New H3SK
[S/N 3001-3300 ]) mainly changed the followings.
 * The R-Car H3 additional production SK( RTP0RC77951SKBX010SA00 )
 * 1. Displayout Connector(CN4) moved to the upper side of the board.
 * 2. Added protection circuit.
 * If you incorrectly input 12V to H3SK, it doesn't break.
 * On the other hand, H3SK doesn't accept power supply of 5.15v or more by the protection circuit.
 * Recommended AC Adapter:

Kingfisher (R-Car Starter Kit extension board)
Instruction of using H3SK with the Kingfisher board located here http://elinux.org/R-Car/Boards/Kingfisher

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 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 Premier (H3ULCB) board. CN12 ("CPLD/DEBUG") must be used on Starter Kit side. It is routed to SCIF2 in the R-Car H3 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.

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 =>

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 H3SK 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/ws2.0). Serial settings are 115200 8N1.
