USB BLOCK ERUPTER DRIVER
To use the Avalon from a regular PC, you will need to specify two options:įirst, add the -S option specifying the avalon driver specifically. Not a simple task due to its lack of available flash space. OpenWrt packages of BFGMiner to the Avalon's embedded controller, but this is

set option is to program the CP2102 chip so they have unique serial numbers To set different frequency and voltage settings for multiple U3 miners on a set antminer:voltage=x800 -set antminer:clock=237.5 Number of nanoseconds each hash takes at the given configuration. Must be provided as hexadecimal configuration codes. Voltage format for the U3 is not documented by the manufacturer, thus S antminer:all -set antminer:chip=BM1382Īdditionally, for optimal performance you will need to set voltage, clock, and For example, to scan all devices, you can use: The U3 does not support autodetection, so you will want to use -scan-serial to For a single blade off a raspberry Pi make sure you have configured GPIO pin 25 correctly (see below) and scan viaĮcho out > /sys/class/gpio/gpio25/directionįor multiple blades using USB Dongles connected to a pi make sure the reset pin on the alcheminer board is connected to the RTS/DTR pin on the dongle board, and option -setĪLC:mode=1 added to startup command line. set also supports running blades off a Raspberry Pi directly or with USB Dongles. You can also set the frequency per board by specifying the tty port: MHz increments (driver will default to 352 MHz if these conditions are not met).įrequency is set with the following -set option: The driver supports custom frequency settings in the range of 200-400 MHz in 16 (the four ttyUSB ports are auto detected by all) S ALC:all -S ALC:/dev/ttyO1 -S ALC:/dev/ttyO2 -S ALC:/dev/ttyO3 To detect all the blades you need to manually probe it The driver has been designed to run each of the 8 blades inside an AlcheMistĢ56 as a separate miner. This driver requires the latest FPGA firmware flashed on the blades (stockįirmware has major bug and won't run properly with this driver). Need to experiment with a good queue setting to control how much work BFGMiner Timeout/clock/reg_data combinations, however!Īdditionally, since the controllers are underpowered for these devices, you may You can probably use either one, but the 350 MHz clock performsīetter than the 200 MHz clock. Notice how there are duplicate settings for timeout, clock, reg_data, and

None of the device attributes are autodetectedĪt this time, so you must also tell BFGMiner this at runtime with a series of WhenĬonfiguring, use the -enable-bitmain option to build the 'bitmain' driver used Series (both USB and blades), a large variety of Bitfury-based miners,īitmain's Antminer S5 and U1-3, Butterfly Labs' SC range of devices, HashBusterīoards, GekkoScience's Compac USB stick, Klondike modules, and KnCMiner'sīFGMiner must be compiled for and run on the embedded controller.
