bfgminer crashes with more than 13 Dualminers #556

Open cbeech opened 10 years ago

cbeech commented 10 years ago

I have 93 dualminers attached to a raspberry pi running wheezy. I have compiled the head of the master with --enable-scrypt and ran bfgminer -S noauto -S dualminer:all --set-device dualminer:clock=850 --scrypt. 13 dualminers are initialised and their leds are turned on, the remaining dualminers are uninitialised and the raspberry pi crashes becoming unresponsive.

I have been able to use 93 dualminers with https://github.com/dualminer/dualminer-cgminer but would like to upgrade to bfgminer if it is possible to support 93 dualminers.

Does BFGMiner crash, or the RPi?

cbeech commented 10 years ago

The RPi crashes entirely when running bfgminer.

Doubt I can address this, I have a single DualMiner.

@luke-jr didn't you have some settings that supposedly (or may) allow more serial devices to run on a Pi?

luke-jr commented 10 years ago

Yes, but not sure that's going to help if it's crashing. If it didn't make it into docs, though, I'm not sure where I'd have saved that stuff. :(

cbeech commented 10 years ago

If there is a way of increasing the serial devices on a Pi then I will give it a try to see if it makes a difference.

I'm seeing what I think is the same problem, but with 29 DualMiners.

I built BFGMiner today from the latest sources. When I run it, the Pi completely crashes.

Since I've seen problems in the past with attempting to access GridSeed devices from an alternate miner after cgminer has run, I disabled my cgminer service and rebooted. But when I fired up BFGMiner I got the same Pi crash.

So now I'm back using cgminer, which is so old I can't mine on certain pools.

Any further thoughts on how I can get this to work or help diagnose the problem?

Maybe try starting with just 1 and adding them until it crashes? See if it's a gradual "degrade" or if it goes straight to crashing at some #
