Raspberry Pi Running Antminer U1

[tunaphish1]

Hi I am new to the forum.  I have a question regarding piminer with BEs and Antminer.  If two instances of CGminer need to be running to support BEs and Antminers on the same hub, will piminer be able to display information from both instances of CGminer?  Sorry if the question sounds confusing.  Thank you in advance!

hmmm, yes they do get v warm when running at correct speed.

Does the Antminer run ok on say a normal windows pc? Or do you have a 2nd unit to test to see if its duff or not?

Other than that i would unplug all devices, completely turn off, then back on insert only the antminer and try.

if not go back though and perhaps re-do all steps. (Should be fairly quick at doing these by now! i know i am..lol)

just one more thing to check, there may be somthing wrong in your start line! somthing as simple as a space in the wrong place, or only 1 - instead of 2 --. if the freq and bauds are not sent correctly then i think it goes to a low default setting.

sudo ./cgminer.exe --bmsc-options 115200:20 -o stratum.bitcoin.cz:3333 -u oldiesel.worker1 -p x --bmsc-freq 0981

drop the .exe! (this is only for windows)

You don't make this up! ;-(

I ran the install again, in the right and complete order.
still low speeds,...damn.
Checking the USB hub powersupply,......Guess what,....DEAD!!
So after all the supply of the PI was feeding it.

Hooked on a universal net adapter ,both Ants running now on speed.

How many U1 that PI can handle?

I'm still not able to get past this line...
cd ./cgminer
./cgminer --bmsc-options 115200:20 -o mint.bitminter.com:3333 -u bitcoinco_demo -p x--bmsc-freq 0781

Now I get:
Unexpected extra commandline arguments
Segmentation fault

Also: do I add the '--usb :1' command like this:
./cgminer --bmsc-options 115200:20 -o mint.bitminter.com:3333 -u bitcoinco_demo -p x--bmsc-freq 0781 --usb :1

I'm getting the same error message on my pi - did you resolve??

I assume you have but I'll just make sure......... You have changed the relevant fields to suit your mining pool and your workers account + password? (in bold text below)

yes - i'm now getting it to boot up in cg miner ok, but saying usb init, open device failed, err -3, you don't have privilege to access...

edit.. i just went back to adafruit instruction as I was using BE before ant miner.. states that icarus code is for BE only.. can anyone confirm what should be here or shall i just remove?

        {
                "url" : "PoolAddress:Port",

greenemeso:-
For ant miners you should --enable-bmsc during the cgminer setup

the cgminer.conf file you have there should only be used for 3.1.1 on BE's (so leave it alone as 3.8.5 will not look for it)

also when you run do
sudo ./cgminer etc........

this should fix the privalidge error.

Olddiesel:-
Good job figuring out the power supply! things like that you always assume are ok!

Mrclown:-
Not a clue how many it can handle, buy 100 plug em in and let us know!..lol

[greenemso]

thanks Sweaving - i have followed the instructions as per previous posts
-- enabl-bmsc
then..
made

but after made just get error which says something like - you don't have permission to access this file

I can still start the miner but it doesn't recognise as before..

any ideas?

Did you miss the Sudo?..lol

[greenemso]

yep!  

another problem though  .. running through console on iPad.. when it closes so does cg miner!??

Hi,
What terminal/SSH app are you using on iPad?

Question
What success are people having.
Are you generating any bitcoins?
How much if you don't mind saying.
Thanks

So far, since they arrived around 2 weeks ago, I've earned 0.01202089 BTC with Slush's Pool having overclocked my 3 Antminer U1s to 2.2GH/s after a few days testing at 1.6 and 2 GH/s.
Using preev.com BTC/USD/GBP currency exchange calculator, I've earnt almost £6 at the current exchange rate. While it's nothing huge, it's decent and more than covers energy cost. I am yet to see whether they'll break even though!!

Hi Sweaving

I'm having a few issues with CG Miner going offline after a few hours - I keep rebooting and its all looking fine, but same thing keeps happening - any ideas? 

thanks

Business of the century

One antminer costs £59.9 + posting at cryptoware (unfortunatelly its sold out now)

[LuckyDime]

"If you are using a Raspberry Pi do the following:

sudo nano /boot/cmdline.txt

Add the following code at the end of the first line (on the same line as the other text)

slub_debug=FP"

[greenemso]

Hi Lucky, yes I'm running on pi - I did enter that and x and y'ed it - but when I have checked back on just now the command had gone back to original (without slub_debug).. i guess I have to add each time?!

thanks

All,
For referance, i had been running 3 Ants at 2.0gh with a fan, they seem to be ticking along nicely, with no down time and maybe around 0.02% share reject rate. so im a happy bunny. just had my first payout from Slush Pool 0.01BTC!

when you say going offline do you mean internet connection? or cgminer? or the pi just shuts off?

did the "debug" work?

when you save do Ctrl +X then enter to confirm the overwrite, it should be perminant!


PS if ive helped any1 and they want to make a small donation (LOL)!

Hey Sweaving, What is your next plan with your antminers? Are you going to keep at mining bitcoin or try something else?  I'm looking for inspiration really as I have a couple of antminer which are mining as we speak in slush until i get my 0.01 min payout.  I'm a little unsure whether I should get another antminer or just sell them once I've got my 0.01?  I only originally got them so I could learn a little about how mining works. They aren't costing me anything to run as electricity is included in my rent.  Are you planning on adding to your miners? Also, the mining difficulty is going to be ridiculous for people with only a few gh/s like us soon won't it?
