[Setup Guide] Blackarrow Bitfury 16 chip board support and tuning thread

[numnutz2009]

1. Sooooooo i had a few questions about these miners…..i finally got them workin a while ago but when lookin online for controllers i saw  where blackarrow says 1 v1 controller can handle 6 mining boards each but when i try 6 i get nothing but "bab0 delay getting work reply" errors allond with a few "accepted" messages but mostly the delay errors. when i remove the 6th board the errors go away. when i use a good board from another group of good miners to make sure the board i added the first time was working fine suddenly the delay errors come back lol….i just dont get it.

I soldered the wire to bring the last boards spi voltage up to 1.7-1.8v and even without doing that it happens so with or without the wire it gives the same errors. when 5 are hooked together in a chain they dont get the error but no matter which chain i use to add the board to the same thing happens in cgminer. I made the changes sugested in this thread too and those didnt help stop them. my pi is at 900mhz so its overclocked and not runnin at stock speed but even then it happens. I cant find any support for these damn things except what this thread has and like before im very grateful that some folks took time to post their experiences about setting these up.

black arrow does NOT reply except for one email that looked more like a sales email for their prospero x-3 and not a reply to actually help a buyer out. ontop of that they wont give the files needed so we can make our own effin controllers cause clearly they didnt make enough to handle the amount of users that fried their controller traces due to hooking them up backwards but with the small amount of support they provided im not suprised so many fried :/.

2. what is the switch on the controller for?? i flipped it on one miner and no matter which way i had it the controller powered up and powered the pi and i havent seen anyone else say anything about it so what does it actually fricken do?!?! its weird….its not labeled at all lol.

3. ne one have any v2 controllers they want to sell??

My guess here is increase the timeout setting for cgminer so that it waits a tiny bit longer for work replies? Not sure if you can set that on the fly or would have to recompile.

I to need a v2 controller. shame we cant get the pcb files and just get bulk produced cause like you said black arrow dont respond to emails and all controllers out of stock

the link above has the controller board files if you want to give them a quick download and check them out. this will help people like me make these boards and repair them without having to figure out what each component rating is and so on blahh blahh but ya hopefully others can benefit from these files. idk what app opens this format but i also havent tried finding out yet because im busy repairin cointerra miners but i saw the email on my phone and wanted to post the info so others know too. the files were justtttt uploaded so they are fresh fresh fresh. enjoy .
