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 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 9 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

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

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 DEVICE S25FL512

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
R-Car M2 SoC can be booted from various sources. Porter board can be booted from QSPI Flash device. Porter has two SPI Flash memory chips selectable by JP2. In a standard configuration 4MB Flash S25FL032 stores original MiniMonitor firmware (for backup/rescue purposes) and 64 MB FLash S25FL512 stores U-Boot.

Updating U-Boot
You may want to update U-Boot in case of upgrade or if the board you received does not have the U-Boot flashed. Follow these steps carefully to flash U-Boot:   Selects 4MB SPI Flash with MiniMonitor as a boot device. Use JP2 for this. MiniMonitor is loaded via SPI boot interface of R-Car M2.   Connect to serial console over microUSB. If using picocom, start it with the following command line options: sudo picocom -b BAUDRATE --send-cmd "ascii-xfr -vvs" DEVICE Refer to "Connect to serial console" section for more information.   Switch the board ON or reset it. You should see the following output on the console (version numbers can be different): PORTER(M2W) SPI_LOADER(DDR3L) V0.20 2015.07.14 DEVICE S25FL032 PORTER MiniMonitor SPI_BOOT Work memory DRAM (H'40200000-) 2015.06.04 Ver0.09c ** Program on DRAM (H'40000000-) **

How do I change/update MAC address for Ethernet interface?
In U-boot command line type: => env delete -f ethaddr => setenv ethaddr 2e:09:0a:00:xx:xx => saveenv

You should see the output Saving Environment to SPI Flash... SF: Detected S25FL512S with page size 256 KiB, total 64 MiB Erasing SPI flash...Writing to SPI flash...done The original (default) MAC address can be found on the label on top of RJ45 connector.

How do I connect an external LVDS display with touchscreen?
See an example for Boundary Devices BD101LCC1 display.

Which operating systems/distributions can be used with R-Car M2 Porter board?
1) AGL

Automotive Grade Linux (AGL) is a Linux Foundation Workgroup dedicated to creating open source software solutions for automotive applications. Porter board can be use to run an AGL distribution.

Currently (jan. 2016), this project is a work in progress but a Kickstart guide to start AGL on Renesas Porter board is already available.

2) Genivi
