Hi. I have downloaded the software specific to the miner and it run fine on a Debian machine. Then i moved the miner to another machine that has Gentoo and bfgminer ran fine for like a day or two and then does segmentation fault. It has happened very consistently so i ran it through dbg to get log. I don't know if there is another place where i can put this or if there is other way to get more debugging info.

Could be an issue with gentoo specific libraries that bfgminer relies on. Since this is a linux machine its easy to build the binaries...I would just do a custom compile on your system and see if that resolves the issue.

Could be an issue with gentoo specific libraries that bfgminer relies on. Since this is a linux machine its easy to build the binaries...I would just do a custom compile on your system and see if that resolves the issue.

Do i need to build with a specific config or do just clone your git and build with all options?

[jstefanop]

git clone https://github.com/jstefanop/bfgminer.git ./futurebit
cd futurebit
git checkout futurebit2_driver
./autogen.sh
./configure --disable-other-drivers --enable-scrypt --enable-futurebit
make


should do it if you have all the right dependencies installed(check the readme for those).

okay. just built and is running now although it got lots of warnings when building. i'll let you know if i have a problem in a day or two. Thanks for the help

You should see 5.4.2-38 at the top if your running the latest version.

@jstefanop 2 of my lander's fans are turning very slowly and the miners slowed down in speed.
Where can I get stock of those little fans?

You should be able to find them online, they are just 25mm fans. If your in NA, I will be launching my site soon that will have replacement fans. Otherwise talk to your local distributor they should have some extra.

[fvineyard]

I ordered some fans from Mouser electronics. $8 bucks each. I am pretty sure these will work, but I have not tried yet. They arrive today and I will install over the weekend.

Here is the link:

It crashed again with segmentation fault although it was not running that specific version. It was running 5.2.0-243. How would i go about rebuilding for latest version?

That is the latest version...my fork is just stuck on 5.2 because thats when I forked it...should probably update that. How many units are you running, and what kind of system.

THIS IS THE SUPPORT THREAD: Keep this thread on topic!

My four ML2 have been happily mining for months until this morning's April W10 update. Go figure...

bfg miner display:

------------------------------------------------------------------------------------------------------------------------
NO DEVICES FOUND: Press 'M' and '+' to add
------------------------------------------------------------------------------------------------------------------------
 [2018-05-13 10:17:37] Waiting for devices; press 'M+' to add, or 'Q' to quit



Physical:   2 x{2 ML2/Anker 9 port hub} -> USB 2.0 --> mobo{BIOSTAR TB250-BTC PRO LGA 1151 Intel B250}

Mobo is happy mining Claymore and Equihash on GPUs -> Problem isolated to ML2 path

I was able to mount & access usb drives when plugging into 9 port hub.    I can also ear ML2's being recognized when plugged into same up.  Just can't see them with the BFG 5.4.2 from the Github from this thread.

Software:  BFG 5.4.2, from jstefanop's github, on this thread, been fine for months.   
- Google found a couple threads where BFG won't detect devices, not sure how they relate here.

UART VPC Driver: Obtained from this thread, been working fine from the get go.

I'm physically away from the rig, will have a short window on the rig tomorrow, and wanted to get my thoughts in order before tackling...

I'm reckoning since this coincided with this morning's W10 update, I may not be alone.

Much obliged!

[jarvisparvis]

I had that problem i just rolled back to the previous windows update vers. and it works fine. Its the usb drivers Silicon Labs will probably issue updates. But until then im sticking to the previous version of windows. Apparantly alot of folks with Intel SSD drives had issues too...

[Weekendshooter]

Yup....   Exactly....

Hoping any USB driver update avoids the need for a BFG update....

Fingers crossed.

Thanks!

[Hoiberg]

Hi guys,

I am pretty noob on the MLD, I've got two sticks mining LTC in litecoinpool using Plugable 60W 7 port USB 3 hub.
It is working.

But my issue is low average hashspeed. My 24H average 5880 KH/s. Especially one of the miners seems to be dropping to 2.3 Mh/s.
If I restart the BFG it goes up and then drops again. It often also stops hashing and then restarts automatically.

I think I mistakenly adjusted the memory voltage pot too much/too little. I am not sure what its current memory voltage is.
So I need to know where I can find its current memory voltage.  Core voltage is running around .725 so that should not be the issue.
Also I do not know how to adjust clock rate. Can anyone share a command.

By the way I am running this on a raspi 0 through IOS.

Anyone can help?

Cheers and thanks a lot!

Also had the problem with the win update. Was not able to find the miners after the update, the usb ports gave errors.

Furthermore, was unable to reinstall the silicon labs driver package for usb as per openingtopic instructions.

After a rollback everything immediately worked again so i'm guessing there's a kink in the new windows update

Yea last windows update screwed up drivers pretty bad. Lots of other devices not working either.  I’m sure silicon labs will issue driver update to fix soon.


BTW if anyone from here is at consensus in NYC I’m there so come say hi!

[Buddy_hell]

HI

trying to run new update on RP3. Managed to get and compile, but being an idiot i cant see the bfgminer start command. I have a screen start scrypt but it does not execute giving me a "screen not found" error.

any pointers woudl be great. Currently runing v34 which needs restarting periodically.

andy

** idiot indeed - now running the screen install package! Can you add this to instruciton set as not sure this dependency is in the v34 on page 1.

Also, I have found you need to restart the pi after getting the library files otherwise they will not be found. This should be added to the instructions as well.
