Several sub-compact devices do not provide initial output to a video device. A serial console must be used for installation
Interfaces
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
- Linux generally allocates these as /dev/ttyUSB0
Apps
see Terminal_Emulation for suitable apps to use with the serial cable
Devices
Banana Pi
- requires serial console for initial installation
- default parameters for terminal emulators might not match Banana Pi. The following settings might need to be configured
- baud rate 115200
- software flow control Yes
- LF Yes
- CR Yes
Cubieboard
- requires serial console for initial installation
- uses same parameters as BananaPi above
Raspberry Pi
- most software puts signal to a video port (Composite or HDMI) during initial installation
- use of a serial console for initial installation is optional
