Several sub-compact devices do not provide initial output to a video device. A serial console must be used for installation
12 Volts
- NB many small devices use 3.3 V or 5 V serial interfaces and are likely to be damaged if connected to the conventional COM socket on a PC
- USB-serial cables are available cheaply and tend to use 3.3 V interface
- some newer devices require a 1.8 V serial interface
Banana Pi
- requires serial console for initial installation
- Linux generally allocates these as /dev/ttyUSB0
minicom
- default parameters do not match Banana Pi. The following settings might need to be configured
- baud rate 115200
- software flow control Yes
- LF Yes
- CR Yes
- might be necessary to press "Enter" to get minicom to change from "Offline" to "Online" mode
Putty
TBA - might require no reconfiguration
Cubieboard
- requires serial console for initial installation
Raspberry Pi
- most software puts signal to a video port (Composite of HDMI) during initial installation
- use of a serial console for initial installation is optional
