Hi, Recently, I bought udoo quad and I install ubuntu 12.04 current version. My udoo get frozen after put it there overnight. My udoo is running 1.Tomcat ( Tomcat installed, startup, nothing else) 2. Arduino keep on post serial.println("something") This issue happen several times, sometimes, I just open chrome and browse several web page. It hang there. Mouse , Keyboard not moving. Also I notice this board, the pin on board is not align very well, some part looks like hand made not machine made. Is there anything I can do to prevent udoo frozen? Is that possible that udoo can not pass overnight test? heat, hardware....?
