Serial Console

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

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
