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:

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". Serial settings are 115200 8N1.

Booting Linux
* Kernel config: defconfig * Kernel image: arch/arm64/boot/Image * DTB: arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dtb (for R-Car H3) * DTB: arch/arm64/boot/dts/renesas/r8a7796-salvator-x.dtb (for R-Car M3-W)

Test procedures

 * Tests:eMMC-8bit-width: Test the on-board eMMC with an 8 bit bus width
 * Tests:SCIF-FIFO: Test SCIF FIFO behavior, using SCIF3 and HSCIF3 on expansion I/O connectors
 * Tests:SDIO-KS7010: Test SDIO with a Spectec SDW823 microSD card (using an SD size adapter) on connectors CN13 or CN14
 * Tests:SDIO-H3-Voltage-Switching: Test if voltages change properly when inserting UHS capable SD cards into connectors CN13 or CN14
 * Tests:Watchdog-Pretimeout: Test watchdog pretimeouts. Because the hardware watchdog (RWDT) doesn't support this feature, a software watchdog must be used in addition
