OLD: BFGMiner 3.10.0: modular ASIC+FPGA, GBT+Strtm, RPC, Mac/Lnx/W64, AntU1, DRB

[vulgartrendkill]

bfgminer 3.1.4 changed the default storage location for the bfgminer.conf file.

Err, no it didn't... O.o;;

my mac stores it in ~/.bfgminer/bfgminer.conf

used to be stored in ~/bfgminer.conf

O.o
{facepalm}

Must be a homebrew thing... It's always been ~/.bfgminer/bfgminer.conf officially.

So, I've amended the bfgminer.conf file removing the pools I don't want and saved it using all files and the .conf extension and yet the pool still appears when I restart bfg.

do I just have to amend each time i have to restart bfg?

It sounds like you're somehow starting bfg with these pools on the commandline.
The config file won't remove pools you put on the commandline.

So if I edit my .bat file removing the pools I have entered there that should solve the problem?

Do I use the conf file OR  the .bat file or do I need both?

Sorry, still a bit of a newbie when it comes to all this.

Remove the --temp-cutoff commandline or "temp-cutoff" from your config file.

thx I have erased the line with --temp-cutoff from config

now

Code:

BFL 1: 65.0C 

what is a good target temp for BFL LS?
is 65 - 67 ok?
TIA

BFL devices don't currently support temp-target and ignore it.
You can set a temp-cutoff (85 seems like a good value), but note BFGMiner has to shut it off entirely when it goes above it.

Do I use the conf file OR  the .bat file or do I need both?

Generally one or the other.

[ewibit]

Remove the --temp-cutoff commandline or "temp-cutoff" from your config file.

was not so good
after an hour it was rest, sick and stopped completely
have the original "temp-cutoff" in config file again

Can anyone currently connect to bitminter using stratum?
I am being told stratum protocol is not supported or disabled in libcurl. Which is nonsense.

I installed Bfgminer 3.1.4 and everything was running fine.
I was tinkering around trying to build bitcoin-qt from source and changed a few things, now I get a bus error: 10 when I try to run Bfgminer 3.1.4 @ command prompt  (terminal) in Mac OS X 10.8.4

How do I fix it? I tried restarting, reinstalling and NOTHING seems to work... I am stuck using Mac Miner for now...

Seems to be an issue with Bfgminer, ran it once on a separate system (10.7 instead of 10. and after shutting it down and restarting it, I get the same bus error and NOTHNG seems to fix it...
What gives?

Did you by chance unplug and replug an erupter?

Have a look at your config file.  /Users/*yours*/.bfgminer/bfgminer.conf .  It is hidden so you may need to use Shift-Command-G from Finder to get there.  There are some 'odd' configs in there such as kernel location that came from the repository during the brew pull/compile. Delete/rename the conf file and restart BFGMiner. Once I did that, all was right with the world.  I recreated the problem and solution on 10.7 and 10.8.  I hope it helps.

I am unable to get my BFL LS running on arch. I have libusbx installed but it still won't detect it. I have been poking around and seeing that FTDI is currently not working, although bfgminer moved away from FTDI, right, so it doesn't matter? Any reason why this might not be working? Thanks!

[ajw107]

thx, but thats the problem; - I'm on Linux..

There's still many possibilities:

• You could try CGWatcher in Wine (not tried it myself, and it needs .NET 4.0, but it may work)
• You could use this python based Miner Monitor https://asktom.cf/index.php?topic=232232.0, not tried it myself, but it sound popular
• You maybe able to use this smartphone App (Windows, iOS & Android) so you can control it on the move http://www.mobileminerapp.com/, again not tried myself
• Search this subforum for monitor, there are quite a few
• Or just use Kano's (CGMiner Co-Author) simple script here https://asktom.cf/index.php?topic=28402.msg2966960#msg2966960

Hey Luke, I just wanted to say thanks for making a great miner. I was using cgminer with 25 block erupters and kept having multiple "zombies" after a short while, so far running your program they are all running smoothly.

Hi.

I built bfgminer from source (git from  a couple of days ago)  for my ARM based QNAP NAS (linux). It's version  3.1.4.

I have my NAS connected to a dlink USB hub and 7 USB eruptors plugged into that. 

Code:

./bfgminer

with no options returns:

Code:

All devices disabled, cannot mine!

I have tried :

Code:

./bfgminer -S all  

Code:

./bfgminer -S /dev/usb/ttyUSBX  

as well as trying it with -G to turn off GPU mining but with no luck.

Here is the device output from bfgminer -D -T -d?

Any help/pointers from anyone on what I might be doing wrong would be greatly appreciated.
Is it something to do with libudev.detection?
I am finding it difficult to understand the correct way to configure the new auto-detection for USB BE's. Everyone seems to do it differently.
 I know if no mining devices are found it's a USB driver problem possibly? But how to fix that on linux? (not ubuntu(ipkg based system)) (I built most of the bfgminer dependencies from source)

Cheers!

This suggests you don't have the cp210x driver (part of Linux).

It should say:

[ewibit]

what is this?
always after ~1 hour I get this with BFL LS and then nothing going on..


only restarting BFGMiner helps

[Luke-Jr]

Luke,

Is there a way for bfgminer to set the minimum difficulty?  I always thought pools decide what the minimum difficulty suppose to be and they tell miners what is the share difficulty.  But just wondering if there is a way to tell the pool, "hey, I'm fast, don't bother sending me shares lower than XXX".

Thanks,
af_newbie

[Luke-Jr]

 

It looks like a bad USB cable or something. :/

[dlasher]

^^^ happened to me today too. BFGminer complained about individual cores being "sick". Avg temps <60C.

Sorry BFGminer, back on the shelf, cgminer returns for now. Will wait another few months and try bfgminer again.

Thanks Luke.  Much appreciated.

Does that mean that if the pool I use selects say difficulty 3 for me and I can use the request difficulty function to reduce difficulty and therefore increase my share percentage/increase btc income ?

sorry bud, answer is no, while you could try, the pool would do 1 of two things:
    take requested difficulty, then jack it back up because of your aggregate hashrate
or  refuse it and keep requesting what it sent you.

LJR please correct if im mistaken:

--request-diff only works going up, not back down; and is used as a means to lower TCP/IP network chatter and bandwidth by Rasing the difficulty that your miner accepts as shares
