Re: Open Source Bitcoin ASIC miner project that uses 2x BM1387 (Antminer S9)
Hey !
I can send you a lot of old S9 / S9k hashboard if needed !
For free, I juste don't want to pay the shipping but I don't care about the boards
Hey there, thanks for the offer! I believe NebulaMiner wants to / started reverse engineering ASIC communication / protocol of Bitmain S17.I can send you a lot of old S9 / S9k hashboard if needed !
For free, I juste don't want to pay the shipping but I don't care about the boards
The S9 have older chips, but since protocols may stay the same between miner generations, it could be interesting for him to look at the S9 boards.
S9 have BM1387 chips, S9k is BM1393, and S17/Bitaxe are BM1397.
I did started a reverse engineering job on the differents protocols in order to better understand BM1397 for Bitaxe driver in FW.
S9 board (BM1387) have older and different commands from BM1397.
But S9k (BM1393) are somehow similar. I did brough a broken S9k on ebay, but HashBoards are faulty so it would be nice to have good ones to see how Control Board is handling HB errors...
I will contact you @iwantmyhomepaidwithbtc2 to see what can be done
thanks for the help.
