The evaluation board contains an on-board Silicon Labs CP2102N USB-serial converter. Connect the included Micro-USB cable to the Micro-USB jack labeled USB-UART Bridge:
The serial converter does not require additional drivers on Windows and Linux.
For Mac OS, drivers are available from Silicon Labs: http://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
The Q7 modules has two external UARTs:
UART0 is, by default, used for the serial console for interactive login. UART1 is unused by default and can be freely used for machine-to-machine communications or other purposes. The switch UART0 / UART1 cross-switches UART0 and UART1 between the RS232 / RS485 jack and the onboard USB-serial converter:
Switch Position RS232 / RS485 jack connected to: USB-serial converter connected to: UART0 UART0 (interactive console) UART1 UART1 UART1 UART0 (interactive console) For interactive login through the USB-serial converter, make sure the switch is on the UART1 position
Picocom can be used to connect via the serial line (assuming the USB-serial converter is USB0):
picocom -b 115200 /dev/ttyUSB0 Note Make sure to disable software flow-control (XON/XOFF). Otherwise serial input may not be recognized.
After system bootup, the login console appears on the terminal:
rk3399-q7 login: You can log in as root with password root or as user user with password user.
