Tested USB HUB

Development

Debug port

Using BFGMiner

Avalon 3 units communicate with a UART, usually attached to your host via a generic USB UART adapter. First, figure out what COM port (or /dev/ttyUSB on Linux) and run BFGMiner with:

bfgminer -S avalonmm:\\.\COM22 --set avalonmm:clock=450 --set avalonmm:voltage=0.6625 --set avalonmm:fan=80

Firmware

703n/RPi Host Firmware

After 20140320, the Avalon2 firmware support both Avalon2 and Avalon3 out of box. Please download the firmware here:

MM Firmware

2014-08-08

  • MM Version: 331408-a15cac80
  • Add long coinbase1 support.
  • Support p2pool (Avalon project have a server for p2pool in HK, Domain name: p2pool.ehash.com)
  • Disable DEBUG when release. Cleanup the gpio LED and reset code, etc.
  • Update protocol.md

2014-06-06

  • MM version: 331406-35fef700
  • Turn on the red led when the module id was match.

2014-05-27

  • MM version: 331406-fe02da80
  • Add code for turn on red LED
  • When all those two temperature sensors bigger then 90C. power off ASIC.
  • Clean old local works when get detect message
  • Add one quick poweroff self test, indicator by red LED.
  • Known Iusse: All modules(connect to one usb-serial port) red led will blinking when turn on any one of them

2014-05-04

  • MM Version: 331404-dbb0c7c0
  • Support newest ADP board
  • Fixed a typo on read temperature
  • Change default modules count from 3 to 4

2014-04-17

  • MM Version: 331404-b191ace0
  • Add ASIC core test code, host application is avalon3-a3233-modular-test.py
  • Fix the power good shifter, it is binary format. 0x1F mean all 5 power module are good.

2014-04-01

  • MM Version: 331404-ed2bbc80
  • When temp > 90C. MM will power off all ASICs
  • Make the Avalon3 MM 100% compatible with Cgminer Avalon2 code
  • Please use the Avalon2 703n/RPi firmware after 2014-03-20. the firmware will support both Avalon2(A3255) and Avalon3(A3233). PLEASE NOTICE
    • The voltage range is different
    • Voltage: 0.6v ~ 0.8v
    • The frequency is Mhz not MHs under Avalon3. so the range is
    • Frequency: 400MHz ~ 650Mhz (MHz * 11.81 = MHs)
    • For example: if you config the Frequency to 400 under Avalon3 that mean 400 * 11.81 = ~4.7GHs

NEXT-TESTING

  • NOTICE: Only for testing

Design file

You can put 7 or 10 chips per small miner. 

7 chips: high hashrate with more power consume
10 chips: high hashrate with more ASICs. save more power

20140319

  • Fix one component footprint

20140317

  • Init version
