SUPPORTED DEVICES Currently supported ASIC devices include ASICMiner's Block Erupter USB miners, Avalon, and Butterfly Labs' SC range of devices. AVALON Currently, Avalon boards are supported only by connecting them directly (or via a hub) to a regular PC running BFGMiner. It is also possible to install the OpenWrt packages of BFGMiner to the Avalon's embedded controller, but this is not a simple task due to its lack of available flash space. To use the Avalon from a regular PC, you will need to specify two options: First, add the -S option specifying the avalon driver specifically. For example, -S avalon:\\.\COM9 Next, use the --avalon-options copying the command as used by the internal router used by the Avalon. eg: --avalon-options 115200:24:10:45:282 The values are baud : miners : asic count : timeout : frequency. Baud: The device is pretty much hard coded to emulate 115200 baud so you shouldn't change this. Miners: Most Avalons are 3 module devices, which come to 24 miners. 4 module devices would use 32 here. Asic count: Virtually all have 10, so don't change this. Timeout: This is how long the device will work on a work item before accepting new work to replace it. It should be changed according to the frequency (last setting). It is possible to set this a little lower if you are trying to tune for short block mining (eg p2pool) but much lower and the device will start creating duplicate shares. Sample settings for valid different frequencies (last 2 values): 34:375 36:350 39:325 43:300 45:282 47:270 50:256 Frequency: This is the clock speed of the devices. Only specific values work, 256, 270, 282 (default), 300, 325, 350 and 375. If you use the full curses based interface with Avalons you will get this information: AVA 0: 22/ 46C 60%/2400R The values are: ambient temp / highest device temp set fan % / lowest detected fan RPM.
