thanks for your answer,
the problem is that i can't even connect to Carambola 2 by $ ssh
root@192.168.1.1 - how should i run commands on the carambola 2 board?
EDIT: i've read somewhere else that it is possible to access carambola 2 via USB? How does that work? Might that be a chance to get an alternative (not LAN or Wifi) connection to the Carambola 2 Development Board?
