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
2014-06-06
- MM version: 331406-35fef7040
- 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
- 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
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
