R-Car M3 SoC Documentation

Official board documentation

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

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

Change/update MAC address for Ethernet interface

In U-boot command line type: 

=> setenv ethact ravb
=> setenv ethaddr aa:bb:cc:dd:ee:ff
=> saveenv

The original (board default) MAC address can be found on the label on top of RJ45 connector.

A user who purchased M3SK board must set the above by himself.

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

Refer to Yocto page for steps necessary for running Yocto.

Serial Console

Use a micro-USB cable to connect to "Debug Serial-0" (CN10 for ws1.0, CN12 for ws1.1). Serial settings are 115200 8N1.
