MM Firmware

2014-06-06

• 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-dbb0c7c
• 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

• Fix one component footprint

20140317

• Init version
