Kingfisher(R-Car Starter kit extension board)
Instruction of using M3SK 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. Only Wayland is 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.
- 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 Pro (M3ULCB) board. CN12 ("CPLD/DEBUG") must be used on Starter Kit side. It is routed to SCIF2 in the R-Car M3 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.
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:
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,
Use Ctrl+A, Ctrl+Q to exit picocom.
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.
If you encounter problems, make sure that minicom is configured with hardware flow control off. To check this, start minicom with 'minicom -s' then select "Serial port setup" and set 'F - Hardware Flow Control' to 'No'.
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. Port /dev/ttyUSB0, 18:31:48

Enabling Automatic POWER ON
By default, the board needs to be powered by pressing the POWER button.
It might be useful for some usage (e.g. automated testing or demo purposes...) to have the board automatic power on when the power is applied.
Hardware modification is necessary to enable such behavior.
According to the page 18 of the board schematic, the PMIC chip has a pin called RSTBMODE which switches between level and edge triggered behavior of the RSTB pin.
By default, the RSTBMODE pin is pulled up by R413, which results in edge-triggered behavior. The PWRON switch is connected to the RSTB pin, and the switch pulls the pin low when pressed.
One way to configure the switch behavior would be driving the RSTBMODE pin low trough another board attached to the ComExpress connector.
However, the schematic also shows that there's an unpopulated footprint for R424, which is a zero ohm resistor for pulling the RSTBMODE low.
A small piece of wire was soldered to the unpopulated footprint of R424 to configure level-triggered mode. Alternatively, simply putting some solder in the unpopulated footprint of R424 is enough.
When power is applied, the RSTB pin is pulled up by the internal pull-up resistor of the PMIC. This results in the PMIC powering up the rest of the board when RSTB has been configured to the level-triggered mode.
USB3.0 host can be used via COM Ex connector(CN1). But, when connecting USB2.0 High Speed device to USB3.0 host, USB2.0 connection does not work properly for any of the following problems may occur.
- The USB device isn't normally recognized.
- An error occurs during communication, and USB3.0 host freezes.
- Kernel hang up.
If you access SD or eMMC in the following environment there is a possibility of hanging up.
Please apply the following workaround patch to the kernel.
