Host(OpenWrt + Cgminer)

TP LINK WR703N

The USB on the AR9331 have bugs. if you want use serial console, please the direct serial console on 703N (the /dev/ttyATH0). it's far more stable then USB-serial convertor.

Raspberry Pi

• 8GB Memory card: http://item.jd.com/632744.html
• Reflash: sudo dd if=openwrt-brcm2708-sdcard-vfat-ext4.img of=/dev/sdb bs=4M #/dev/sdb is your memory card

Avalon2 prototype

This design is use the Avalon first product design, replace the A3256 with A3255, some hardware pins modify and use different FPGA firmware. please check here for details and all design files and firmware files.
