Topic: Bitmain AntMiner U1 Tips & Tricks - page 35. (Read 106330 times)

I made a few more changes to my branch of the bitmaintech branch of cgminer.  Probably most important is that I removed the need for the bmsc-options command line directive and allow overclocking settings to be stored in the config file.  My config file with a mild overclock looks like

Which I think is a lot better.  I invoke cgminer with the batch file
I am running 7 U1's in a cheap 6 dollar Chinese 10 port hub powered by a 5 amp power supply with this and it runs great.

As usual, you can get my latest code with

git clone https://github.com/fractalbc/cgminer.git

followed by the usual sets.

how many do you run like this?

Interesting evening getting these working on my pi.

Il detail my steps incase anyone is stuck.

Firstly, I used cgminer.config to save having my pool details in the launch string, to create this, type the following

cd
sudo nano cgminer.conf
///Paste the below info, editing the pool details\\\
{
"pools" : [
        {
                "url" : "PoolAddress:Port",
                "user" : "UserName.WorkerName",
                "pass" : "Password"
        }
]
,
   "api-listen" : true,
   "api-port" : "4028",
   "expiry" : "120",
   "failover-only" : true,
   "log" : "5",
   "no-pool-disable" : true,
   "queue" : "2",
   "scan-time" : "60",
   "worktime" : true,
   "shares" : "0",
   "kernel-path" : "/usr/local/bin",
   "api-allow" : "0/0",
}
///Press ctrl+x to exit, y to save the file and then the Enter key to confirm...\\\

Now, its time to tackle cgminer itself.....

sudo apt-get install autoconf
git pull https://github.com/bitmaintech/cgminer
wget http://ck.kolivas.org/apps/cgminer/3.8/cgminer-3.8.5.tar.bz2
tar xvf cgminer-3.8.5.tar.bz2
mv ./cgminer-3.8.5/configure ./cgminer/configure
///This is done because the next command kept moaning that there was no configure directory, so I gave it one....\\\
./autogen.sh
This takes a long time....
./configure --enable-bmsc
This also takes a long time....
make-j

Next, is that all important file change to stop cgminer crashing as discussed on page 2 of this topic, but basically...

cd
cd cgminer
sudo nano  driver-bmsc.c
///Press ctrl+w then paste this...\\\
memcpy((char *)&nonce, nonce_bin, sizeof(nonce_bin));
///Remove that and replace with this...\\\
memcpy((char *)&nonce, nonce_bin, sizeof(nonce));
///Press ctrl+x to exit, y to save the file and then the Enter key to confirm...\\\

To test, run the following...

sudo ./cgminer/cgminer --config /home/pi/cgminer.conf --bmsc-options 115200:20

You should see CGminer start mining, if you do, press CTRL+c to exit.

Then, I launch with the following line on bootup by typing...
sudo nano /etc/rc.local
Paste the line below befpore the Exit 0 line in there...
nohup ./cgminer/cgminer --config /home/pi/cgminer.conf --bmsc-options 115200:20


This was (as im sure people realise) based heavily off of the adafruit PiMiner tutorial, but im putting it here in one single place so anyone such as me finds it easier to start mining with their Antminers.

Okay   anyone get windows vista to run the custom cgminer..  I have been selling sticks on ebay and one buyer has vista.    do I just set him up like it is windows 7?

My settings in Win7 sp1 64bit: cgminer.exe --bmsc-options 115200:20 --bmsc-freq  0981



BE's mining with Overclocked Ants 

Im using 0981 and a Artic usb cooling fan and they are getting between 1.8 - 2.1GH/s

does anyone know what a safe overclock is on theses and do they need extra cooling?

I too am running my miners of an externally powered USB hub, but what I'm most curious about is how you built the AntGen1/AntMiner cgminer repo on OSX. I've been hit with a dozen errors that I simply can't troubleshoot because a dozen more open up after each one I squash.

Could you please provide some additional information on your cgminer make, setup, and run procedures for OSX? I would be very grateful.

Aha, there's your poblem - you're trying to use the linux executable rather than compiling your own.  The linux executable only runs on x86 or x86-64 processors, which the RaspberryPI does not have, even though it is linux.  You need to "git clone" the source as per earlier instructions in this threat, then make the change suggested (i.e. delete the "_bin" portion), and then "./configure --enable-bmsc" and then "make" and "make install" then you should be good to go with your very own "custom" executable for your PI.

I have to do that as well on a 7 port Antec USB hub with six, fully over-clocked, U1s. In fact, I felt like I was trying to save Apollo 13--I had to figure out which U1s had to go in which slots in which order to keep cgminer from going wonky on me.

In theory, and we'll need our resident Big Toe Twib2 to confirm, once cg(bfg?)miner starts supporting the U1, that should go away.

Thanks very much... I'll give it a shot now (it'll probably be this time tomorrow before the RPI finishes building!)

/edit
Success!!! Thanks for all of the help!

On a Win7 machine, I leave one U1 plugged into the powered usb-2 hub, start cgminer (I use a freq code of 0981 with a re-purposed cpu fan blowing on them), wait until the first U1 is running, then plug in the next, wait until it's running, repeat until my 4 are all in. Sometimes I've had to reload the usb driver for one of the U1s, but not always.  It's been reasonably stable of the last couple of days (though the machine rebooted once for updates, and last night the machine mysteriously crashed - can't say it's related to the U1s). The 4 U1s run about as fast as my 22 BEs (running on a separate machine because of the compatibility issues).  

I very much agree that the U1 offers a much better price/performance than the BE or the furys.  Now we just need to mature the software driving them (ideally to allow them to play nice with my BEs!)

Hey thx 4 your help, but I have a problem I didn't find driver-bmsc.c on my SD Card. Do I have to configure it directly in Minepeon? Or do I have to make the file on the SD by myself? Would be awesome if somebody can help.
Thank you in advance
Greetings

Good idea. Thanks.
That speeds the process up.

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.

As far as I know, that's the only solution... My way around it is to disconnect the USB hub, plug 1 antminer into the PC and start cgminer, then plug in the USB hub and wait for it to pick up the devices, then unplug the device from your PC and plug it into the hub... Bit of a PITA, but not much effort really. Hopefully a proper fix will be on the way soon.

I've done a crash course in cgmier and got my U1 miners working as expected, but do the U1 miners have to be plugged in manually every time cgminer restarts?

On Windows 7, starting cgminer with all the U1's connected causes a "Program not responding" state.
Unplugging them all, re starting cgminer, and pluging them all in one by one seems to be the only solution.
Is there a work around for this problem?

ppl, please help!

I run 4xAntminer u1 directly from my PC-Ports. I get lots of HW on default  settings:

I use custom Anminer -cgminer version.
First i  start batch file with:
After  all frequencies are set, the cmd-window crashes, but it doesnt matter.

Then i start  another batch. file with:
.
And the software starts mining.
But still the HW rate is way to high, and the pool seems not to see my full hash rate...
What do i do wrong? Maybe not enough power for 4 Miners and i need separate USB3.0 hub? ( my PC has 600Watt power supply).
I am new  to BTC mining, need help.

 I originally put -j 6 in there (which I think iluvpcs carried over too) just for my system - it uses all six processors when compiling.  Just use the correct number of cores for your system, or leave it off; it's not that much slower on such a small program.  I'm just in the habit of using all cores especially for the xxxcoin-qt programs that take an appreciable time to compile.



You probably need to edit the driver file.  In the diff output given you can see that there is only one small thing to change.  I think it was to find the matching line and delete "_bin" but you should make sure.  Anyway, to answer your other question, no, a cut and paste of that whole change posted won't work - you either need to run it through diff or just do the small edit by hand to make it match the updated line.

@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?...
