Hi,
My BJ was working fine about 25 days, and starting from today, raspberry pi keeps restarting every minutes, so in reality it stopped working. I don't know what caused the reboot, hardware, cgminer or the pi it's self. From the monitor, it can be any time, even last second it's hashing and received and accepted share, then suddenly rebooted.
Has anybody have the same issue. How should I diagnose this issue? Thank you very much for the help!
It turned out for me, an unstable pool can keep my pi rebooting. After switched back to eligius everything recovered. The first time I learnt that. Also thank you for all your help, I really appreciate. The reason I want to use the pi instead of my computer is everything is setup on pi, monitoring, watch dog, user interface etc. I don't bother to make a full system working... Also since the SD card has limited writes, can I just burn the image into a hard drive, so I can have the whole system running on a dedicated computer? Thanks! |

damn i feel sorry for you. If you want to get rid of a unit or 2 let me know id love to buy some. Assuming they actully work at 400 and its just the connection that is making them seem slow
This is just one unit and yes it works at around 385 GH/s at the pool. Whenever it reconnects it shows up as a new unit in cgminer but it is not. I'm hoping a software/firmware update will make it run as stable as my older ASICs from BFL and AM. (e.g. run and forget). I OCed my BJ to 610, and I can get 410GH/s at pool stably, never need a restart. Which pool do you use? I am using eliguis, and don't even have a backup pool. Would you please give any recommendation? |

Hi Everybody who has a BJ running
I have got my BJ(400GB) up and running for about 1 day, I am using Eligius as the pool. I can mine about 0.08BTC a day(Which I think it will take very long to get my investment back). Is this a good profit? What is your profit a day? Is there any other more profitable pool you recommend? Thank you very much!

Also Phil, I have two more questions:
1. I can see some errors in cgminer out put, how to fix them?
[image snipped]
As you can see the hardware error is keep going up, is this normal?
Also the first line of the scroll-able zone there is an error message:
HFA 0 attempted reset got err:(-5) LIBUSB_ERROR_NOT_FOUND
How to fix it?
2. Second, with default configuration, from cgminer's interface I can see the hash rate is always around 400GH/s. But from pool statistics average is only between 320 to 380. How to explain that? Can I say my BJ does not perform as described in specification?
Thanks you!
[image snipped]
In both these cases, we hope the new firmware will help correct these issues. It's absolutely normal to have some hardware errors. We have fixed the source of some of these in the upcoming firmware. Con Kolivas is also working with us to make many improvements in cgminer, so we will release both together as soon as we can. You should be able to get about 400Gh/s at the pool (average) though you might have to clock to 600mhz to get it at present. My test system at http://setup.hashfast.com/rpi/ is running at 600, it's got a bunch of errors, but as you can see from the pool stats on Eligius it's cruising along at about 428Gh/s for the 12 hour average: http://eligius.st/~wizkid057/newstats/userstats.php/17ao2fT7gbnnKYpMd7x29E8p4oGdE87AhdThe longer timeframe stats on Eligius tend to be more accurate and useful. The stuff under 3 hours is hit-or-miss. -Phil Hi Phil, I would like to OC to 600MHZ, but does that void the warranty? Anyway since the warranty is only 10 days(which does not make sense for such an expensive device), do you see at what chance I will need it since it is running smoothly for about a day already? Or should I call the warranty under the reason device does not perform as described and let Hash Fast "FIX" it for me? If the official fix is to OC it, then I don't think that will void the on going warranty right(even it's not long)?  |

Thank you ckolivas. I figured that it's the permission issue. And I followed the guide and added current user into plugdev group by issuing:
sudo usermod -G plugdev -a `whoami`
But it does not fix the problem. In this case does that mean I can only run cgminer under root user? Or you think it's not the issue of permission? Please kindly point out.
Also I logged into my RB Pi and can see cgminer is running under minepeon user and that user belongs only to minepeon group.
Anyway thank you for you help, I have made my RB Pi working now, so have no chance to test BJ on my linux box for now. Will report when I get a chance.
That wasn't all the instructions that were in the readme, you need the udev file installed. That other command is usually not needed in fact - but I don't know how permissions are set up on minepeon as the instructions revolve around regular PCs running regular PC distributions of linux and I'm no RPi distribution expert. It is always a permissions problem if it goes away as root. Thanks Con. The RPI is set up to run cgminer as the user "minepeon". By default it is correctly set for this, no changes to UDEV or permissions. Targetalk: If you are compiling your own version, you need to be sure you have enabled the HashFast driver support before compiling: ./configure --enable-hashfast You should not need to do anything else if you have correctly run the autogen script. Of course none of this is needed if you use the default version we supply. We will be sending out Con's latest as soon as everything is finalized and tested. -Phil Hi Phil, Yes, I compiled cgminer with --enable-hashfast on my xubuntu. It can detect HF device but can not enable the device, that's why I think it's permission issue. |

Hi Phil, It seems that it is the issue of the SD card you shipped. I replaced that card with my sandisk which is working now. I think the SD card you provided is too thin so that the pins do not contact properly in the slot in the RB Pi. My sandisk card is much thicker and after I plug it in, I can feel solid contact. Anyway, thank you for your help. I can see it's hashing at 415G/s but for your default BTC address, will switch to my address and see. Awesome, Glad to hear it! Is the original SD card we shipped actually a "no name" Micro SD inside an adapter with the Raspberry Pi logo on it? We got those specifically because they are "official" RPI cards, so they'd be the most likely to work well, but it's turning out that they stink. We'll test some different ones for the next batch. BTW, any time you build a new image, the first time it boots, it makes a new bitcoin wallet (viewable on the "wallet" page of the web UI), and begins mining with that wallet. Be sure if it made any BTC that you don't forget to collect it! If you make a backup from the settings page, the wallet is also backed up and restored. If you want to change to a new wallet or mining username, that's done on the "pools" page of the web UI. If you ever restore from a previous backup, it puts all your original settings in, so it's a good idea to make a backup once you get things dialed in like you want. (In case an SD card dies or something.) -Phil Also Phil, I have two more questions: 1. I can see some errors in cgminer out put, how to fix them?

I can not say it's the card's issue because it works fine on my computer, I think it just does not fit well with the slot in the Pi. But the fix is definitely use a thicker card. I don't really understand the collection from the default wallet? Do you mean there is a default wallet created on the Raspberry Pi and there could be BTC already generated during the test? In my case cause I have never get original card boot successfully, and just created new card from downloaded image, does that mean I lost the original wallet already? And I also don't understand how to use that wallet and transfer the BTC out? Is there a wallet application on RB Pi? Or I just recover this wallet on another computer using the key pare? Thanks! |

Thank you Phil. Actually I did what the instruction says. The issue is that the LED indicator of the port on my switch does not even show the internet connection is every enabled on RB Pi. So I think it has no chance to download any uploads. Are you sure the reload can fix the NIC issue? Anyway, I am trying, will update soon. Thanks again!
We've shipped tons of these things, and I have yet to see one with a bad NIC. There have been plenty of bad SD cards though. Note that a bad SD image will fail to initialize the NIC and there will be no ethernet lights or link. Follow the reload instructions and then be sure you can see a 94meg partition with the following files: total 24M

2.0K cmdline.txt
2.0K cmdline.txte
2.0K config.txt

470K start_cd.elf
2.4M start.elf
3.4M start_x.elf If not, see if you can grab another SD card (2G min) and try the image there. Seems like some people have had difficulty installing the image, so be sure to uncompress the image first and then use the proper method to write the card. Tech support can send you one if you like, simply send an email with the subject "Replacement SD card request" as the subject. -Phil Hi Phil, After reload I can see 94meg partition with above files(But no config.txt~ and cmdline.txte).

Yeah, I just got my BJ yesterday, I had the same issue. The brand new shipped BJ just does not start up. I have confirmed Raspberry Pi is defective, cause the HDMI has no output to the monitor at all. Do you know how to diagnose the Baby Jet itself? After I plugged in power cord and turned on power switch on the power supply, nothing happened. I can see there is power switch and two LED lights on each side, but they are just dark, do you those two LED light are supposed to be on after the power supply is turned on? Thank you!
Please reload your SD card, that is all that's wrong with your Raspberry Pi. Note that the monitor will not show anything for about 3-4 minutes when first plugged in, as it must get the current software and install it first. Then, it will reboot and you should get a display on any HDMI monitor or TV. Note that you do not need a monitor. The terminal screen is available from the web interface. Here's the SD reload instructions: http://hashfast.com/how-to-update-babyjets-raspberry-pi-sd-card-software/Please got here for setup instructions and to access your Miner's web interface after it updates (3-4 minutes): http://setup.hashfast.com/Sorry for the trouble, but you should be able to get up and running within about 20 minutes total if you follow these instructions. -Phil Thank you Phil.

Theres 2 buttons on the bottom left portion of the board. You can try pushing the right one. This worked for me and someone else here.
Really, there are so many secrets... I pushed the right button, and all fans started running for about 10-20 seconds and then shutdown. But I still got the same error messages: tie@rig07:~/cgminer$ ./cgminer -n [2014-02-04 23:35:25] USB all: found 3 devices - listing known devices .USB dev 0: Bus 2 Device 45 ID: 297c:0001 ** dev 0: Failed to open, err -3 [2014-02-04 23:35:25] 1 known USB devices If run cgminer directly, got those: [2014-02-04 23:38:21] Started cgminer 3.12.0 [2014-02-04 23:38:21] USB init, open device failed, err -3, you don't have privilege to access - HFA device 2:48-i1 [2014-02-04 23:38:21] See README file included for help [2014-02-04 23:38:21] Hashfast detect (2:48) failed to initialise (incorrect device?)

Read through HF-Engineer's posts, they've been very helpful.
Thank you. Would you please let me know where I can find those posts? Go back to page 19, click on his name to get his profile, then click on read last posts. Thank you, sorry, I am really new. By the way do you have any HASHFAST rigs running? |

Thank you for you help minternj.

The fans wont turn on until you have mining software connected. plug it into your pc and run cgminer. Oh and open it up and make sure all the cables are connected. Some have reported some loose cables particularly the ones in the upper left side of the hashing board.
Thank you for the response. I connected BJ to computer, and run cgminer(3.7.2): export DISPLAY=:0 export GPU_USE_SYNC_OBJECTS=1 ./cgminer -n cgminer just does not see any USB device. I understand that the fan connected to the hashing-board could be controlled by cgminer. But there are two case fans(they are directly connected to the power supply) and even the fan inside power supply don't run. I think here I just don't know how to diagnose if at least the power supply is working. Can anybody who made your BJ running already tell me please do you see the LED in front panel is on when it's running? Do two case fan fun when turn on the power? Do you need to push the power button in front panel to turn on the machine or just turn on the switch on power supply is enough? Thank you very much! For cables, I just don't know how many cables should be connected to the board, I can see there are two 6pin PCIE power cables and 1 5pin white power cable, also 1 fan cable, 1 USB cable are connected. I can see the cables from front panel are not connected to any where. Thank you for any help! |

It seems to me that I've received a broken bj.
Has anyone had any luck returning or exchanging them??
From Hashfast that just responded to my week old RMA request: Thank you for your message. We are currently receiving a very high volume of customer support cases, and as a result, we might be slower to respond than usual. However, we will get back to you as soon as we can. You can check the status of your message at the following URL: https://hashfast.fogbugz.com/default.asp?blah-blah-blahYou may want to save your case's tracking ticket: blah-blah-blah Please reply to this message if there's anything else we can do for you. -- HashFast Support support@hashfast.comOkay, HashFast is swapped. Canned replies, trouble tickets that go nowhere and all the while asking if there is anything more they can do for me. I'll cut them a week or two break... (And KNCMiner was just like this in the beginning. But only a month late and their second batch Jupiters were under $5K and are now doing 670GH/s. People that ordered the second batch got their Jupiters under three weeks from the time of payments. As far as USD flow, Jupiters are pure profit miners now.) What is the status of your support ticket? I just checked the one I made yesterday where I asked if I could return or exchange my BJ underwarranty and I noticed it was marked as CLOSED with no response from HashFast at all. I'm pretty angry about this. I don't understand how they could deny a warranty claim made just hours after I received the unit. Its still hashing now, btw, but averaging just around 220 GH/s :-/. Yeah, I just got my BJ yesterday, I had the same issue. The brand new shipped BJ just does not start up. I have confirmed Raspberry Pi is defective, cause the HDMI has no output to the monitor at all. Do you know how to diagnose the Baby Jet itself? After I plugged in power cord and turned on power switch on the power supply, nothing happened. I can see there is power switch and two LED lights on each side, but they are just dark, do you those two LED light are supposed to be on after the power supply is turned on? Thank you! |

Sorry guys. I just got my BJ yesterday. But Raspberry Pi does not work in first shot, there is no display on the monitor at all, I even purchased a brand new monitor($200 wasted), and NIC port on switch is never on. I tried to contact them, there is no reply yet. While waiting for the reply. I would like to try mining on a linux box(xubuntu).
Can anybody kindly help me on how to install driver and start testing my BJ with cgminer? Which version of cgminer should I use and what parameters shall I pass to cgminer? Millions of thanks in advance!
Also there is a power button with two write LED on the two sides in front panel, but after I plunged in the power cord, there is no LED light indicating the power is on, is this normal?
