So what version of git?

After making sure you have an updated libblkmaker, you can tell autogen.sh to skip submodules with:
NOSUBMODULES=1 ./autogen.sh

What version of git itself? 1.7.10.4.

How do I make sure I have an updated libblmaker besides doing what I've done?

Hm, so pretty old. Maybe that's related.

git log inside the libblkmaker directory should show e9cd82be9352d502fce9df696a8933567e1e00a4 as the top commit.

You can use the git fetch command followed by git checkout v0.5.1 if it isn't.

Seemed to work. I was able to compile and run.

Testing the U3 is inconclusive however. It doesn't seem to run at the appropriate speed; running at 2 GH/s. Often with 80+% HW.

Are you using the antminer driver for it? -S antminer:/dev/ttyUSB0

Victory is mine! It works now. Seems to be hashing around 37 GH/s.

Seems it's not my 3G connection but something is really weird, when I arrived at the cabin bfg had crashed and said "No availiable pools" but during the better part of this week bfg had been unstable during the day, but stable during the nights.

I suspect some complex interaction between bfgminer and the 3G connection causes this. I guess the only proper thing to do is to fix a VPN so I can access the cabin from the city with a linux machine instead of my windows "oculus rift" gaming rig...

Oh, well, I'm going slush solo for now to see if that makes things stabler so expect a DDoS on slush any day now.

Any thoughts on why it's running slower than it should? I've read that the USB cable is crap, so I ordered a new A-B one. Will try testing with that.

The USB cables they come with are crap.  I have 3 U3s and threw all those cables out.  Are you running stock volt/freq (750/225)?  I only get about 40gh on mine with factory settings.  The factory power bricks are trash, too, you shouldn't overclock with them or they melt.  I run mine off an atx psu with molex 4-pin to barrel plug connectors.  I run at 785mv and 244mhz for 58gh @ <0.8% error.  You can play around and see how yours responds, max volt is 850, but 800 is considered high; max freq is 250.

Definitely set voltage and frequency. I have no idea what the defaults are.

The USB cables they come with are crap.  I have 3 U3s and threw all those cables out.  Are you running stock volt/freq (750/225)?  I only get about 40gh on mine with factory settings.  The factory power bricks are trash, too, you shouldn't overclock with them or they melt.  I run mine off an atx psu with molex 4-pin to barrel plug connectors.  I run at 785mv and 244mhz for 58gh @ <0.8% error.  You can play around and see how yours responds, max volt is 850, but 800 is considered high; max freq is 250.

What commands are you using in BFG to set the stock and freq? Also, what type of PSU are you using exactly?

I actually use a different program for my U3s, but I use bfg for my nanofuries.  Luke should be able to tell you the commands to set volt and freq, or they may be in the readme.  I have a 850w psu for my S1, and my 3 U3s share it, they use about 60w each.

[Luke-Jr]

I'll try to document U3 stuff in README.ASIC before 5.2...

Using BFG for my nanofurry's and my BFL single. Have a friend sending me an Antminer U3 to ad to my "junk" miner collections. Is it officially supported now, and if so in what version?

Hey guys,

i have the latest bfgminer version on my raspbian. But i have no menu or something like the older versions.

here u can see how it looks:

it's working but it looks wrong

Hi, i am having troubles with my alcheminer scrypt miner when using bfgminer as a getwork to stratum proxy (also as a stratum to stratum proxy). My problem is that bfgminer send difficulty 0 to my miner.
Is there a way to fix it? Is the fault in my miner or is BFGminer sending difficulty in some strange way?

Difficulty >0 would be extremely hard for scrypt.
--set pxy:diff=1 should work, if you want to try it though.

It looks to me like ncurses is not working or was not compiled with the build.

I tried a bit more. On litecoinpool it works and the diff is sent correctly to the getwork miners. But i need to be able to set difficulty below one since that equals 65536 which is a bit high.
--set pxy:diff= works and it sets the diff correctly i.e --set pxy:diff=8192 gives diffculty 8192 (in scrypt) to the miners but i wont work on vardiff.
Ghash.io doesnt transmit the difficulty to the getwork miners so i need to set it manually but it doesnt work very well.

I have the python source code for the miner. Would it be possible to convert and add it to bfgminer? It uses serial communication to the chips.

Thanks for the reply.
