Quick Start How To
This sections describes steps that are necessary to run a "Hello, World!" application using Yocto build. Only Wayland is supported.

Build Yocto image
Refer to Yocto for steps necessary for making a Yocto image.

Connect 5 V power supply to the board
Use 5 V power supply with a 5.5 mm barrel plug. The power supply should be able to provide 4(Min) ~ 8(Max)Amps.

Note
 * The recommended value is 8 Amps. But, user can use 4 Amps. and 6 Amps. (depends on the use case).

Connect to serial console
Use a microUSB cable to connect the PC to R-Car Starter Kit Pro (M3ULCB) board. CN12 ("CPLD/DEBUG") must be used on Starter Kit side. It is routed to SCIF2 in the R-Car M3 via a FT232 interface converter chip.

On Linux, FT232 driver is included with kernel versions >=2.6.12. Windows driver and sources can be found on FTDI Chip website.

Serial settings are 115200 8N1. Any standard terminal emulator program can be used.

On Linux:

picocom

sudo picocom -b 115200 DEVICE replace DEVICE with the proper tty device name, for example /dev/ttyUSB0. Running dmesg | tail can help locating proper device. After the successful connection, picocom should display:

picocom v1.7 port is       : /dev/ttyUSB0 flowcontrol   : none baudrate is   : 115200 parity is     : none databits are  : 8 escape is     : C-a local echo is : no noinit is      : no noreset is     : no nolock is      : no send_cmd is    : sz -vv receive_cmd is : rz -vv imap is       : omap is       : emap is       : crcrlf,delbs, Terminal ready

Use Ctrl+A, Ctrl+Q to exit picocom.

minicom

sudo minicom -b 115200 -D DEVICE replace DEVICE with the proper tty device name, for example /dev/ttyUSB0. Running dmesg | tail can help locating proper device. After the successful connection, minicom should display:

Welcome to minicom 2.6.2 OPTIONS: I18n Compiled on Aug 7 2013, 13:32:48. Port /dev/ttyUSB0 Press CTRL-A Z for help on special keys Use Ctrl+A, Q to exit minicom.

Power on the board and go to U-Boot prompt
Short-press SW8 "Power" to switch the board on. Then you should see the following output in the terminal: Welcome to minicom 2.7 OPTIONS: I18n Compiled on Jan 1 2014, 17:13:19.
