Stupid forum engine makes really crappy formatting, but hopefully the idea is clear.
use [code] [/code]
but you may also then need to fix any '[' brackets in it if they match forum commands.

There are several different types of Bitcoin clients. Header-only clients like MultiBit trust that the majority of mining power is honest for the purposes of enforcing network rules such as the 21 million BTC limit. Full clients do not trust miners in this way.

Power seems to be my biggest enemy....

I am using a RaspberryPi 2 with an external powered USB hub. Even though it has 12 powered ports....It was too much to fill all the ports with the USB ASIC Miners. I was never able to get more than 4 running at a time because lack of power. Well today something happened to that hub and I need a new one.

I now know not just any powered USB hum will do.... What powered USB hub will someone recommend without breaking the bank?
Even if I have to use 2 powered USB hubs I would like to get more than 4 running from a single RaspberryPi.

Thank you

I like the Gearmo 10 port hub the best.  It runs 9 BE's and one fan just fine.

You do know your not going to make anything on BE's, right?

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?

Thanks - and Yeah this is more for my knowledge on how it works than anything else. Right now I just want to keep it all going.

I run cgminer 4.9.2 on Raspberry Pi 2 and experience constant segfaults (once in every half hour) when Antminer U3 is attached.

I use only minimum set of command line options to start cgminer, just a server URL and login/password (everything else is by default). Source code was taken from official git and compiled with gcc 4.9.2. I used CFLAGS="-O2 -Wall --march=native" compiler option and "--enable-icarus" configuration option. Linux version is 4.1.7.

Other instances of cgminer (configured for Avalon Nano ASICs) work just fine at the same time. Also, I tested same version of cgminer under MacOS X with U3, and it seems to work stable, too. So it looks like some issue with specific setup of cgminer + Antminer U3 + Raspberry Pi 2.

Is it a known problem? Is there any patch around? Anybody interested in core dumps?

If it's a crash only with RPi then it's either a specific software bug that only shows up with the RPi build - or - it's an RPi hardware problem. It's very easy to get unreliability with the RPi simply with a dodgy flash card that's hard to figure out.
Get a backtrace if you can by following the directions here:
http://ck.kolivas.org/apps/cgminer/debug/README-debug

If it changes every time it crashes and seems to be random memory corruption it's almost certainly an RPi problem and not a software problem. Many people have run this version of cgminer on RPi without any issues so my bet is on that.

You'd need to actually compile it -g -O0 to get some useful info out of gdb
The gdb dump shows no info about why the stack was corrupted.
As a wild guess try changing line 3000 to buf[1024] instead of buf[512]
This, however, can also simply move the problem if something else is causing it.
(and compiling the code differently can also move a problem)

Well supposedly I'm getting an S7 - so it would be soon after that if it happens.

Hi kano,

A little birdy told me that Yoshi was going to contact you about the S7 actually - maybe drop him a line to remind him? He does forget things sometimes....  Wink Smiley

Hi kano,

Did you receive your S7 yet - or are you still waiting like the rest of us?  Wink

where do i find how to create the file to run the miners? a cgminer .bat file runs inside the extracted cgminer program files? on c drive? i dont get how to initiate the miner? using x3 thunder and ispace.co.uk pool, but dont know the exact .bat file. Anyone have sample, i could plug my pool credentials in or even better, a simple set of instructions?
thanks a mil

Anyone had any problems with poor performance of Monarchs using firmware 1.4.5?  Mine all hash at about 25% of their expected rate.  This problem

does not happen with the units I have using firmware 1.4.2 or 1.4.3.  I have tried CGminer 4.9.2 in Windows 7 X64 and with Minera on a beaglebone.

Same issue on both platforms.

My monarch died long ago ... that someone else (not BFL) supplied me with.

BFL never contacted us about firmware changes or anything like that (or even about the Monarch until LONG after they should have) so your on your own with support of newer firmware in them since I've no idea at all what might have changed and no way to test it.
