The USB on the AR9331 has bugs. If you want use serial console, please use the direct serial console on 703N (the /dev/ttyATH0). It's far more stable than USB-serial converter. You may want add a USB hub between machine and 703n

  • You may need update the address/DNS to your local configuration. DO NOT FORGET your IP address.
  • If the Raspberry Pi can access internet, cgminer should automatic start
