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 3 Amps.

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 Silicon Labs 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

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

Refer to Yocto page for steps necessary for running Yocto.

How to prepare and boot from SD card, eMMC

This section describes steps that are necessary for preparing and booting from SD card.

Preparing SD card

In order to prepare you SD card, follow these instructions:

1.Partion your SD card to set 1 partition and ID=83 (Linux)

$ fdisk /dev/mmcblk0
-> d
-> n
-> p
-> 1
-> t
-> 83

2.Format this partition to ext3 (or ext4)

$ mkfs.ext3 /dev/mmcblk0p1

3.Mount this partition on your host to any directory and upack the core-image-weston-XXXX.tar.bz2 into mounted folder.

$ mount /dev/mmcblk0p1 /mnt
$ cd <your_yocto_build_directory>
$ tar xfj  build/tmp/deploy/images/salvator-x/core-image-weston-salvator-x-20160927181256.rootfs.tar.bz2  -C /mnt

NOTE: probably you need to be a root user, hence use "sudo"

Configure U-Boot to boot from SD card

Proper U-Boot command to boot from SD:

# setenv bootargs 'rw root=/dev/mmcblk1p1 rootfstype=ext3 rootwait'
# ext2load mmc 0:1 0x48080000 /boot/Image
# ext2load mmc 0:1 0x48000000 /boot/Image-r8a7795-salvator-x.dtb
# booti 0x48080000 - 0x48000000'

Exaple of a proper hardware log:

baudrate=115200

bootargs_nfs=rw root=/dev/nfs rootwait ip=dhcp
