of the bisect, not sure if I did it correctly or no, please let me know if this is what you were looking for (by the way the "16 revisions left... 4 steps" displayed on every screen of the bisect, I expected the numbers to change but they didn't):

Code:

garbage

[Luke-Jr]

You have to actually use it to expect any results... skipping is just a waste of time.
Test each build presented (they are all different) and determine if it's good or bad.
Use a new session name to start over.
