Hi All.

Seems all is fine actually :P

I connected a ethernet-cable, and saw that 192.168.1.3 is assigned to
cubieboard-2 (but still no login-prompt on the serial-console).
However, when I sshed using debian/debian, I got into the board !!

Extremely sorry for the noise.


Thanks and Regards,
Ajay
