1  Bitcoin / Mining support / Re: Bitmain AntMiner U1 Tips & Tricks on: January 11, 2014, 12:52:18 AM
Thank you nwoolls for bfgminer support.
Thank you MineForeman for MinePeon.
Both work together like a charm on RPi.
Thanks to this post on MinePeon forum. http://minepeon.com/forums/viewtopic.php?f=4&t=1213&start=30

IMO bfgminer works better than cgminer, I've been running it for 12h so far no crashes 27 rejects and only 1 HW error. Wasn't the case with cgminer.

Cross posting this since there's some discussion going here as well:

If anyone feels like testing out the latest AntMiner U1 code, it now supports both over-clocking and running side-by-side with Block Erupters.

Code:
git clone -b feature\/antminer-u1-support https://github.com/nwoolls/bfgminer.git bfgminer-npw
cd bfgminer-npw
./autogen.sh
./configure
make

Make sure you see a driver-antminer.c before compiling and a driver-antminer.o after.

Probing is done similarly to the Block Erupter:

Code:
bfgminer -S antminer:all -S erupter:all

And you can overclock using --set-device:

Code:
bfgminer --set-device antminer:freq=4F02

Windows binaries:

Tested on Windows, OS X, and Raspberry Pi (using MinePeon)

It Works For Me™



Nice this works with your MultiMiner too, just copied zip files contents to the one in MultiMiner. Nice GUI but I like the terminal look in bfgminer. I'll have to try to set up Minepeon on my RPi.
Thanks

Finally got RaspPi and AntMinerU1 working. This saved me a headache. I had enough trouble with other things. The biggest was every time I ran cgminer -n the device would come up ERR-3. I am not running in root, so my user name had to be part of sudo and plugdev groups and then sudo cgminer -n. Works great on PiBang.
I got 1 issue left, it gets HW errors in cgminer; even in WIN7. Its a VERY low percentage. What is considered too many and I should be concerned?

That success was short lived. Keeps crashing. I think its the USB thing on RPI. Don't feel like wasting another day fixing just yet. Think I'll wait for bfgminer update then try again.

I've had my Pi totally lock up a couple of times when I left cgminer running while connected to it via SSH - it happened roughly 1 hour after starting it each time.
I set up a simple script in etc/init.d so that it runs on startup and that seems to work OK overnight without any problems, so not too sure what's going on there... I guess that's a problem for another day, though!

I had the same thing happen in SSH, then booted normally and ran from terminal but still crash. I'm thinking its my hub I'm using, originally when plugging in Ant the Pi would reset and boot again. Now I'm wondering if there is a better board than RaspPi to run on.

@fasmax

Sorry, I'm not entirely clear on what I need to do with the driver file... I take it you mean driver-bmsc.c?
Do I need to just paste the code from post #37 into that, or does it need to go somewhere in particular... Do I need to recompile after doing that?...

Yes You need to change the driver-bmsc.c file.

Change this line
memcpy((char *)&nonce, nonce_bin, sizeof(nonce_bin));
to
memcpy((char *)&nonce, nonce_bin, sizeof(nonce));

Then build.

Been mining for about a month started with Litecoin and AMD6870, then added and old AMD4770. Then the pool I was in got too many Ghashers so it wasnt good for me and my low setup.
Yesterday got 1 Antminer U1 setup and now working in Bitcoin, probably get more when I can afford.
Now if I can only get the Antminer on my Raspberry PI.

Newbie myself but I just got an Antminer U1 off ebay for $90 it is running on Win7 at 1.6G as advertised. In BTCGuild pool, I want to get it set up on my RaspPI $35 and a powered USB hub $15.
Total invest $140 if I set and forget it(not really) I should be able to make some coin. I'm not expecting to quit my day job. Power usage is minimal. It mines NameCoin while mining BitCoin.
I was running my pc with a AMD6870 getting Litecoin but it is a power hog, plus you kill your video card.

Just being an optimistic Newbie/hobbist
