Quick Start How To
This sections describes steps that are necessary to run a "Hello, World!" application using Yocto build. Wayland are supported.
Build Yocto image
Refer to Yocto for steps necessary for making a Yocto image.
Connect to serial console
Use a miniUSB cable to connect the PC to R-Car V2H Wheat Debug board. CN4 must be used on Wheat side. 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 port is : /dev/ttyUSB0 flowcontrol : none baudrate is : 38400 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 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 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
Use 12 V power supply with a 5.5 mm barrel plug.
Configure U-Boot to boot over TFTP + NFS or from a micro SD card
Refer to R-Car/Boards/Yocto-Wheat for steps necessary for running Yocto.
