I've put up the first release of cgminer that I've personally tested on real hardware with substantial improvements:

For those who want to update to the newest version (3.11.0) of cgminer on minepeon:

After MineForeman has updated the repositories you can do the following:
(edited 1/27/14:Version 2.4.3 of Minepeon has an issue with the the git config)

ssh to your pi then type:
nano /opt/minepeon/.git/config
 -look for "url = git@github.com:MineForeman/minepeon-base.git" change it to "url = https://github.com/MineForeman/minepeon-base.git"
 -save chnages and exit nano
cd /opt/minepeon
git pull

(optional: update http gui)
cd /opt/minepeon/http
git pull

Reboot your Pi.  Reconnect to the web gui. You can then look at the "Miner Version" field and see what version of cgminer is running.

Mineforeman usually waits a short period of time before updating the Minepeon repositories with the newest versions of cgminer and bfgminer.  So the above instructions might not update you to cgminer version 3.11.0 yet. If you are like me and need the newest version right now, then you can  compile cgminer yourself.

ssh to your pi then type:
wget http://ck.kolivas.org/apps/cgminer/cgminer-3.11.0.tar.bz2
bzip2 -cd cgminer-3.11.0.tar.bz2 | tar xvf -
cd cgminer-3.11.0
./configure --enable-hashfast
make
mv cgminer /opt/minepeon/bin/cgminer

Reboot your Pi.  Reconnect to the web gui. You can then look at the "Miner Version" field and see what version of cgminer is running.

I hope this helps.   I have been up for about 40 hours now. I'm on a caffeine rocket ship that is finally making it's reentry back to Earth.  Please excuse me if the above post is hard to follow. I will pretty it up a bit, once I've landed.

ckolivas, if you are still around:

Given all the controller hassles people are having with the RPi's, once the compiled 3.11 binaries are up at spaceman.ca, is there any reason not to donate the RPi to the Salvation Army and control my BJ, along with whatever comes out of the MPP, from the old Mac Mini I have lying around?

Maybe it's just me, but that just seems a hell of a lot simpler.

RPi = 3 watts = $2.76/yr  (but does the power supply eat more?)
Mini = 14 watts = $12.89/yr  (@$0.105/kwh)

I'll splurge on $10/yr in electric for the desktop operating system. No wifi stick hassle either.

And can the RPi run six HF boards at once? (BJ+upgrade+MPP?)  I'm assuming the mini can. Not even any need for a USB hub.

So after spending hours and hours trying different things, I found the 1 minute solution, that no one had suggested.

I plugged 2 hashfast devices into one Raspberry Pi.  And it works.  All of my baby jets were hashing overnight, so the problems appear to have been with 2 of my raspberry pi controllers.  So now I have two "double" ones.  It's hot-swappable too, so you just plug it in all turned on and it detects it and starts it to mining within seconds.

It's funny that I ordered 5 Raspberry Pis to be delivered overnight but that was not necessary oh well I guess I will have extras to toy around with now.

Is there an easy way to overclock these via the minerpeon "Miner Startup Settings"? Right now I'm having to SSH in to edit my miner.conf, which is really annoying.

Also, I've noticed SSH access on like half my babyjets is not working.

Same I can't ssh into mine either. haven't had the chance to hook up into console to mess around.

ssh isn't available on my first delivered unit. If my later units don't have access either I guess I will repurpose a real machine to be a controller -- ghetto sierra.

Personally, I don't think a Mac Mini or atom nettop or something that like that is ghetto at all, compared to the loose RaspberryPi flopping around, hung by a USB cable. Or, worse, a half dozen RPi's hanging on USB cables, buffeted by the wind coming out the exhaust, and with sketchy SDRAM cards going belly up.  Oh, and the ghetto USB wifi stick hanging out...

And, more seriously, it's only a few RPi's before you are burning the same juice as an efficient small PC.  I dunno, I suppose it depends on your setup and style, but since the general release cgminer does the same as the RPi, I'm ditching the little box.  Although if my controller goes down, it's more catastrophic (everything stops, not just one machine!), but I'd rather maintain one controller than maintain a fleet of them.

can someone post a picture of the power supply jumper (the white connector on the PSU) ? just got my bj today, but it won't power on. I suspect mine is jumping the wrong pins.

Open the baby jet. On the baby jet board on the bottom left side there are 2 buttons. Push the right button.

wow, thx. did i miss some obvious documentation somewhere?

[minternj]

Nope, its not documented anywhere.

added: I think it has something to do with the 4 jumper cables on the top left. Power, reset, pwr led, hdd led. I'm curious if one of mine and yours might be swapped.

if someone with a Jet can tell me the order their cables are plugged into this, id appreciate it.

so it comes underclocked

yup.. for overclock just change the cgminer settings.

default cgminer argument is --hfa-hash-clock 550

try changing it up a little at a time  so go to 570, 590, etc.

The RPi is a toy and a piece of shit. Why anyone would run thousands of dollars worth of equipment off it is beyond me. Toss it and connect your devices to a real PC or laptop.

This. I have 5 of them that I've been using to run my other miners (BFL and BitBurners) and they are notoriously unreliable. Every once in a while the SD cards will die necessitating a rebuild of the whole image. And the USB ports are the worst. Even with a powered hub they aren't able to drive my bitburners anymore and I ended up having to buy a tiny computer and putting Linux on it.

Does anyone know how to set up minepeon so it uses a static IP address. I don't want to use DHCP. I tried using wicd-curses to reconfigure it but it didn't seem to work. I'm familiar with setting up a static IP on my raspbian pis but not on arch linux.

Is there a max that I can run on a computer? With the FSB or CPU bottleneck or something?

My driver code uses small amounts of CPU and usb communications even at 1.4TH on my sierra so I'm guessing with a modern CPU you could run maybe 20 sierras from the one machine. On the other hand, people who are running multiple devices at the moment are having problems presumably some kind of communication issue and the engineer I'm in contact with thinks it's a firmware related issue rather than software at this stage.

Great thanks for this info. I guess I will just wait for an update.

[tacotime]

What are the instructions for running cgminer on windows with BJ attached via USB?  Or at least a commandline?  Is it plug and play?
