You can setup the watchdog to reboot the Pi if the USB hangs and also setup a cron to reboot every 45min. This has worked very well for me in the past.
Ha... good idea. Is the concept that because it's only running for 45 mins at a pop, it never gets a chance to hang? Or can it reboot on a hang also? Since mine stops sending video, I never know just "HOW" hung it actually is. |

The Bitcoin software, network, and concept is called "Bitcoin" with a capitalized "B". Bitcoin currency units are called "bitcoins" with a lowercase "b" -- this is often abbreviated BTC.

I don’t understand the dropouts and hangs. I run for weeks on end using the Lenovo m700 tiny.
Do you guys push stick clocks hard?

I was having the same issues on my little Pi-gekko rig. I put it down to the software updates as it was fine on the first version if the new style OS but as soon as I did a second update it would randomly hang for no reason and required constant restarting. Never got to the root of the cause so ended up selling it. |

I believe there a issue with how the PI's USB and NIC share the same bus and or controller, that causes the USB/NIC to hang and become unresponsive under certain conditions. I have found this does depend on the USB HUB, the devices attached to the HUB and the number of devices. There is a lot of info regarding this on the google. The watchdog can detect an hardware hang and reboot the PI when this happens, the reboot is to catch any devices that drop out and are not auto detected again. The devices dropouts used the be a very big issue with bitfury miners. They would slowing drop out over time and the only fix was to reboot to reinitialize the usb devices (I think you can do some linux witchcraftery to do this without a reboot but I'm a linux noob so its a reboot for me). Minera was actually where I got my watchdog config from. There are instruction their thread on how to configure the watchdog. https://bitcointalk.org/index.php?topic=596620.msg7548797#msg7548797Correction: I got watchdog config from "MinePeon", but the setup is the same so no matter. |

Testing in the last week, latest Minera would run at most about 6 hours before locking up the Pi and dying. The Raspbian Lite setup is at 3 days 16 hours uptime without blinking.
I mean, the miner's blinky lights have been blinking quite a bit. Because the Pi is running steadily. USB traffic should be about equivalent to four 2Pacs at 250MHz, or ten stock sticks.

Ladies and gentlemen and whoever else, meet the Terminus R808.  Two pods running off a Pi, Raspbian with VH's cgminer. rem26 is working on a simple webconfig package so you won't have to SSH in to configure cgminer. Note that the Pi is being powered by one pod's auxilary power USB port.  What the port face looks like. We've got USB-A for 5V power out, and a mini USB for control. 12V can be drawn from either a PCIe 6-pin jack or a 2.1/5.5mm barrel jack (for running off a brick). The blue knob is used to adjust core voltage from about 0.63 to 0.80V chip-level, basically the same range as the 2Pac. It can be assembled with a vertical (pictured) or right-angle (front-facing) adjuster. This guy has an onboard microcontroller that handles fan speed via PWM, detects "ZOMBIE" condition and resets the chips automatically, and will overtemp-shutdown at 80C (to restart mining below 70C). It's a 100mm square sitting on rubber feet, but there are M3 screwholes at each corner for stacking or mounting in a case. This miner is built with 8x BM1384 hashing chips. I will be using this form-factor as a standard going forward, so newer versions with better chips will be physically compatible. For all you flashy-light enthusiasts, it's got a base blue LED and blinks white with returned shares. |

Should start manufacture this week. Once I have some tested and ready, and all the details figured out, we'll be go for sales.

I think 275MHz is reaching the upper limit of the main regulator. |

ill probably take a couple or so.. will the cgminer for these be backwards compatible with the compacs and the 2pacs so i can run them all off the same pi?

I would advise folks who are interested to email Laura (at gekkoscience dot com) so we can get a bead on market demand. Only gonna have so many of these at the start and I want to know how to divide them up.
[edit - Laura is no longer the sales rep, contact sales@gekkoscience instead]
