Quick Start How To

This sections describes steps that are necessary to run a "Hello, World!" application using Yocto build. Both X11 and Wayland are supported.

Build Yocto image

Refer to R-Car/Boards/Yocto for steps necessary for making a Yocto image.

Connect 12 V power supply to the board

Use 12 V power supply with a 5.5 mm barrel plug. The power supply should be able to provide 5 Amps.

Connect to serial console

Use a miniUSB cable to connect the PC to R-Car M2 Porter board. CN18 must be used on Porter side. It is routed to SCIF0 in the R-Car M2 via a CP2102 interface converter chip.

On Linux, CP2102 driver is included with kernel versions >=2.6.12. Windows driver and sources can be found on Silicon Labs website.

Serial settings are 38400 8N1. Any standard terminal emulator program can be used.

On Linux:

picocom

sudo picocom -b 38400 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    : 38400
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 38400 -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

Switch SW26 "Power" to switch the board on. Blue LEDs should lit up. Then you should see the following output in the terminal:

PORTER SPI_LOADER(DDR3L) V0.19 2015.02.12

Hit any key to stop autoboot:  0

Quickly hit any key to get into U-boot command prompt. Use SW9 Reset to reboot the board when necessary.

You should see the following:

Hit any key to stop autoboot:  0

Configure U-Boot to boot over TFTP + NFS or from a micro SD card

Refer to Yocto page for steps necessary for running Yocto.

Bootloader

TBD: provide instructions for updating the bootloader when second, backup, SPI flash is available.
